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.

In this exercise, I'm going to show you how to adjust the luminance level on a color-by-color basis inside of Camera Raw, and what we are going to do is we are going to sink the skies, so we have really moody sky going. We are going to make the grass just this amazing sort of shamrock green, it's going to be a lot of fun. You will see. The image in question is called Tree & shadow.dng again from Chris Orwig. Go ahead and open it up inside of Camera Raw, and let switch over here to the HSL/Grayscale panel, and I'm going to switch over to Luminance for starters because I want to make the sky dark right away, and just see where we standhere.
So I'm going to take this Blue slider and I'm going to move it all the way over to the left, and that the sky becomes incredibly dark, and it is just amazing that you can do this. Just dial it in and you are done. Now I'm not terribly impressed by the transitions, so I wouldn't want to leave it here without any other editing, but it is an interesting start. And then I'll go ahead and take the Purples down and notice that, that's sinking the sky further, so much so, that I'm going to take the Blues up a little bit. I don't need them to be quite that dark. So I might take them up to be about -70, and then I might get some action out of this Magentas slider. It doesn't look like I'm really so, but it's a good idea to protect yourself. You don't want super sudden transitions between one color group and a neighboring color group. So if you kind of split the difference with the neighbors, that's often a good idea, not necessarily but you know.
All right, now let's go over to, let's say Saturation, because I would like to see the saturation come out of this sky a little bit by making the sky so very, very dark, I have kind of blown it out, made it super-duper saturated. So let's go ahead and take that down. This looks pretty good to me. We might not have to go down that far with it, actually though it might give me a little more room to take my Blues slider down to like -75 let's say. All right, that looks great. Now the grass. I want to make it super saturated.
So I'm going to go over to the Saturation value and I'm going to increase the saturation of Green through the roof, and we get a little action out of that, mostly back here in this region is where we are seeing the greens. This grass should just be leaping at this point. It should be so incredibly hyper saturated. Well the reason that it's not getting more saturated and we can see, by the way, if you go to Luminance, you can really see that doing Greens, like increasing the brightness of the Greens is not having a profound effect on the grass. It's having a slight effect but not a super huge effect and the reason is what we think of as foliage in general, so whether it's grass, or whether it's leaves on the trees, or that kind of thing, more often than not, it falls into the yellow zone.
So if you were to brighten the Yellows for example, you are really going to see that green change, or if you darken yellows and you are going to see the grass that is changed as well. All right, I'm not interested in changing the Luminance. I just wanted you to see that. So let's go back over to Saturation, and let's increase the saturation of that grass to something ridiculous like +75, and then we will back up for the greens here a little bit, take them down to about +30. Now I want the greens to be greener, because it is becoming more and more evident, not only because I fooled around with the slider but also because as I'm increasing the Saturation, I can see right there that those do tend to be yellows, or more sort of chartreuse colors at this point.
So let's see if we can them more emerald by going over to Hue and taking the Yellows value all the way over to the right and you can really see things green up when you do that, and it does just turn into shamrockville. All of a sudden we are in and amongst the lucky charm elves. So let's go ahead and back this off just a little bit, maybe back to +50. It looks pretty darn and nice. And just to get a sense of where we went with this image, this is the before version, so this is the original, and this is the after version. Thanks to our over the top modifications, but I'll tell you what, I kind of like them. I got to say and then you could go ahead and Click on Done.
Oh! That is fun to see that happen, and then to really take the image in, I'm going to press the Spacebar here inside the Bridge, so this is the modified tree image, I love it. In the next exercise, I'm going to show you how to generate a custom black and white image inside Camera Raw.
