I partake in bus photography for a hobby, and I take new images out of the originals so that there is a closer picture of the bus, cutting out unnecessary things in the picture, such as traffic lights or people.
When saving some of the new images, I find that there are black and white lines on the top of the picture, and the originals aren't around anymore. Is there anyway to remove the lines and restore the image to it's former glory?
Thanks.
