Camera Quality and Noise
Often times on the message boards someone will ask the question 'Is my camera up to the task of capturing quality stock images?'. One of the many things to consider when buying any sort of camera equipment for use in shooting images for resale is, of course how the camera itself handles the issue of noise. Many think that purchasing a small fixed lens consumer point and shoot with 7 or more Mega-pixels of resolution ,rather than a digital SLR, is sufficient to produce quality images. But the number of megapixels is just one facet of a much larger issue when it comes to successfully avoiding noise; and in the case of smaller sensor sizes, can in fact end up contributing to the generation of more noise.
The following web article on noise discusses in very simple and clear terms what noise is, how it is generated and how your equipment quality and sensor size (as well as individual photo sensor size) is important in avoiding noise during initial capture.
