Your camera will set the ppi to a recommended value but it is really not relavent at all.. the only thing that matters is your photo size which is 2816x2122.. once you are ready to print or save for web.. then the DPI comes into play.. ppi could be set to 72 and it wouldn't matter.. so basically is doesn't matter - just be sure you don't resample your image with the ppi set to 72...

While not well written.. the info here is quite accurate and may help you understand.. http://www.graphic-design.com/Photos...esolution.html

Good Luck!
