Hi Steven,
It’s been ages, I know, but did you ever find a 3-way corrector for Photoshop?
I’m doing some adjustments on a load of photos, and it would save a lot of time having the basics in one window.
Reading this thread, I was a little astounded at the hostility of what seemed a pretty useful query. After Effects and Premiere have this feature, can’t see why Photoshop having it wouldn’t be helpful, even if it was just to accommodate ‘inexperienced, novice’ users who just happen to be more used to grading software. Yes you can do a million things with amazing accuracy in Photoshop, but compared to grading you have to go through ten windows to adjust every value individually. If a simple screen allowing you to intuitively change the majority of key luma & chroma values is a blunderbus, then not stocking blunderbusses in the world’s largest gun shop is just stupid and snooty.
Could do this in AE or Premiere to save time, just seems a bit foolish to be photo editing in a video package.
Did you find any plugins, or is there is similar tool in CS6?
