Where can I get a few high resolution pics to try my new printer?

Re: What camera are you using?

OP & Gesture,

you both seem a bit missinformed...

1. Printers output is in DPI. Each printer has fixed choices for DPI, For example epsons have 360, 720, 1440 and 2880 DPI settings. More dots = higher quality image, but slower printing. It takes a matrix (2 dimensional array) of dots to represent 1 pixel.

2. Printers input is in PPI (pixels per inch). 300 PPI is considered photo quality. Newspaper print is closer to 72ppi...

3. The actual picture is in X by Y pixels in size. It can be printed at any ppi that you choose; this choice will in turn determine the size on the paper. There is a tag in the jpg files which specify ppi and in turn that will specify printed size, however these labels are optional and you do not have to print at the PPI listed in the file.

1. D800 is the first camera with resolution so high that it simply does not matter.
2. Most people who do not own/shoot d800 missunderstand it. Color depth and accuracy in addition to resolution is what makes d800 great. Resolution alone is over rated.
