I've been shooting with a 20D for the last year or so and have begun printing imagery via large format inkjet. I just realized that I am seeing a consistant purple tweak in images that are shot with extended exposures in lower light conditions and in other instances where the subject matter is fairly cointrasty. The purple appears as shading that follows the transition from moderate to deep shadow into midtone.
This issues shows up consistantly and once you see it it's pretty annoying.
Wanted to see if anyone else is experiencing this issue.
