Hey all,
So I bought a canon powershot a95 a while back and have been really happy with the results but lately I've been getting noise showing up in some of my pictures, I'm not really sure whats causing it, i'm a noob on digital cameras and photography in general, but I have noticed that after messing with some settings the noise goes away but then it reappears and I have no idea what the settings are that changed it so any help would be greatly appreciated.
thanks

One of the biggest noise contributors in digital cameras is high ISO settings. On my A95, ISO of 200 and especially 400 introduces noticeable noise (random colored pixels in what should be a solid colored area of a photo). This is not unlike grain in high ASA/ISO film. You can reduce the ISO to 50 or 100 to get rid of the noise, but then you're more prone to get blur from subject movement or camera shake. It's all a compromise.
