I have a studio shot (attached) that I need to extended the background to the left and right.
I’ve already duplicated a section of the existing background and stretched it. This created some dirty vertical banding so then used a mix of Gaussian Blur and Surface blur to try and blend the colours together. But then this created some nasty blocks of colour because there wasn’t enough colour values to smooth out the graduations. So I then applied a little Noise to try and break up the banding.
The end result is passable but not great.
Can anyone suggest good techniques for retouching graduations like this, particularly of studio backdrops. I noticed if I go in to the individual RBG channels, in the extended areas of the background, the channels are very mucky and full of artifacts.
