[QUOTE="WolfHeart, post: 714393, member: 47173"] I opened 240 images as layers in Photoshop from Lightroom after basic editing and started from the bottom layer up applying lighten blend mode and masking out any unwanted light streaks till the top layer. when I apply merge layers/merge visible layers/Flatten a weird geometric circular pattern appears across the image on the sky and foreground. I reset my images in Lightroom as I read that lens distortion and sharpening can cause this and to do the adjustments after merging, so images are dngs straight from camera, when I merged them the pattern appeared again but was more uniform like a checkerboard. I tried another set of 30 images and same patter appeared. Does anyone have a solution for this? I have attached an image after merging, you can see the pattern clearly in the highlight area of the image. I also tried exporting jpg and using startrails software, got same results. any ideas?
