A 6x4" print at an optimum resolution of 300dpi will be made up of (6 × 300) × (4 × 300) = 2,160,000 dots: just a touch over 2 megapixels. However, to print at a perfectly acceptable 240dpi we only need (6 × 240) × (4 × 240) = 1,382,400 pixels. Result: a 2mp camera should produce great 6×4" prints! Share. Improve this answer.

It’s generally good enough if you feed it enough light, but image quality falls apart as it darkens, especially in areas away from the point of focus – no surprise there at this price. In a lot of instances, you’ll find that recording at even just 7fps is enough to capture almost anything moving at a standard rate of speed. Unless you’re looking for an extraordinary amount of detail in a quickly moving object, there is nothing wrong with recording at 1 to 15 frames per second.
