First decide you output size. Lets take an 8x10 picture with a camera that has 1600x1200 pixels. If you want 150 dpi you have a picture that is 1600/150= 10.6" 1200/150= 8" so the picture is slightly cropped. 150 to 200 dpi is enough resolution to print on an inkjet printer even if the printer says it is 720 or 1400 dpi
