Gradient map editor sliders have no effect
I am trying to recreate the effect in the attached video. The sliders on the gradient map editor do not have any adjustment affect on the image. .Moving them back and forth does nothing...Any of the gradients also do nothing...Photoshop is up to date running Windows 10 (updated) I have tried a few things yet no results....Any chance it could be a video card issue as mine is an older NVidia card and it also doesn't support the Oil Paint Filter. All the other adjustments on the adjustment panel work fine.
