The variations command allows you to change selected pixels or all the pixels in your image based on shadows, midtones and highlights. It is located under our image menu under adjustments and all the way on the bottom variations. The dialog box presents you with your current pick, this is the untouched image as, as it is so far because we haven't done anything yet and this is our original. Whenever we uh apply an adjustment for example we can click darker a couple of times down here we see that our current pick gets darker. If you decide that you don't want this uh change click on original again to go back to the beginning. As you can see here we can change shadows, mid tones, highlights, saturation and with each of these settings we can see that we can show clipping or hide clipping. And what we can also do is determine whether we are going to have fine selection or a coarse selection and as you see here the coarse will allow you to get some very posterized effects. So let's go ahead and talk about how we are going to use this dialog box. First of all I'll go ahead and just select midtones, I'll choose darker and I'll click OK. Now she has a nice tan and all the midtones in the image are nice and dark. Let's go ahead and undo do that to see the difference. Let's return to the dialog box this time we are going to apply some very extreme changes. So I'm gonna go to highlights and I'm gonna hit more blue quite a few times. And look at the difference between our original and our current pick. Let's go ahead and accept that as you see here we have this interesting effect because we just changed all of the specific pixels. I'm gonna undo this and this time I'm going to select some pixels in the image. So I'm gonna use the quick select tool and just grab a part of the image here. That tool is unbelievable I still can't get over that. And as soon as I get this arm here I'm going to go to variations and show you that you can affect only selected pixels as well. So once again image, adjustments, variations and this time I'm gonna go to the midtones and I'm going to go to the original here and I'm going to add more green. Now click OK, now as you can see here you can make like the hulk so if you want to pose in the mirror and make some muscles what you can do is color yourself green using variations and change the pixels while retaining all of the shading and highlight information in the image.
