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.
Welcome to the chapter on color management. Color management is a pretty hot topic these days, and rightly so. Color is fascinating and color is tricky. One of the reasons that color is so important is because color makes us feel certain things. It makes us think certain things and I love color. That's one of my favorite things about photography. So what's the deal with color management? What's it all about? Well, color management is about trying to clear up the communication between your different devices. For example, it's about trying to clear up the communication between your monitor and your printer, so that the color you see on your monitor is actually that color that you get out of your printer. Well how does this actually work? Well, let's go ahead and talk about color spaces for a moment. Let's say that we have these different color spaces and here is what actually happens.
I'll simplify the process a little bit. Let's say we are in Adobe RGB color space and there's a red color in our image. We will call that Red 3. Now that Red 3 in order to be printed actually needs to go through this translation process. Again, I'm oversimplifying this a bit but I'm oversimplifying it so that I think you'll catch the drift of what's happening. So that Red 3 all of a sudden becomes a one to go to the LAB color space. So now it's a Red 1. Well then Red 1 becomes a Red 6 in order for the printer to actually print it, so that what we see on our monitor, let's call that Red 3, when it's printed it's actually Red 6. So we can't just send Red 3 to the printer because it won't look very good, because they are speaking different languages, there are different color spaces.
Now why is that? You would think can't we figure this out by now? Well, the main reason is because on your monitor color is created via light, and on your printer color is created via ink. There are two very different color models. So we need some translation along that process. Color management helps with that translation process, so that our different devices can communicate "the same language," and so that we can have consistent color across multiple devices. Well, let's take on this topic a little bit more and we'll do that in the next few movies.
