The marketing hype for digital cameras always stresses how many megapixels a camera has, the usual “bigger is better” sort of argument.
Thanks to a gizmodo article, I now understand that all pixels are not created equally. It seems that small cameras and mobile phones likely have small pixels and the bigger digital single lens reflex (DSLR) camera have bigger pixels. Bigger pixels are able to more accurately capture and display colors. Less bigger pixels will probably yield a better digital image than more smaller pixels.
I’ll take this logic to explain why my zilla-pixel mobile phone camera doesn’t take a better picture than my slightly elderly Canon Rebel XT DSLR.
