Something awesome I found the other day while editing a photo. This is a way you can edit different colors within a photo on Adobe Photoshop. You can change the curve according to the the amount of intensity you want of a certain color in your photo. You can also create a two curves (like a cubic function) or more if you want to be extremely specific about color. On the side it shows your input and output of the "color function". I thought this was super cool because it put the optimization problems we were working on in a different prospective.
