So, were going to see what happens when we use this. If we go to window, or actually if we go to view, I'm sorry, and you hit gamut warning, you're going to see that our grass is over saturated like crazy, and that was my guess. So, what I want to do is actually go down to our saturation, under our adjustment layer. As you can tell I'm right here, click on that and hit hue saturation. Now what you want do is, you want to go to your edit menu, right there, and click green. Now, our picker got unlock, so now we want to click the plus sign. Click right in the gray area, I'm going to click right there one time, and now it sampled that gray. Now, what we want to do is drop our saturation until all that goes away. O.k., now all of that is away. Maybe boost it just a little bit, now we'll make it go away. O.k., so now it's all the way, all the grass. O.k., hit o.k., and let's throw a little bit in there actually, so I'm going to go back to my saturation, go back to greens, go back to my picker, pick exactly where the gray is, real small amount. Make it all go away, o.k., now it's all the way, as you can tell, hit o.k. So, now we are for sure that our image will print correctly, so now were going to actually merge down. So, if you remember, and it's not giving us the option to merge down, so were actually going to leave it like it is, and we?re going to merge all the layers together, and were going to do that here on the next clip."
