Ask the Teaboy

Q:How much resolution do I need to look for in a digital camera?

A: The easiest way to answer this would be to turn the question around and ask you "How large do you ever anticipate wanting to print your images?" Statistically, 96% of people never print their images larger than the standard 6x4" size. For this size you only need 2 megapixels of resolution. Having said that, if you want some cropping flexibility, or wish to make the occasional 8x10" enlargement, then a 3 or 4mp camera would be better for you.

The resolution question is one we're asked daily. Over the last 3 years the resolution available has increased dramatically, and we are actually getting to the point where, for most people, the resolution available is exceeding need. We now have 5, 6, and 8 megapixel consumer cameras, as well as even higher resolutions for some of the professional units.

Q: Is having more resolution than I need a bad thing?

A: It can be. Higher resolution means bigger file sizes, which translates to more and larger memory cards required, as well as computers with greater processing power and hard drive space.

Although some professionals will still be seeking greater resolution so they can sell those enormous wall-sized images for advertising, the average man on the street may well have more than he needs available today.
