Next what I'm going to do is I'm going to take this watermarked piece of paper. I'm going to select all. Edit, copy. Select the top layer of my layer stack and I'll go edit, paste. And what I'll do now is I'll change the blending mode so that it kind of sets a texture over all of these images. So I'll go normal. Let's see what multiply looks like. Looks good but there's a little bit of blue showing up here. Let's see what happens if I go to overlay. Brightens it up a little bit too much. Let's try a color burn. That looks pretty good. So I just want to move this over a little bit. And as you can see, it starts to blend the images together a little bit more.
I also have this wallpaper image here as well, so I'm going to select that as well. Go to select all. Edit, copy. And next what I'll do is I'll go to the Paris layer and I'll say edit, paste. And again I want to select a blending mode that will kind of bring this all together. Multiply is pretty good for this one.
Next what I want to do is I want to really blend these together a little bit more so I'm going to go to an adjustment layer for this. And I'm going to choose levels this time around. And up here in the adjustments palette, we have our levels here. And this triangle refers to the darks. This triangle refers to the midtones. This refers to the highlights. So what I want to do, I think, is adjust my midtones down a little bit. Kind of bring them together and then maybe bring my highlights up just slightly. And it's starting to get a little bit saturated so I'm going to add another adjustment layer.
So the key with these adjustment layers is that they effect the colors of all the layers underneath of them. So I'm going to add another adjustment layer to bring down that saturation. I'll go to adjustment layer, hue, saturation. And for this I'm just going to move the saturation down a little bit. And that starts to bring it all together. And now we have something of a more cohesive image.
And that's how you make collages in Photoshop.
