Hi Andy,
DPI doesn't really mean anything in terms of the image file sitting on your computer or on the camera. It's simply a ratio between the image and the printer, which determines how high of a resolution it will print at. It is technically called PPI (pixels per inch) rather than DPI (dots per inch) when talking about digital images.
You can set the DPI setting to whatever you want in Photoshop and it won't affect the quality of the image on the computer. What it WILL affect is how large the image prints out. Try changing one of your photos from 72 to 300 ppi in photoshop and watch the "print size" fields change. :]
72 PPI will produce a much larger print, because at 72 PPI you're only putting 72x72 pixels (5814) into each square inch, rather than 300x300 (90,000).
Hope this helps!
