Transcripts

1. Intro: Add/Replace Objects: Hello and welcome. In this class, we're going to learn how to use Photoshop to add or replace objects into a photograph, will take everyone's through two very different tasks. One will add this pizza to the sea, will consider its placement and appropriateness. And then we'll go ahead and mask out the occluded areas, add shadows, and make sure it fits into the overall layout. And then second, we'll add this woman's face into the places somebody else's will need to consider lighting, blend, shape, and how to make it look Valley natural overall. These two should provide you plenty of examples of tips and tricks you might want to use when performing your own Photoshop. I'm super excited. So let's get right into it. 2. Swapping Faces: Overlay: Okay, so our first task is going to be overlaying this lady's face onto this particular image here. You can see it's pretty badly taken the photo, and it's pretty overexposed. And overall not a great result. So let's go ahead and try to overlay this one onto here. So first we'll grab the image and I'm try to adjust the size so that it fits. And then we'll look at the tonal capacity down so that we can try to fit it exactly on top. So I'm holding down the Shift key and dragging this is note here, and that would maintain the aspect ratio. And I'm just going to try to get it such that the two phases are around the same the same size and shape. Okay, great. And then I'm going to add a Vector Mask here. And I'm gonna paint directly on top. So when I go ahead and paint this, I am painting a black layer, which means removing removing an area here. So if I go ahead and increase the capacity 200, you can see I'm taking away areas of the image. So size up a little bit and just tried to remove areas that are conflicting as much as possible. Okay, great. So next we want to blend the hair in to the background image. So I'm going to tone down the opacity and see if there is a natural fit. It looks like somewhat. And if I slide this slide that right up to the top, you can see will not paint a root two will add. So I'm just gonna go ahead and try to add back. Some of the elements are taken away. 3. Swapping Faces: Lighting & Tone: Okay, great, so that looks all right. Let's go ahead and add a photo filter here so that I will adjust the colors so that they didn't match. So you can see this one down here is a more yellowish color. So I'm going to go ahead and adjust this for more yellowish color. Okay. Let's go ahead and add some brightness as well. Okay. And looks like there is a hint of blue, this as faint as it might see. And I think adding it, it will look, we'll make it look a little bit more realistic. Let's go ahead and add just the smallest, smallest possible amount of the cyan or possibly deep. Okay, I think that works well. Ok. And then I think let's go ahead and add one more. Just a woman filter. That that probably does it. Okay, so that's looking, that's looking pretty good. Next, you can see that this one doesn't match the background here, so let's go ahead and make sure it does. So. So this is, this is absolutely perfect because we already have all of this setup for us. So let's just go into duplicate. Layers. Will scale up so that it fits here. And again, we'll toned down the opacity and try to fit it on as much as we can. Okay, so that looks good. But of course, if I take the opacity is not going to be blurry like that. So I'm going to do is apply a filter to a layer here. And then let's make it actually a smart layer first to Smart Object. And then now when we apply any filters, will be able to undo them, would ease or modify them with these. So I'm gonna go into blurred, into Gaussian blur. And then we're just gonna take one that looks looks like it would fit in with the background. So maybe somewhere, somewhere here as good as if I am dealer. And see. It's about the same blurriness as before, which is exactly what we want. Really. 4. Swapping Faces: Finishing Touches: Okay, and then you'll notice, if I zoom in really far enough, you'll notice that the background is actually fairly greatly. You've got this Dustin scratches thing going on, whereas the foreground is, is perfectly, perfectly clear. So let's go ahead and add some artificial noise to our foreground. So let's go with a add noise. And we wanted to, we definitely want monochromatic noise because it's the same as before. I'm going to ask just adjust this such that 2 where we think it fits well. I think around here is perfect. Within this one makes much difference. Not even sure what it does. But I think it's still a little bit too heavy near the bottom here. And that starts about, about perfect. So I'm gonna go ahead and apply that. And you can see it's beginning to blend in a lot, lot better. You can see that this one is a little bit too bright for the blurred section. So I'm gonna go into brightness here and just turn it down ever so slightly. Ok, that's great. And then finally you can see we've got a little bit here overlapping the foreground. So again, we're gonna go in and just remove that. So we're gonna go ahead and again create a Vector Mask. And we're just going to get rid of this section here. Let's assume Lynn. And sure we have the black selected. Just gonna remove this section as much as we can. Ok. I take US looking good. So let me go ahead and show you the pre the before and after photos. And I think I think you'll agree it's not too bad for tablet job. And we'll see you in the next section. 5. Moving Pizza: Object Selection: So for our first task, we're going to be incorporating this pizza right here into this section. Here, I'm replacing the plate. So you can see it's quite it's occluded by quite a number of things. And there's going to be quite a task to make it look natural. So first of all, I'm going to mask out the pizza here with the Magnetic Lasso. If at any point you feel like it selected a point that you don't want to. You can simply hit the Delete button on your keyboard and they will undo that point. And you can have another go from there. And occasionally you feel that it's selecting the same point that you don't want over and over again. In which case you can hit the ALT key and hold the Alt key on your keyboard. And it will override the magnetic elements and you'll be able to select whatever you want. Okay, so that's our first, first go. We're then gonna use these guys up here to to add to a mask provides more correct. You can see we've left out sections here. Okay? And then finally, I'm going to remove some of the extra seizing this guy here. Next, we're going to use the polygonal to fine tune our mask here. You can see it's not quite perfect. So let's, let's go in to remove mode is take out these edges here. 6. Moving Pizza: Overlay: Okay, and once you have your with your mask here, let's go ahead and copy this into offered graph. Right? So I'd like to take the capacity down to about 50% so I can see where I'm not placing it and what I overlapping it with. So we want to get rid of all of this plate. So maybe somewhere around here, maybe something like that, right? And I usually do not recommend adjusting the aspect ratio of your image. But I think in this case, a very small modification is acceptable. Okay. Let's have a look at that. Okay. Now should be. And I think dot-dot could work. And let's get rid of this piece of bread here, and let's remove the occluding objects as well. So, so first we will take out the breath. I'm going to use my patch tool here. And just try to do a blanket patch. Okay. Let's go ahead and use spots to healing tool. Just paint over as much as possible. Okay, great. Next will want to get rid off the bits of the pizza weights of hidden. So again, we're going to use the tool. Yes, it's much better. 7. Moving Pizza: Casting Shadows: Okay, great. So we've, we've removed the occluding elements. And finally, I think it's time to add some shadows. So I'm gonna go ahead and add an additional layer here. And I'm going to select the area with the pizza so that we'll use the paintbrush. Only color the areas with the pizza. So if I say D, something like this, you can see that I can't draw on any area, does not select it. So I'm going to turn up the capacity to somewhere around 90 something percent. Just gonna paint that dark shadow. And if you look at the lighting, the the light is coming out from the Windows side and you can see the shadow is going in this direction here. So it's actually you want to have anything that is here costing the shadow in this direction, laying on some shadow on the pizza. So I believe the only object is this one here. So I'm going to do a shadow here. And then I'm gonna do a DEM, a shadow that's slightly larger. One mole, we even less opacity. Just to create a nice fade. Ok, I think that looks, that looks all right. Okay. And then you might know about that could be secondary occlusion. So any objects that are close to it would cost a very faint shadow on it. So any object like the hand he had, the plate here and the cop here. So I'm gonna go ahead and add that in as well. So this is just a very faint shadow. I've at about 10% opacity here. Oh, and by the way, if you are wondering what I'm using to create this mask here. Hi, I'm Control clicking, oop, sorry. I'm Control clicking a layer. And it'll select the mask across all of its objects. Okay, great, so that looks like it's blended in. Okay, the mask here could use some improvement. I think this jagged edge is a little bit obvious. So I'm just fix that. There isn't much of a curvature. Here is. Let's go ahead and fix that. Says, Okay, great. And then finally, the last thing is you might notice that the colors don't really fit that well. The room is quite bright and white, maybe even bluish type lighting, whereas this is a very wall yellow type color. So let's go ahead and apply a Adjustment layer and we're going to use photo filter. On this, I'm using alt click to ensure the filter only applies onto the pizza. And we're going to make it a bluish color, possibly a cooling filter. More cyan color. Okay, right. Something like that. And then you'll notice that it's sort of become a bit darker. So we got to the brightness and contrast here. And we're just going to take it up to fit the scene. That looks about good. So I think I'll add a little bit more contrast until the brightness down a little bit. And now should fit in nicely. Okay, so there we have it, we have our result here. I think it looks all right. 8. Outro: I hope you guys have enjoyed this video class. I look forward to seeing some of your creations in the project section, and we'll see you in the next class.
