I have this image:
I'm trying to:
1) cut out the napkin
2) make the white more pure
This is what I've done so far using the magic wand to select, white point and curve adjustments
As you can see, the edges of the napkin are overexposed, while the center is still grey-ish.
If I keep using curves to try and fix the grey center, it will make the edges even more exposed in the process. How would I make just the grey part more white?
