Sorry, my bad. Of course the screen pattern forms moiré patterns as well, but the plugin will fix them as they're part of them screen pattern. Other patterns that are part of the image are not affected.akovia wrote:Not sure what you mean by before they happen, but that is indeed moire. I believe that is halftone moire specifically, which gimp handles also just fine. Unfortunately it takes 20 times as long as your plugin.
It won't fix the moiré patterns that occur when you shrink an image with a screen pattern or scan it with too little resolution. Like this one: https://picload.org/image/wiwdrlo/moire2.jpg (side note: I had to use nearest neighbour interpolation to produce the pattern. Bicubic would have smoothed it out so much, there would hardly be any moire left)
Crushing shadows and highlights sure can fix some problems, but I didn't see anything in your image that would have called for it. If it weren't for the horrible moiré (which you were able to smooth out nicely) and the clipped highlights, I wouldn't consider it a bad picture at all.akovia wrote:Yes of course. When dealing with a picture this bad you don't have a lot of options and crushing the blacks hides a LOT of problems. If you have a better solution I'm all ears.ZincRider wrote: I notice both of you really crushed the shadows, which increases the contrast and makes the colors pop, but unfortunately it eliminates the difference in color between the dark fabrics and darker shadows..
