Well, a whole lot of stock photography images are about 18MB in size... here the minimum requirement is 48MB, that's what I mean with 'heavy requirements'. If you should interpolate that filesize to the actual camera pixelsize, without upsizing, you would need at least a 17 megapixel camera..!! That sounds really professional, to say the least....
