Photoshop is one of the world’s most powerful image editors, and it can be daunting to try to use skillfully. Photoshop CS4 One-on-One: Advanced, the second part of the popular and comprehensive series, follows internationally renowned Photoshop guru Deke McClelland as he dives into the workings of Photoshop. He explores such digital-age wonders as the Levels and Curves commands, edge-detection filters, advanced compositing techniques, vector-based text, the Liquify filter, and Camera Raw. Deke also teaches tried-and-true methods for sharpening details, smoothing over wrinkles and imperfections, and enhancing colors without harming the original image. Exercise files accompany the course.

All right, I'm still working inside Black & white comp.psd. I didn't really do anything to this file. I just kind of played with the Tint value, that's it. So it's up-to-date, if you've skipped the last exercise, no problems, because this is the good exercise anyway. This one is about how you infuse an image with lustrous color, of course false color, but I mean we are trying to achieve a sepia tone for example, so that we get the entire dynamic range available to us when we print our monochrome image. So we are effectively creating what's called a Duo Tone, which is a monochrome image infused with color, and we are going to do that using a Gradient Map adjustment layer. So here is how. We want to go ahead and apply the adjustment layer on top of B&W. If we put it below, then B&W would make it monochrome again, so we won't get any colorization out of it.
So make sure B&W is active, it's the active layer, then click on the left pointing green arrowhead right there, and then what I want you to do is click on this gradient right there, that is the Gradient Map function. Actually I'll Alt+Click on it or Option+Click on the Mac, and I'm going to call it sepiatone, and then I'll click OK in order to create the new layer, and there it is. What Photoshop is doing is it's just taking what was previously a black and white image, and it's assigning a black and white gradient to it. So everything that was black previously is now black, it's mapped to the left side of the gradient here to the beginning of the gradient, and everything that was formally white is now white mapped to the end of the gradient, the last color in the gradient, on the right side here, and everything in between is mapped to different shades of gray in between.
So this is what the image looks like without that layer, and this is what the image looks like with that layer. Now if for some reason this is looking a little bit colorful to you, if you are seeing a little bit of color in your video, that's just a function of our compression. It really, what you want to see is just absolutely black and white, just different distribution, just higher contrast, because of this gradient bar right there. But if we want to add color, we need to select a colorful gradient. For example, if I click the down pointing arrowhead I can choose from one of Photoshop's default gradients. Like for example, this dandy gradient right there, Violet Orange, which goes ahead and makes the shadows violet and the highlights orange, and that's it, and I could do something crazy like reverse it, so that we get this inverted effect there if we wanted.
So I'll just go ahead and turn off that checkbox. What I really want is some better gradients to work with. None of these are really all that useful for creating Duo Tones. So I'm going to click the right pointing arrowhead, wouldn't you know I have given you some gradients to work with? Then go ahead and click Load Gradients, and that brings up the Load dialog box. Now find your way to the 16_adjust_ layers folder, and then you will find this guy right here A few good grads, you want to go ahead and click on it and load it on up. And you will see a variety of different duo tones gradients that you can choose from. I'll click on this first one, Quadtone Deluxe, Quadtone just means that we are working with four color altogether as opposed to two which is what duo tones implies, but duo tones is an overarching term for duo tones, and tri tones and quad tones, and I don't know if there are quint tones, things that have five colors in them for example.
Let's try out these various gradients here, here's the one palette. Nice that looks cool. Here is this crazy green one that makes the darkest colors, the shadows greens, and it works nicely for some images, but not so nice for this one. This is another crazy guy right there, he is called Carnival reflect. I used to use this image of a little dummy doll that was in a carnival. So that's where some of these names come from. Like this guy right here, what's it called Green man, because he was a man, but it works just as well for people of the other gender. And this one is Wooden boy. We'll come to it in a second, because that's what we are going to use. And then we have got X-ray inverts that produces this cool effect here, but of course they can all invert if you want them to, but just turning on Reverse here. And then if you wanted uninvert, X-ray invert, you turn on Reverse too.
Anyway, here's where we are going to start. I want you to select this one, Wooden boy, which works just great for girls too. So I'm going to apply it, but I want to modify the settings, I'm not entirely happy with what I'm seeing here. So I want to modify my colors, and you'll see not only can you introduce different colors if you want to, but you can move where the colors are located, how the colors map to the luminance levels in order to correct the luminance on the fly, and I'll show you how that works, it's a beautiful thing, in the next exercise.
