We have digital cameras today that that just keeping increasing on the megapixels but is that the only thing that can be done to improve picture clarity? More megapixels relates to larger image size, which means you have to pay more for higher capacity memory cards.I have seen pictures taken by a 3 megapixel camera, which was blown up to a poster that was about 4ftX3ft and the clarity was pretty good. May be more megapixel translates into better digital zoom, which has cheaper manufacturing cost compared to the manufacturing cost of optical zoom. Ironically I have notice that the low cost cameras have a low optical zoom as well as low megapixels translating to low digital zoom as well. It begins to look more like a marketing strategy for digital cameras than anything else.
