Image darkens from bottom to top. How can I make it uniform?
Here's what I've got. I rotated it 90 deg so you can see it get brighter from left to right. Do you see how the peaks below get taller from left to right? Is there any way I can make them the same height? To make the brightness (or luma) even across the image? I've tried color curves, hue/sat, feathering with the exposure control on the color board, and the "graduated mask". Nothing works. I can change the relative heights, but can't get all three colors flat. (Just in case someone asks: Yes, I know FCP can do titles, but I need to preserve the look of the original Super 8 film made in the years 1976-1977.) Any ideas?
