It's a flat and beautiful universe. I always model it. The original data was covered. I can't flatten the background. If I use the affinity photo tool, it will turn black. Raw data gives me various trials.
Hi. Affinity Photo's 'Remove Background' tool works well. It will darken the background sky almost to black but you can recover the neutralised sky background by moving the bottom slider, 'Output Black Level' to the right. Move this just enough to bring back the image details but not the colour caste in the sky background.
Another very good tool for smoothing uneven backgrounds and gradients is the plug-in for Affinity and Photoshop, 'Gradient Xterminator'. 👍
