Enclosed please find the picture that I printed with different options. Since I take pictures in the snow, white on white is a problem. There are white DVDs, white bookcase and white walls.

I used sRGB and Adobe RGB from the camera, no enhancement, iPhoto auto enhancement and Adobe Photoshop CS Auto levels, and printed them with Apple Color Sync, or Epson Standard Gamma 1.8, or Epson Vivid Gamma 1.8. After looking at all the combinations (having written how they were done on the back of the prints), the winner was Canon sRGB with no enhancement printed with Apple ColorSync on my Epson R800! That's not the result I was expecting.
