I have NO idea what is happening here - it is just very strange. This photo was taken through a flyscreen looking down onto shops. All OK. Then I tried to edit them - the lines shown by the screens - on the same photo!! - changed as I did various edits!! Enlarging or diminishing the image made them change - but then when you saved the result and reopened it they looked the same. I made this collage by saving the images as screen shots at various enlargements. It seems to be something to do with the pixels - but I have no idea what!! If anybody has any suggestions I would really appreciate it!!
@dkbarnett Thanks Delwyn - I wonder if the small checks are doing the same thing as the small squares in the flyscreen. It must have some sort of physics or electronics explanation - just wish I knew what it was!! :)
@bintal Hi Sylvia - It is interesting - I thought it did give it a bit of a surreal look. It's interesting to read about it - Casablanca told us it's a Moire pattern.
@casablanca Hi Casablanca - thanks so much for the info and it was very interesting to read up on it. The changing distance between the pixels as you magnify etc explains the changing pattern. Just fascinating. Cheers Rob
