About This Class

Let's edit your watercolours! Have you always wondered how to get your watercolours from paper to a digital motif with no white background? Let me show you how in this beginner friendly photoshop class.

Together we will scan in your watercolour painting, fix dust and blemishes and learn two different ways that we can remove the paper background leaving us with digital watercolour motifs ready to use.

We will cover 

  • Scanning our artwork
  • Opening our scan in photoshop
  • Setting up a file ready for editing
  • Removing the white background
  • Different ways to select our motif with the wand tools
  • Cleaning up edges
  • Fixing blemishes
  • Comparison of the two methods
  • Saving transparent files

Once you have digitised your motifs we will save them as a transparent PNG so they can be used for clipart, art prints, invitations, repeating patterns, POD sites, stickers and more!

You will need adobe photoshop for this class.

Transcripts

1. Intro: Hi, I'm Ashley Fish, a watercolor artist and surface pattern designer in this class. Today I'm going to show you my two favorite ways to edit watercolor, spoiler alert. Neither of them require using the eraser tool. Once you learn how to digitize your watercolors, the possibilities are endless. From transparent PNGs, clip art, invitations, art prints, and repeating patterns. You can even use them to upload onto print on demand sites. By the end of this class, you'll have learned two different ways to digitize your watercolor. We'll take them from a scan to a digital motif with a transparent background. We're going to do all of this in Photoshop. Let's get started. 2. Scanning and Resources: Before we scan in our artwork, I want to let you know that I have some resources available for you. I have the scan available for you to use for editing practice, but feel free to use your own artwork too. I also have a document with the keyboard shortcuts that we'll be using in this class. Scanning is different. For every scanner, I have an Epson V 39, and what I do is I put my artwork face down on the scanner, close the lid, and then head over to my computer. This is the window that shows up when I am scanning my artwork. I like to press the preview button here just to make sure that the colors are looking nice. And that thing, I also like to scan in at 600 DPI. This is an important thing to take note of because the DPI is your dots per inch. If you scan in at 300 DPI, your motifs will be exactly the same size as you painted them, which is great. But I would like to scan in a little bit bigger. That means that later on I can make my motifs a little bit bigger or a little bit smaller than the size that I painted them. You can choose any of these different sizes, but I think 600 is good. If you do less than 300, your motifs will scan in smaller than you painted them. It is unlikely you'll want that option. I would say stick to 300 as a minimum. I am going to go with 600 DPI today. And then I will press scan. Once it's scanned in, it automatically shows up in the folder that I have saved it in. Yours may not do this, so you might need to go to the folder that you've saved it in to find it. But once I've got it, I highlight it and then I will right click and go open with Photoshop. There we go. 3. Workspace setup in Photoshop: We have our scan open in Photoshop, and the first thing I'm going to do is show you how I like to set everything up ready for editing. We're going to need to make sure that we are all using the same layout. So we're going to go to Windows Workspace Essentials. And this will just make sure that your screen should be looking the same or very similar to my screen. This has scanned in portrait, but I would like it landscape. I'm going to come up to image image rotation and click 90 degrees clockwise to turn this around the way that I painted it. I'm also going to grab this background copy here and make another copy of it and then turn this bottom background layer off. I'm going to click this plus button here to add a new layer. Then I'm going to press the G on my keyboard for the paint bucket. You can also find it over here if I press and hold brings up these options and it is the paint bucket tool that we want and we would like it to be black. In this color panel here. There's these different options that you want to select. Color, you want to drag it down in this box here. You can see it changing, drag it down to black. And then bring your mouse back over and on top of the artwork, click and it's going to turn it black. The want to press V to go back to your normal mouse, or you can press up here. And then we're going to drag it underneath so we won't be able to see it. We're then going to come and lock this layer so that we don't select it by mistake. And then select this layer here. This is the layer we want to work on. And we need to have the layer that we are working on selected to do what we're wanting to do. That is how I always set up my workspace ready to go for editing my watercolor. 4. Method One : Now that we have our file set up, we are ready to start editing. The first thing we're going to do is remove this white background. We will make sure that we have the right layer selected here. And then I'm going to press, which will bring up the magic wand tool. You can see here, this one is the magic wand, but if you have pressed it and it has come up with a different symbol, come over to the left here and press and hold. And you'll see that when you press W, it brings up the object selection tool. Quick selection tool, or magic wand tool? The magic wand tool, the one that we want. I'm going to draw your attention up the top here, and there's a couple of settings that we want to have a look at. The first one is contiguous. Now, we would like to make sure that this here is ticked, because it means that when we select this white background, it will select all of the white pieces that are touching each other. The white that is in the middle of this flower, for example, won't be selected. I'll show you how that works with contiguous selected. If I click the background, we can see the dancing ants around here, but they haven't selected these white spots within the flower. Now I'm going to press command D to D select and I'm going to untick contiguous. And this will select anything that is a similar lightness to the background. You can see that now that I've selected that, there are pieces of this missing here, these inside white bits won't show up. Hit delete, so that makes a little bit clearer to see. You can see that all of the white pieces have been taken out. I'm going to command Z to undo that. Command D to deselect if contiguous is pressed, is ticked or checked. I select the background and then hit delete. You'll see all of the white spaces in here and in these flowers will stay there in the leaves and things like that. Again, command Z to undo, command D to deselect. The next thing we need to look at is the tolerance. I like to have my tolerance 20-40 I think that normally select all of the background without selecting too much of the artwork. This can depend a lot on how light your watercolors are. But I will show you what happens if the tolerance is too high. Say if we put it up to 90 and then select the background and delete. You can see that it has taken all of the light patches away. Even though we have contiguous selected, it has taken quite a lot. And to undo command D to deselect, now going to bring it down to 10% and we will click the background and delete. And you can see that it hasn't selected enough of the background command Z to undo command D to deselect, I'm going to go with 40% here. You can have a play around and see where the tolerance works for you and for the water colors that you are using. But just put a tolerance in, you can delete the background. And then you can always command Z to undo, command D to deselect. And you'll be back to the start, ready to try it at a different tolerance. You can also see what is going to be deleted. I have put this back to 40 and I'm going to click here. You can see where the ants are dancing around. All of the white has been selected and the bits inside these dancing ants haven't been selected. The bits that haven't been selected are going to stay there. You can see what's there. I'm happy with it at 40% I'm going to press Delete. And then we'll be on to the next step, Delete command D to D select. And there we have it. The next thing is we're going to choose a one of the flowers or leaves to bring out onto its own layer. If I come in here, I am going to choose this one. I'm going to zoom so that we can have it nice and big on the screen there. Now the magic wand isn't going to work on this, so well, I'm going to go over here and click and hold, and bring up my object selection tool and draw a marquee. Square around it and let go. And it should bring these dancing ants all around the edge. I'm then going to zoom in and make sure that it isn't in any of these white patches because I want these white highlights in there. We can see here has these dancing ants. I'm going to select it again and that gets rid of them. I think that, that is looking pretty good. All the dancing ants are around the edge, which is what we are after. Now, if you come in here, you can see that some of the white is still there. I'm going to go and click on this and press this quick selection tool. I'm going to use my left hand bracker, just next to the, on your keyboard. And I'm going to press that to make it smaller. If I press the right hand bracker, it would make it bigger. I'm then going to click on Option to Museum. So you can see it has a plus on it at the moment. But if I press option, it will turn to a minus. Can you see that? Plus, minus. I'm going to use this minus and go around and select some of the white in here. Okay, that's looking pretty good. I'm then going to go up to select, I'm going to go modify contract. This is going to bring the ants that are in here in a little bit. I would normally do one pixel, but I'm going to do two just so that it is a little bit easier for you to see. I've popped it on two pixels and I'm going to click okay. If you looked really carefully, you'd be able to see them jump in, Let me zoom so you can see. Can you see here? They're not on the edge anymore. They've moved a couple of pixels in. I'm then going to right click and layer via cut. You can see over here that it's popped it onto its own layer. You can double click here and name it if you like. What we can see is if we turn off this background layer, we can see that all of those white edges have disappeared. You have a flower here that is pressed V, which is this move tool here that we can now move around. It's ready to be used in whatever project you want to use it for. Here you have your perfectly edited flower. It is now on its own layer and has a transparent background ready for using however you want to use it. Right here you can see all of those white edges that we took off. If you did one pixel, it wouldn't take off quite as much as two. That is an option to play around with to get the look that you like. That is the first way that you can edit your watercolors. 5. Method Two: I have my file set up the same way with the background layer that we can't see, the black layer that is on and also locked. And we have this layer here selected. What we are going to do is we will now do this flower here without removing the background layer. You press the W for wand. I like to use the quick selection tool for this. I'll just use the right hand bracket to make it a little bit bigger so we can see it. I'm going to click and drag where this motif is. Then I'm going to zoom in and have a look And make sure that it has selected around the edges, it hasn't missed any bit. Sometimes these lighter patches that will miss. To get this one. I'm going to use the left hand bracket, the bracket next to the P on the keyboard and select that. I'm going to come all the way around the edge and just make sure that it has selected everything you can set cut off along here. Make sure that it's all selected. I want this white patch in here to be selected. I don't want this white patch here. I'm going to press option to turn it into a minus and then click on that bit. It's taking it away. Then sometimes you just need to go and give it a little click to add some of these bits back in. Again, we'll keep moving around. It's got this light patch which is good. Don't want this patch here. I'll make it smaller by using the left hand bracket Option for the minus. Carefully get rid of that selection there. It's done the same here. Again, option for minus. And it accidentally, you can see the ants here. Accidentally taken away all of this. I'll just re select it again. There we go. Looking pretty good so far. Take that out there. Now the line cuts off here, which is fine. I quite like having these white patches been to show the highlights this bit. Selected. Perfect. Now we can do the same as last time where we went up to select modify contract, but I'm actually going to show you a different way to do it which gives you a smoother edge. And I'm going to come up here and click Select and Mask. Now this has grade out the background that's not selected. The area that is selected is showing in this normal brighter color. If we zoom in here, you'll be able to see where it's darker here, it's not selected on these bits are. You can go around and re, select in some of these bits here if you want to, just by clicking gently to make sure that it selects those bits that you want. But one thing I like about this tool is it gives you a really nice, smooth edge. I'm happy with that. If we have a look over here, I don't really play around with the settings too much, I just use the same ones every time the opacity, which is how dark this background is. Then I have got the radius set to zero, smooth set to 74, feather is on none because you don't want blurry edges contrast at 42, shift edge at negative 73. Feel free to copy those settings and I'm going to click okay. Then I'm going to come back over with my mouse on the flower and again, right click layer via cut. If I come into my layers panel and press this eye for visibility on the background copy, it would take the background copy away. We had just left with this flower here. You can see that this method has much smoother edges in the other one, which I quite like, but sometimes you do end up with these little white patches here. You might like them, you might not. What I like to do with these little patches is I'll make sure that this flower is selected. And you can come in with the magic wand tool. You can click if you've got contiguous, selected it, just select the bits that are touching it. Just select that and you can delete it. You can go and do that with the bits that there are white patches that you don't want to be there. I didn't like how it selected that. I will just control Z and get rid of it. Go around and delete these little corner patches. Well one more there then command D to make sure nothing's selected. There we have it. I'm going to name this one the F, Can't spell pink flower. That is it edited for you. The background has been removed. 6. Method Comparison and Fixing Blemishes: I would quite like to show you these two motifs side by side. So you can see the difference with the editing. The main difference here is whether we went to modify contract or whether we went to select and mask. I'm going to press command to open a new window. I just got 12. 12 inch one here. And I'm going to call it flower comparison. I'll create it. I can drag and drop this one in, and you can see it here. And I'm going to go to my first one that I showed you and I will drag and drop this one in. Let's sum. It is a little bit harder to see with the white background, but this one here has more wobbly edges on it. And this one here has smooth edges. I'm going to give these a black background so that you can see more clearly. I'm going to click this background layer here. Then click Plus to bring in a new layer. And then we're going to go and press D again for the paint bucket tool, but you can also find over here. And click that's a layer here. And I'm going to lock it so that we don't select it by mistake. Now I think you can see more clearly the difference. This here is more jagged. This one here has a smoother finish on it. It is really up to you with how you prefer to edit your water colors, what workflow you find best, and what kind of look you're after at the end, whether you prefer to remove the background first or not. This orange flower here, we used the select and modify method for that. This one here, we used the select and mask for the smooth edges. I am going to show you one more thing so that if you have any little mistakes on your water color or things like a little piece of hair like this one for example, that has scanned in how we can get rid of that, I'm going to press J on my keyboard that brings up this picture of a sticking plaster which is the spot healing brush. And make sure that I have the correct flower, the orange one selected. Then J for this spot healing tool. I'm just going to go over all of these little bits of here. There's a bit there, here and there. These might have been on my scanner, scanner or my paper when I scan this in. But sometimes you just get little areas of pigment that you might want to be fixed up. There we go, That's fix them all. To do the pink one, we need this flower selected. So you can select it by clicking here or you can press V, which gives you this move tool. To select it, we'll go back to this one here or press J to get there. We'll zoom in and just go and have a look and see if there are any imperfections in this one that we have a piece of hair that we want to tidy up. There we have it. Two watercolor motifs that have been beautifully edited ready for your next project. 7. Saving and Exporting : I bet you are wondering how to save these beautiful water colors so that you don't have to go and do this all over again. The first thing that I like to do is want to have all of my watercolors edited. I will pop them on a page like this, and I will call it my working file that has all of the edits. And I will save that as a Photoshop file. I might go file save. I would call this flower comparison working file. If you are wanting to save these as an image with a transparent background, what you need to do is save them as a PNG. If you save them as a Jpeg, they won't have a transparent background. And what we need to also do is get rid of this black layer. I'm going to unlock it and click and drag it to that little rubbish bin there, and it's gone. We also need to get rid of this white background layer. I'm going to unlock it again. Click and drag. Now you can see this gray and white checkerboard. That means that it is a transparent background. So if we have a whole board full of different motifs, or even just these two, the quickest way to save it, so that it saves exactly the right size, is to go file export layers. To file, each layer will save as its own file. That's why we have an orange flower and a pink flower on different layers. To click that, we make sure we are saving it where we want it to go. It is called the same name that your file is called. Flower comparison Working file is what? Minus I'm going to select a PNG, I just use a PNG eight. Make sure that transparency is selected so that we have a transparent background. And you also want trim layers that is going to get all of this extra space around here away. And make sure that it is just the size of your flower going to click Run. Then it will tell you that it's successful and you can press okay. And I will show you what they look like now that they're saved. Here we go. The flowers have saved here. You can see that it is just the size of the flower. It is a PNG, and if we double click to open it up, you can see that it has a transparent background. Open this one as well. There we go. They have all saved nicely. You are ready to use them however you want. 8. Final Words: That's it for me for this class. I hope you are feeling much more confident when it comes to editing your watercolors. I would love to see how you got on. Please post your class project in the Project and Resources section below this video.
