Subtitles of the Movie
At the bottom of the Image menu>Adjust submenu, there is an item called Variations. And what this does is, it brings up interface which graphically shows you how you would manipulate the different colors, primaries and their complementary colors. At the very top, we have two images. This is our original, and this is our edited image. Currently we have made no edits, so these images are exactly the same. To the right of these two pictures are four different radio buttons. We can choose to edit the shadows, midtones, highlights, or the saturation. So I am going to work on the shadows, and also notice that some of these images have bright colors in them. This bright pink. That is called the clipping, and what that means is that, if you choose to use this particular variation, that the colors that will be generated by it will be outside of the printable gamut. You can disable Show Clipping by clicking this checkbox. So if you want to add more green to the shadows, you would click this big picture right here, and notice how my image updates slightly. We could also add more blue. I go to the midtones and we might want to add a little more red to the midtones, and finally the highlights. I will take away some blue by adding some yellow. You can choose how dramatic you want these effects to be by moving this slider from fine to coarse. If we go all the way up to coarse, notice how dramatic the changes are between the different encircling images. So this gives you an idea (in a graphical way) how different colors, primaries and complementary colors can work. So you can make these edits from very coarse to very fine. Now if you look at our original image, it is noticeably different than the current pick. If you want to cancel this current pick, you can always click Cancel or Reset, or you could also simply click on the original image and replace it. Of course I have to start all over again. We can also choose if we want our image to be lighter or darker, and if we dial up and down coarse, you can see that there is a dramatic difference here. And I think I will go for the middle value and make it a little bit darker. And finally work a little bit on the saturation; I think the saturation is pretty good, so I am not going to edit that. And of course we could save these settings, should we need to make this same edit on a series of pictures. For instance if a series of pictures were distorted from a film type, or a scanner gave a series of pictures a certain cast, you'd want to save out these edits. And then you could open variations and load that saved edit and run it on each image. So I will click OK to apply the change, and here is the edit and here is what it looked like we ran variations. So it is a little bit different.
