Hi /p/, I was hoping you could help me with a relatively basic camera question. I've recently started to carry around my older point and shoot digital camera around with me to work so I can take pictures during my commute. However, I've noticed that they are coming out somewhat grainy when I view them at actual size (3.2MP) on my computer.

Is there any way to prevent this on a point and shoot camera? It's about three years old and I don't think it's ever been cleaned either...is that possible at all?

Thanks in advance from a bit of a photo newb

your camera may be set to use a higher iso. look through the settings and see if you can lower the iso or put it on a lower speed auto iso or whatever. youll need longer exposure times with lower isos, but they will come out less grainy if thats what the problem is.

I've usually been using it on auto iso, but i started to notice the grainy quality of pictures while taking pictures at an indoor garden. i suppose i should have changed it from auto in retrospect, but i would have thought the camera would have compensated for the lighting (it was quite ample, and flash was prohibited)

The camera *is* compensating for the lighting. By raising your ISO, which increases the sensor noise (especially on small P&S sensors like yours).

What looks like ample lighting to your eyes often isn't to your camera.

ah ok, thanks. next time i head out i'll remember to use manual and take several pictures rather than just 2 or 3 on the same setting
