About This Class


One problem all book makers encounter is a warning that the files they are using are too small - printing requires a lot more pixels than a simple display on the web. Help is at hand - by resampling or interpolating the file you can add or subtract pixels to make the image larger, or smaller.

In this lesson I show you how it's done, then show you how to Batch the resizing process in Elements - using its Process Multiple Files feature - and how to achieve a similar results using Adobe Lightroom.

The Photo Book Wizard


Hello, My name is Robin.

I have been shooting photos for 40 years, commercially, for stock, for weddings, for audio visual designers and for editorial. I have also been a magazine editor and publisher for 15 years. During that time I authored several books on imaging technology and post production, so I think I'm in a good position to teach others how to get great looking images - and put them to good use, either by printing, or through the production of fabulously-designed photo books.

Like many photography teachers, I'm in the enviable position of being able to combine one of my life's passions, photography, with my job. And, even though I tend to spend way too much time in front of a computer, it remains one of the best jobs in the world...

1. An Introduction to Resampling: Hello, My name is Robin Nichols. And welcome to this episode off the photo book Wizard in this lesson will be looking at what to do if the image files that you're using are not the right size on what typically happens in most bookmaking software. If they detect that there's a resolution problem, you'll get a warning symbol saying we want to resize this to the size that is safe to a size that will reproduce the picture. Reasonably clear. This may not be big enough for you, so you may be working on a book project that involves importing photos from old smartphone shots, maybe old scans that somebody in the family has given you. And they may present this problem so we'll show you how to re sample the files so that they not only become bigger, but you get rid of that warning sign in your book making software. I'll also show you how to crop pictures to specific dimensions. That's a very useful tip, not only if you're making a digital photo book, but, for example, if you're taking pictures down to the local High Street photo lab and you want to print everything to a certain size, for example, six by four inches, or five by seven inches. The photo book wizard is a serious of lessons on how to improve the look, design, visual impact and professionalism off your picture book projects. Using a range of easy to follow photo shop and photo shop elements, techniques, bookmaking, software and layout creativity, the Siri's is designed to give you total creative control over both the content and the design of your book project. Each lesson comprises several videos running through the particular effect that we're trying to achieve. Some involved just the bookmaking software itself. While most include a bit of photo shop and furnish of elements with tips and tricks for using these effects in the book design, almost everything you'll learn here can be achieved using photo shop elements or photo shop itself. But on the rare occasions where a tool is not shared by both programs, I'll let you know and provide a suitable work around simply because there's nothing worse than following a how to video for a few minutes, only to find it won't work in the software version that you use and there's plenty of time for you to put these techniques into practice with the associated lesson projects. Don't be shy. The best way to learn anything technical is actually to try doing it a few times yourself on. The most important feature of these lessons is that I provide feedback, which is a great learning tool in itself. And if you'd like to leave me a comment about the work that you're doing or the results you're getting, don't hesitate because I love to see what my students are up to. 2. Enlarging pictures - Resampling: have again, folks. Robin Nichols back with a little bit of trouble shooting advice. Now, sooner or later, in your book making process, you may run into trouble because the images you're trying to use don't have enough pixels in them. So these might be in this case, I downloaded a picture Fidel Castro, because I'm taking a photo tour to Cuba and I need Teoh give a little background information about the fella. But you may have, for example, low resolution scans you've got of your great grand parents from their photo album, that kind of thing. Or they may be from a low resolution digital mobile phone or even a low resolution digital camera. And I can old camera that only has goodness may only has five megapixels in it or something of that nature. So when you get to a stage like that, you may think I gotta get back down, bring it down in size. What are we gonna do here? In fact, I can click on the fixed button. So what it does is it warned? You and I think most software that I've used does have this warning and the reason it has this warning is they don't want you. For example, if you think I'm just gonna have this full page, it's gonna be 13 inches across. So, you know, even though on a screen it looks pretty good when it prints, it's gonna run out of pixels. And that's the problem. Gonna run out of pixels. But essentially in print. Unlike the Internet, you need every pixel you can get your hands on. And if you don't what it does, I think the printing process is amazing. What it does is use a process called dithering. So instead of actually seeing pixels because they've spread out so far apart to get to make a big picture because they spread out so far apart, it actually did ism. So it actually puts fuzziness around the edges. And so dithering is amazing for smoothing out faults and problems in a digital imaging. But at the end of the day, the picture just goes out of focus and you're gonna look again. Yeah, that's not very good at all. So, of course, blood and a number of other companies that apply this little fella here. If you click fix, that's the appropriate size. No bigger in order to print this. So you might think Well, you know, that hasn't really fix the problem because I still want Fidel to look nice and big. So let me show you how you do this using a photo editing program. Here he is in Photoshopped Elements. This is an awesome little program. Cost you 100 30 bucks and will allow you to do almost anything to your digital pictures, including big them up. Let me show you how you do that image from the image menu at the top of the screen. Here is just a fancy word for photos or pictures, and we want to resize the image. And we actually want to resize the image size so the images like the photo size, you know, it's it's all very sort of strange language linguistics they use now the process is called re sampling, and I could see it. It actually it's resembling or interpellation. And so what it does is read the pixels in the image and goes, OK, well, we've got six million. This guys were any two point it. So maybe you've got 1.5 1,000,000 blue pixels, half a 1,000,000 sort of pinky pixels and then half a 1,000,000 green pixels, and it just adds extras. So what we do is generally when you open this little utility image size, it's the re sample images not checked. So I'm thinking for blurred book smart and in fact, any other bookmaking we want have 300 pixels per inch. So I've just typed in 300 pixels per inch with this re sample image unchecked. No problem. But also the number the pixel dimensions remains 2.88 million. But now I'm gonna think I'm gonna re sample them now elements and fed a shop and other programs offer you a thing called by cubic interpolation. Boy, that's a bit of a mouthful, Isn't it? On? What that does is, as I said, it just assesses the image. And somehow some clever guy or woman has sorted out this this algorithm. So it just works out. How many extra pictures the red. It's amazing. This program now has a best for enlargement and a best for reduction setting. So I'm gonna choose best for enlargement, and I'm thinking the width actually needs to bay instead off. I can only do percent. Let's go document size inches. It's only four inches wide. Well, I'm going to try and make it. We're gonna make it. I think the pages about 13 inches. I'm gonna make it a little bit conservative, Let's say eight inches wide by 5.5 inches high, so you can see the proportions are locked off there. So you really don't want to unlock it or unconstrained proportions Because then poor Fidel were turned a little bit weird and be stretched on the screen. So that's converting. Are adding an awful lot more. So it waas nearly three million pixels and then it's going to be 11.5 million. So we're adding a heck of a lot of extra pixels. Click on. OK, watch what happens power. So now you see at the bottom it says Doc, 11.5 million. He's looking even more confident, and we'll save that as a J pic, of course, and imported back into blurbs book smart and see what happens. So here we are, back in book smart, and we have this one here. This is called Fidel bigger. I'm gonna drag him in there and bang world that looks pretty good. So that's coming at 13 by living. So there rules about having 300 DP I 13 inch wide pictures can be stretched as well cause, Remember, I didn't actually set this to 13 inches. Let's say a line center don't crop. So even then I've actually gone and enlarged it even more, up to 100% so that it fits the page beautifully. Where is the warning sign? We don't have the warning sign anymore. He still looks. He looks a bit rough around the edges. This is downloaded off the Internet. It's been a J pickets bean over compressed, so it's gonna look a little bit rough. But we've just added about nine million pixels to this, and it's looking pretty good. So that's a process called re sampling or interpellation. Very, very useful. If you have small files that you want to a large now, before I go a word of warning. If you've downloaded an image and it's only half a megabyte 500,000 kilobytes or 450,000 kilobytes, you may think that's a big number, but you're starting off with very, very little. So if you suddenly decide that that needs to go on your front cover. You think I've got a big it up to about as I did hear eight or nine inches wide because you're adding a massive amount of increase to very little information. The picture really will look soft. Here. I was starting with three million, so it was kind of okay to actually go up to about nine or 10 or 11 million. That was acceptable. So there is a limit to what re something could do. It's not a magic bullet doesn't fix all your problems, but it's pretty darn good. 3. Cropping to a Specific Size: one tool that I think you'll find pretty useful when it comes to sizing pictures to go into a photo book, for example, or even just sizing pictures to get into the photo lab to be printed is the crop tool. The crop tool in fellowship and fellowship element is pretty close to identical. It's kind of similar in light room, but not quite the same. If you just press the letter C on your keyboard, let's just try that. There we go. Let it let us seal the Cuban or trying again. There we go. It automatically selects the crop tool. It looks like that these are actually cropping tools. And back from the days when we had film graphic designers, etcetera used to run these two movable right angle, 90 degree bits of cardboard over a print or large format. Negative just to see what it would look like if you shot it. For example, Ah, horizontal, vertical, that kind of thing. So this is why we use the crop tool. We can just move the Marquis in and out to chop off bits of the picture. We don't we don't need. I think most people use the crop tool is a kind of supplementary compositional tool. You know, scything argue. We should kind of being a bit over here on the water for another shot, sort of been over there and maybe push it up a little bit. And that makes a better picture. So going from a 60 megabyte file, if I say yes, that's OK to croak, it's suddenly gone down, too. Well, look, 2.9 megabytes has gone down to a tiny little picture, so I need to undo that Control commands it and investigate when we use the crop tool. What happens is this weaken sit in a particular parameter. So if I click and drag okay, you can see I can actually drag it all the way down. That seems to be a bit at the bottom orbit at the top. What that means is it's set to a pre determined space, and you can see it's 12 80 by 800. So if I say to it, look, just do width and height resolution. Okay, I can then put in a certain pixel amount or inch or centimetre amount up here. Let's say we want Tokyo seven inches wide, so seven i n for inch is very important to put the i n. But otherwise Photoshopped doesn't know what it's doing. Seven inches by five i n inches high resolution. Let's go 300 because it's going to be printed. So now you saw the crop Marquis changing a little bit, and it means any time I press the crop button on the OK button, whether it's a tiny little crop like this just on the rocks in the foreground, or a much bigger crop like this and you see it snaps between horizontal and vertical. If I really push the cursor up, if I go like that, these two sizes I've just chosen will come out at five by seven inches at 300 dots print. If you don't believe me, let's check it out now, so I compress Enter. It's gone down to a nine megabyte file. If I choose image image size, it's going to tell me it's five by seven inches at 300 pixels bridge, so it kind of crops it to the size that you've chosen and sets the resolution you chosen. So it's very, very handy, as I say again for re sizing pictures. So, for example, if you've got a very big size picture, this is a 60 million pixel. A pixel image is a very big size. Let's say I've got a 10 inch by eight inch landscape book and I'm thinking, OK, maybe I want to have a portrait here, so I'm going to choose five by seven. Let's choose. I got to say 10 inches by eight inches. I want them, let's say six inches by eight inches, so I'm gonna go six inches, six inches across. I think we'll go eight inches across and we'll go five inches high. There we go. So now I can crop this very simply. Just click the commit button on top right on. There's not gonna be six by eight or eight by six. Whichever way you around, you wanna go and describe it? Let's check it out in the image size box eight inches by six at 300 dots. Pinch. Just tip number one. Don't forget to put the I N. C M P X for pixels into the fields marked because otherwise it may not work. You can choose from some of the automatic already set parameters that Photoshopped gives you that adobe gives you, or you can create your own by saving it as you can with most of the functions within this program. If you want to start again, you just click on clear and then types and Maurin. The nice thing about this is again I put in eight inches by, let's say, eight inches by five inches. You can then click the button in the middle just to go vertical or horizontal, so the cropping tool is an excellent little functionality. One other thing about the cropping to which I think is pretty neat, that most people probably don't know but may have experienced is this. If I click and I dragged away across the crop tool, I've already got him a preset think so What I'll do is I'll turn that often saying, No, I don't want to. Something to say nothing. Original ratio. Let's go like that case that's full frame, right? And then, instead of just cropping, I'm gonna pull it out a little bit Who? Look at this. So what I'm gonna do here? If I could get that more or less even I can just drag this down a little bit more or less even know quite even there. But we'll have to. We'll have to do with it. There we go, and then I click. OK, because I've dragged it outside of the cropping area. It's actually added pixels. So it's made the image got to 94 is at 94 84 million pixels. Let's just undo that. And I'm just gonna press d on the keyboard and X because I want to actually add some pixels . Let's have a look here. All right. Need Teoh. Just swap that round goes on to add white. So you have to stop because it won't allow you. And then the second pull pulls it out either side like that. We're now we got a white background. That's just see if we can at that up and get it nice and think. Now, why would you want to do this? Well, sometimes it again for printing. It means that you've got a nice of border it very good. You can slide them into plastic pockets, so you get an instant sort of presentation happening. Instant portfolio or indeed, you can just add white border like this if you're floating him on two pages that you've chosen in a photo book, for example, with patterns, textures or a different color to white so that they sit rather like a traditional stickum in a photo album sort of feel. 4. Resizing using Lightroom: now, although I think the process multiple files feature that you're finding finish up element is excellent. It's it's very, very good. And considering this is a mom and dad sort of entry level consumer product, what it can do is just awesome. It is very, very good, I think, actually, the out putting capabilities of Adobe Light Room having having said that a somewhat better because A. I think it's a little bit faster and be it has some other features, such as adding a really good copyright symbol to every image. Should you wish to do that, which is way better than elements? What elements will allow you to put a little water mark in there? But it's not very creditable where it's pretty much everything in light room can be edited to your own personal taste. So let's go ahead and have a look at how we can help put pictures. Now, I have start a whole bunch of awesome pictures here, as you can see here some of vertical summer horizontal, so these just really exercise. I've selected them all, and we're going to hit the export button so it immediately comes up with the export dialog box and he says You want to export 141 files? I think, Well, why no. So the key thing here, obviously is. Have a folder somewhere on your desktop, normally or somewhere else tucked away on your computer so that you can actually put them into. So I've chosen here specific folder and I've gone and books I've gone and clicked on Choose and I've chosen. When it's called resize a cunningly named resize, you can put them into a sub folder. You can reintroduce them to the catalogue. Should you wish to do that. That kind of thing. Now one little work around thing you need to know about light room is I see my students do this all the time, that kind of massing up in the gut to the error and they click on that and then they flick on the next era. Andi just gonna die waiting because you know it is fiddly to do. The cool thing is here you can click anywhere on these light grey bars and it just opens or closes said, You know, maybe the arrow there is a little bit misleading, so just click anywhere on the bar to make your life a little bit quicker. So hey, just like process, multiple thoughts. I can, of course, add a custom name or a farm name or whatever to it if I want to. I don't think I'm gonna bother today. Today, but as you can see, it is example Iceland 678671 or whatever. And you can say lower case throughout the case. Okay. Found naming video. Well, that's not pertinent to reducing image size. The file settings are very important. If it's going into a photo book, of course, you want to add either J pegs or PNG files here. We've only got the original only the original DMG tiff, Pierce City or J Peg to choose from. So of course I'm gonna go J pic and I want maximum quality. Maxim acquitted. I don't really want to see any compression artifacts in my out put pictures. So the color space well again, it's a mute point, really, isn't it? You know you'd normally go for something like adobe 90 rgb 1990. It simply because that technically gives you a wider range of colors. Most monitors don't display those colors on a standard monitor. So a lot of people say, Well, why not just choose s RGB? And then you won't have too many horrible surprises anyway. So that's again something that's worth testing, but J. Peg best quality. The next setting, of course, is the image sizing, and I want to resize them now. They're really neat about this neat thing about this program. Is you'll always run into this problem when you're always run into this problem by having vertical and horizontal in the same box. And you saw in my Icelandic pictures there I had some verticals had some landscape format one. So that's a real problem with programs like further Shop Elements because you then have to calculate the percentage reduction. You know, that's okay, but it's not terribly precise. What this program has, of course, is the ability to say, Look for the longest edge and I wanted to be, let's say, the longer stage 2000 pixels with a resolution off 72 DPR. Let's say this is going on to a block, So 1000 pictures, 72 dp I very, very good on that's That's excellent, or you could say, look, if it's going to be in a 13 by 11 inch digital photo book, you could say, Well, let's just make everything 12 inch along the longest edges. If you want to do that, I'm gonna go back to pixels and just choose 1000 A ziff. We whips as it will. We're going to add them to a blogger auto website so resized to fit its collapse that do you want to add some output sharpening? Well, I'm kind of thinking it depends if these are just raw files or if their files that you really haven't edited. Yes, maybe you do, and you got options for screen, obviously Web or met paper or glossy paper. And then, if it's screened, you can crank it, crank it up to, you know, high low or medium sharpening. I'm going to say, Let's not bother with that For the time being, I don't need to think about the metadata unless there's some copyright information in there that depends exactly on who you're uploading them to, or we can add a watermark, okay? Or I can add a custom walker watermark so I could just say, Look, here's robbing one, which is one that I've made up or I can edit the watermark. And for example, let's put my name in there. You can, of course, put a registration number in their copyright symbol. There anything you like and this is amazingly complicated account. Good. This is. And it allows me, for example, to choose the front I wanted in. I can choose a PNG or J pig image if I've got a company logo. I can do that. You know, if you're making a book on company products, you could have your logo inserted pretty much everywhere. Anyway, You want bottom left? Bottom right, Center. What have you on? You can have a line. A line that text in the center. What's covers the text gonna be? It's just so we're gonna make it white. That's fine. Do we want to have a bit of a drop shadow? Yep. Do we want to offset that drop shadow, etcetera, etcetera. You can just about see it just appearing in the window. That's very faint. Let's say Okay, so you put a drop shadow in, we can have a watermark effect. Let's say brighten it up a little bit and in fact, I think I want to make no offset. Make shadow a little bit A little bit slow. Isn't radius change the angle? Offset. There we go. Let's just make the angle just underneath a little bit. Maybe capacity. You know, we can have a subtle or as blatant as you like. That's just a little bit of an extra thing for you. And then do we want to make it proportional, or do we want to fit the window? OK, fill the window groups? No. Or do you want to get proportional Some to say proportional according to the size. Oh, right. And then the anchor is exactly you know where exactly in the picture is gonna be in. Let's just you safe. So I'm just gonna call it Robin Robin to. And that's the wonderful thing about light room. Of course, unlike fellowship elements is if you customize something, you just save it and use it again. And I'm gonna get so they've got a watermark and post processing do nothing. So let's just export them. So we get the usual thing. We get a little bit of sort of tedious waiting on. I've said I'm just joking. It's not really tedious because it's incredibly fast. And here in my image is being processed in just cranking through. How good is that? That is amazingly fast. And if I choose the properties you can see these are just websites. So there are 1000 pixels along the longest edge, and they come up to about 500 kilobytes, so I can send 10 of those in an email. No problem at all. And that, very simply is how you met. You manage the export in this case of 141 fast to resize them for your Web, for your blawg, for printing or for putting into a digital photo book. 5. Process Multiple Files: Hello again. Robin Nichols, the photo book wizard back with You Today with a really good feature in fellowship elements . And you think, Well, I'm making a book. Why DOn't need Financial Element? Well, this is called Process Multiple Far's. I think it's a very under played features, like a little utility that works inside fellowship element, and it allows me to take a you know, 10 or 100 or even 1000 pictures and resize them just automatically as I go away and have a cup of tea and put your feet up for a while, read another chapter in my book and then bingo, probably before I've turned the page, it will have done it. So it's very good if you make a good book. If you want to resize a whole bunch of pictures at the same time, it's very good if you have a blogger, a website or if you just like emailing people pictures and you want to reduce them down 2000 pixels or something like that. So it's small enough to email on mass or upload to a blogger website. So it's a fantastic little feature. Let's have a look and see how it works. We go to the file menu. Of course, this is probably the generic spot You start in most applications looking for stuff that file new file open, etcetera. 2/3 of the way down it's is far process. Multiple files are So this is where you probably look at and go nap. That's not for me. It's too busy fighting complicated. I quite understand. It was the first time I looked at this. I thought, you know, that's a bit on the hard side. The key thing to remember is you need probably two folders, one with all your pictures that you a ridge. They're originals and one with pictures or this empty waiting for the resize pictures to be automatically dropped in there so I could see I made a mistake here. They're both exactly the same here. So I'm just gonna browse on this one and set it to resized. I think it is gonna choose. Okay, so now it's going into a folder. Courts group Skill share, re sizing resized versions. How easy is that? So source and target or source and destination. Very important. Look, you can also rename the files if you really want to, so I can literally click in where it says document, name and in type in African animals, for example. It could be African animals, and then I can choose from the right end drop down menu. That's a three digit serial number, and it's saying it's gonna be called African Animal 001002 and so on and so forth. So let's try doing that. But underneath that is caused the re sizing images, little checkbook that is really important. So what we've got here, if I click on this, is the ability to resize according to inches, pixel centimeters. Mel and percent percent is the important thing, because if I say let's resize them according to a measurement like inches or centimeters, it's a little bit tricky. If you've got vertical and horizontal pictures in the same folder, you can, of course, do it twice. Once on the verticals on once on the landscape, horizontal images. But to be expedient, just choose percent, and I'm going to say, just say, Make it 75%. Okay, I'm gonna make it 50%. I'm gonna reduce it. That's a 50%. Can we try that making sure that constrain proportions is entered there because otherwise the width will be 50% smaller. But the height will remain the same, and you're completely destroyed the picture. We also need to set a resolution, and I'm gonna er on the side of caution and say, Look, let's go 200 farmers going to my blogger something I'd probably choose 150 or 96 or something of the nature or even 72 on course. I want to constrain the proportions. Here's another neat little feature like this A lot it says. Convert files, too, J Peg, etcetera. Let me just push this up the window so everybody can see the drop down menu here. So tiff PNG pick sites such what is a pick side? And I don't know what a picks picks off five format is, but certainly a tip for PNG's very handy. If you're gonna import them into digital book PNG and, of course, J Pig, I'm gonna said it to J pig max quality, because that's what I want. We also have Top writes, the ability to add a quick fix function to all the pictures that your streaming through and again, as I say, this will work on 1000 pictures if you want to. Kind of think there's no point. Unless, of course, these are just raw files. These have just come straight off the camera. You want to boost the contrast, the brightness, all the color. Then by all means do it. Normally, when I do that, I will have edited the pictures anyway. So I think, you know, they look pretty good color. And so I'm gonna just run it through and leave all the sharpening and stuff to what I've said it to. I don't want to actually add extra sharpening or whatever to my images. And then finally, we got the ability to add labels. We can have a file name. If the has a phone name, we can have a caption end elements. He's even has a watermark function. I'm gonna put it in there anyway. But I'm not very hopeful. I don't like this process. I don't like this particular product simply because, and I'm gonna make the capacity 35% simply because it's not very intuitive. Adobe Light Room has a far better function for adding a watermark or copyright symbol to your images on Mess, and I'll show you that in another lecture. Let's click OK and see what happens. So you can see it's kind of doing stuff in the window there. And if I go back to my re sizing and have look at resized versions, you can see by the time I've finished talking, it's actually done it after I made a mistake up. So you know it's got African animals 003456 whenever. So it's incredibly fast. If we click on one of these pictures, this is 3.68 megabytes. Where's the original? Of course, Waas. Wait for it. Wait for it. Look here. We'll just have a look. The original was much, much bigger from memory. It is huge. It is 17. So we've done a very good job of just crunching the numbers and how fast that took a few seconds. So it's a process called process multiple files. It's for batch processing, a whole load of functions like changing the far format, changing the size and even changing the editing like the color on the contrast in the sharpness. If you want to do that as well as adding a copyright symbol. So if I go and double click on this on, you can see here it's actually missed off the copyright symbol. It should be slap bang in the middle. It's not so it's a little bit flaky on the copyright thing. I'm a little bit disappointed with that, and I'll show you how that works in light room in another lesson.
