So listen, I just started to work with camera and I don't understand in Pixels and Resolution. What are Megapixels and what influence do they have on resolution? Yea, and also what is the point of Many megapixels?I have Sony HDR-SR10 and it has an AVCHD resolution (1920x1080) and its only 4.0
megapixels. what the point in more megapixels like 5,6,7? Why do sellphones have them? What effect does it all have?
