I opened and old psd-document today, and saw that all the layers suddenly had a weird watermark of multiple points/triangles of transparency all over... embeded directly in each layer so they could not be removed.
Does anyone know what is causing this ?????
I have attached part of the image, to show what I mean...
Watermarks are not like a layer that can be turned off or deleted. Its like drawing with the paintbrush on a layer. So if the only version you have is watermarked and there is no history you can revert to, then the only way to get rid of it is the same way you'd get rid of the paintbrush drawing: use the clone stamp.
