I have a digital camera. I notice that my photo quality is not what it use to be. I am thinking it is my memory card. It's a San Disk SD . 1.0 GB. I have had the camera new since Jan. 2006 not top of the line but not bottom either. HP Photosmart 6.2 Megapixels. I have taken a few hundred photos with it and the memory card. I delete the photos off the memory card after I upload my photo to the computer. My question to any one who knows is.... Can the memory card lose it's Quality? The card is not the top of line ( I would guess bottom for a 1 GB card) Should I upgrade my card?
