- [Instructor] There are several different ways that we can apply cross process effects in Photoshop. It just really depends on how much control you want over the colors and the luminosity values, and how much they change in an image. So we're gonna take a look at two ways. The first way, I want to combine both of these layers into a smart object, so I'll hold down the command key, select them both on the layers panel, right click, and then choose convert to smart object. Now that they're a smart object, I can apply camera raw as a filter to both of these layers at one time, non-destructively.
So I'll choose camera raw as a filter. I can take this to black and white by clicking black and white as my treatment in the basic panel. Then, I'll move to split toning, and it really depends on the story that you're trying to tell with your images, as to what colors you select. For example, I could add a nice, warm red, as well as a nice yellow in the image, if I want this to look kind of warm and happy, for example. But in this case, I actually want to add some cool tones, so I'm going to hold down the option key as I move my hue slider over to the right here, in order to select a blue color, and then I'm really going to increase the saturation.
You'll notice though that it's not increasing the saturation in my mid-tones and that's because my balance is set so far over. If I wanted to introduce blue in my mid-tones I could just move the balance to the left, but I want to move it almost all the way to the right, maybe 65 or 70 so I'm just getting the blue in the darker areas of my image. And then I'm going to leave my hue for my highlights set to yellow, and I'm going to decrease the saturation there. So I'm just adding a little bit of color contrast between my shadows and my highlight area.
Alright, I'll click okay and that's one way that we can quickly apply a cross process or a split tone effect to this image. But there's another way I can do this using an adjustment layer that's going to have a lot more control. So I'm going to use the keyboard shortcut command J in order to duplicate this smart object. And then I'm going to click on the camera raw filter and just drag it to the trash in the layers panel. Then I'm going to hold the spacebar to temporarily access the hand tool and just reposition this so we can see both of the images.
Now in this case I wouldn't necessarily have had to convert the image to a smart object because I could just add the adjustment layer on top of both layers and it would have effect them equally but I might as well leave it as a smart object now because I've already converted it. So at the bottom of the layers panel, I will add a curves adjustment layer, but before I start making adjustments to the curve I only want this curve to effect the colors in my image. So I'm going to change the blend mode from normal to color.
Then I'll make my layers panel a little bit smaller and in the properties panel I'll start adjusting not the overall curve, or the composite curve, the RGB curve, but instead I'll go into the different channels, red, green, and blue. So let's start in the red channel, and I'm going to decrease the amount of red in my shadows by pulling down on the curve and that's introducing this cyan cast. I'm going to lift the highlights in the red in order to add a little bit of red in the highlight area of my image.
Then I'll move to greens. I'm going to decrease the greens in the shadow, this is just going to add a little bit of magenta in that shadow taking that cyan a little bit more towards blue or purple. And then I'm going to increase the amount of green in the highlights, which is kind of negating a little bit of the red that we just introduced with the red adjustment, but it's really the interaction of all three of these that's going to make the effect. So I'll switch to the blue channel, and here I'm just going to lift the bottom of the curve up to introduce additional blue in the shadows and I'm going to take the top of the curve and just drop it down a bit so we get a little bit more yellow here in the highlights.
Now if I toggle the visibility of this curves adjustments layer on and off, we can see that I've definitely changed color but I haven't changed any of the luminosity values. So in order to do that I'm going to add a secondary curves adjustment layer, but this time I'm going to change the blend mode to luminosity because I don't want it to effect any of the color values. I've got the colors the way I want them, I just want to add some contrast. So to add contrast I'll create an S-curve by just pulling down my shadows and increasing my highlight values.
And we can see I don't get any shift in color here like I normally would if this was set to normal mode. By setting it to luminosity, it's only going to change the luminosity values in the image. So there you go. Two different ways to create a split tone or a cross process effect depending on how much control you want over the tonal range and the colors that you're effecting.
