I have placed a greyscale TIF on a spread. When I place another PNG image on the same spread, the brightness of the previously placed graphic appears to change. The graphic appears more bright/less dark (see below). Pay attention to the graphic on the right and watch how it brightens up once the PNG is placed.
My questions are: Does anyone know why this is happening / what is happening? Is this only effecting the way things appear within InDesign or is it going effect the print?
