This may seem like a stupid question, but does anyone know about the life of memory cards?

I have been comparing pics from when mine was new compared to recent shots. I see a pretty big difference. The newer shots seem less sharp and more grainy.

Is it just me?

if a memory card was going bad, it wouldn't reduce image quality. Remember, these are digital, not analog. If a card is bad, it simply will stop functioning properly.

Actually no one knows yet. The first ones are still working. Like csb said, they either work or they don't. If you see a degrigation in image quality the first thing to check is your camera. Your HP has two speed settings, ISO 100 and 200. If by accident it's set on 200 you'd see more grain and the image would appear less sharp. Could also be any in camera sharpening or tone settings that might have gotten disturbed, or maybe the resolution/quality settings.

Is that saying that the higher the ISO the more grain??

Yeah, it's like film. The higher ISO films will typically have more grain than the slow ones. In digital, when you 'turn up the volume' on the sensor you get more noise, especially on flat surfaces like walls and clear sky. It appears like colored dots like in a Serraut (?) painting. There are techniques in Photoshop that'll remove most of it, and some of the newer cameras have noise reduction circuitry of one kind or another.

I will double check these things and see if it makes a difference. I think there is some kind of problem with my camera. Perhaps it was wishful thinking that is was something easy like the memory card.

Well, that's what he gets for using ISO-800 canvases!
