I've got a Pixma TR4520. For the most part, it does a fairly good job. However, whatever changes I make to my image, it does not print out. I've got an image of the adobe church in Taos. I've tried to lighten it to open the shadow areas, but it doesn't happen. I've let the printer manage the color, Photoshop manage the color, and made changes to the image itself, to no avail! Any help out there, or at least point me in a direction? If you need more info, I would be more than happy to supply it.
Thanks,
MIke
