Recently I've been using Apple's color grading software, Color. It utilizes 3 way color corrector wheels, contrast bars and curves to fine tune the color and contrast of video clips. I really love being able to use the scopes that it features, which allow me to ensure that I have pure blacks and pure whites in my images, to have my optimum contrast (not too high, not too low, just perfect 0-100 range of tonal values). I'm wondering if Photoshop has this feature or if there are any plugins I could find. It seems like a simple enough tool, and would really come in handy for my photo editing. If anybody knows, I would really appreciate some help!
