In my opinion, the optimal "gallery size" that provides professional-grade resolution hinges on the native resolution of the camera (megapixels). Following is a rough rule-of-thumb:
- 8 MP = 11 x 14"
- 6 MP = 8 x 10"
- 5 MP = 6 x 8"
- 4 MP = 5 x 7"
- 3 MP = 5 x 7"
- 2 MP = 4 x 6"
- 1 MP = 2.5 x 3.5"
Based on the human eye, any advantage gained from greater than 8 megapixels is highly elusive ;-)
