In this exercise, I'm going to show you how to load a collection of 14 custom gradients that I've created for you, all of which are conducive to the task of colorizing a black-and-white image using the Gradient Map function. I have gone ahead and saved my changes as Pennies from heaven.psd, an allusion to the fact that we have gone ahead and colorized Big Sky, Montana, using the Copper Gradient that ships along with Photoshop. But I'm going to spoil our fun a little bit by going to the Colorize layer and changing its Blend mode from Color back to Normal, which renders the scene pretty much unidentifiable, because the Copper Gradient isn't designed to work with the Gradient Map function in the first place.
Let's try out some gradients that are. Now, if you have access to the exercise files, then you have this collection of gradients ready and waiting for you. Click the down pointing arrowhead to the right of the Gradient bar, and then click this right pointing arrowhead to bring up this menu of options, and I want you to choose Load Gradients. Next, navigate your way to the 18_black_white folder and click on this file called dekeTones CS5.grd. Then go ahead and load it up, and you'll see a collection of 14 additional gradients.
And what I'd like you to do is just wander through them to get a feeling for what's up. So we've got a Warm palette right here, and all these gradients are pretty strong. In other words, if this is too much color for your image, you would want to go ahead and reduce the Opacity of this Colorize layer. But in the meantime, here's Warm palette, the next door neighbor is Cool palette right there, and then we've got the Sepia palette, which is quite a bit yellower than the Warm palette. Next we have a series of Reflect and Repeat Gradients that create highlights inside of the darkish shadow regions.
So we start off with this guy, Earthtone reflect, which notice creates a series of Green highlights back in the shadow region, and that's something that might work for some images, quite well in fact, but you can always modify any one of these gradients to better suit a specific photograph, and I'll show you how that works. Next we have got Carnival reflect, that goes ahead and throws these purple values into the shadows. After that we have a series of Green and Red, and then we have Blue repeat right here.
And each one of them, not only includes a dark Red, Green, and Blue palette, but also some highlights down there in the shadow regions. So again, you can decide to accept that or overwrite it, you can manipulate every single one of these. Next we have got a fairly crazy one here called X-ray invert, that goes ahead and creates a Green inversion effect. Now, even the inverted effects are useful as regular standard gradient maps. However, you don't have to accept the inversion, you can just go ahead and turn on this reverse check box and then you get a standard Green colorization effect.
But I should say that every single one of these luminance levels has a slightly different combination of Hue and Saturation values associated with it. Even if the image in general has a Greenish tone associated with it, those Greens are varying between Yellowish Greens and Bluish Greens across the board. Anyway, I'm going to turn Reverse off, so we can see the effect of the other gradients. Next we have got, this is pretty extraordinary were this image is concerned here, Complementary VY. And what we are doing here is we are starting with violet shadows and we are ramping our way up to Yellow highlights.
And we've got a series of other complementary gradients; we have got Complementary RC, which starts with some Red shadows and ends up with Cyan highlights. And that we've got this guy, Complementary BO, which stands for by the way Blue Orange. So we are starting with Blue shadows and we end up with Orange highlights. And even if the highlights look a little bit Reddish, that's because we go through Red before we end up getting to Orange, just in case you're wondering what's going on there. Anyway, two more remaining, we've got Earth and sky, which starts off Brown inside the shadows and ends up Bluish inside the highlights.
And then we have got this guy here, Broad sienna, which applies a broad selection of sienna tones across the image. And this one works quite nicely for this particular photograph as well. So anyway, try those out on this image, try them out on your own. You can use them any which way you want. In the next exercise, I'm going to show you how to customize one of these gradients to exactly suit the needs of this particular photograph.
