grain Anonymous
hay i have a digital cam and i've had it for maybe 2 years but it still works well, but i keep getting grain in almost every shot. I tried cleaning it but I can't do it efficiently or well. This image is one that i took with the camera. The effect and image was what i wanted, but there is obviously really bad grain and it doesnt get the idea across.

1. You mean noise, not grain.
2. Don't shoot at iso400 on a point&shoot camera like that. Keep your ISO as low as possible. That's what's giving you sensor noise.

i was actially fooling arround with the ISO, though i know not what it is. and i get grain on almost ALL my shots, whether the ISO is on 50 or 400.

Yeah, cameras of that class are like that. If you really want noise-free shots, your best bet is to get a digital SLR (but even they get noisy at higher ISOs. Just that ISO800 on a low-end dSLR probably looks about the same as ISO50 on your P&S in terms of noise)
