Yesterday evening, I charged the batteries for an old point and shoot digital camera I've had for several years - a Nikon Coolpix something or other. It has a 1mp sensor. I made a test shot on the "fine" setting which is the full resolution mode. Windows tells me the JPEG is about 660kb in size. When I bring the image into Photoshop, it says the image is 8 mb. RAW files from my 6mp DSLR are only 6MB. I don't understand what I am seeing.
