Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
In this movie we will be working on the file jenny_kim. This photograph comes to us by a way of one of my friends Jenny Kim. She is a great photographer. Let's go ahead and open this one up by double-clicking it in the Bridge and then press F to go to Full Screen View mode and then press the Spacebar to reposition the image. Now if you have the Eyedropper tool selected, one of the things that you will notice is that I have sampled three different points in this image. We are going to go ahead and remove those samples, but I want to include those with these files, so you can see where I'm going to sample and then I want to talk about it now so that we can do this from Scratch. I also want to point out that I have included a Reference folder. This folder includes the Curves Adjustment that we will make in this movie and I want to include those, so again you just have a reference so you look at, hey, how do Chris actually do that? All right, well, here's what we are going to do. We are going ahead and sample on the forehead here, on the chin and then I want to sample back in here the Shadow because I know that Shadow should be black. So, for the Shadows I'm going to go ahead and nudge those in just a little bit. I'm going to leave those in the RGB values. From my point number 1 that goes to CMYK, point number 2 that goes to CMYK, as well.
All right, so I have the two points on the skin in CMYK. Let's take a look at our numbers. Cyan's low, Magenta wow! Really high, yellow really low again. We have seen this before, right? We have problem here. We have a color shift. We need to correct that and that's what we are going to do. We will click in that Background Layer and then click on the icon to open up the Curves Adjustment panel. Now let's jump right to the Blue- Yellow Channel. Let's do that by a way of shortcut, on the Mac its Option+5, on the PC that's Alt+5. Grab the Target Adjustment tool, hover over one of those points and what we need to do here is, we need to change our percentages, so that we can increase the overall amount of Yellow and I'm looking to get that number just above the Magenta number. So in both cases, now it's just above that. Now how about my Cyan? Well, 3x2 is 6, 5x2 is 10. Well, I'm close to just a little low. Let's go to that channel. It's Option+3 on the Mac/Alt+3 on the PC and then hover over that point, where we are going to look to do, is just to increase the amount of Cyan, just a little bit there. Well, now 3x3 is 9, 3x5 is 15 so between 9 and 15 well, yeah, that looks pretty good.
Well, now, let's look at our RGB values, interesting. Those are almost completely equal. If those three numbers are equal its' telling me that, that Black or that Shadow back there, is neutral and that's great, that's telling me I don't have a color cast in that shadow, well, perfect. Another thing that I'm noticing is that, these values are really low, although I have this light medium tone skin, it's actually quite fair, so again I have a pretty low percentage point my numbers. Now, let's take a look at our over all Before and After, here's Before, okay, well, that doesn't look too good. Here's after. Gosh, that looks so much better. It looks some much more humid, it looks so much more natural and that's what we are going for here. We are learning all of this technical stuff in order to come up with more compelling results. All right, well let's take a look at couple more examples; we will do that in the next few movies.
