Megapixels directly relates to file
size, but in terms of color channels. The primary colors that are directly
related to digital photography are Red, Green & Blue (RGB), with each color
assigned its own channel. So, when you are told you have a camera that renders
a 6 megapixel file that each color channel is assigned approximately six
million pixels. But how does this relate to the digital file your camera
produces? To determine the approximate size of a files take the number of
megapixels and multiply by 3 (once for each color channel) and you will arrive at the approximage full size file. The reason I state approximage size is that each camera has different size and quality sensors that factor into the file size.
When push comes to shove you need to determine how large
you plan to make prints and then determine how many megapixels the camera you
plan to purchase must have. At Larmon,
you will find our consultants knowledgeable and helpful when it comes to
assisting you determine your needs.
