+But consider that you also need light for all those pixels - meaning many a 5 MP camera actually is no better than a 4 MP camera due to too small a lens.

+If you want to print at 300 dpi, you're bound to get decent results if you use the following formular
+Size of Image = Pixels / 300.
+
+In reality, if people keep within the 'optimal viewing distance' you need no more than 1.5 MP for *any image* to look sharp.
+Alas, as soon as you tell people 'I made this with my digital camera' they tend to bump the picture into their nose.
+And if you want to enlarge parts of images, you obviously need more pixels. +
