Iso

I always leave mine on Auto, when or if should I alter it. Choices on my Sony P71 are Auto, 100, 200 and 400. Know I'll get a better answer here than in the manual

The higher the number, the more likely you will get an shot without blur in low-light conditions.

However, the trade off is a grainy "Noise" over the image in certain circumstances.

Go read my night time article for more info =)

I quote...

ISO
Film ISO is a measure of how sensitive to light it is. A higher number means the film is more sensitive to light and will therefore catch more of it quickly. The trade off is Digital or Film Noise, which you can read about it that section of this article.
For detailed information, see: en.wikipedia/wiki/Film_speed

Out in the parks, using a higher ISO setting will help get pictures where you need to hand-hold the camera.

If you are taking a static shot, then the lowest ISO setting you can use will most often give the best result. As always, experiment to see what works best with your camera.

Most cameras will only let you change the ISO setting if you are in its Program Mode rather than the fully Fully Automatic mode.

Try ISO 400 as a starting point for hand-held photography, and 800-1600 in really dark situations.

If you are on a tripod, set the ISO as low as possible for most shots, 100-200 is my usual starting point.

It's worth noting for DSLR owners who may chance upon this thread, that the size of the sensor in the camera is a factor in how an high an ISO setting you can use without too much noise.

A full-frame 35mm sensor such as that in the "Canon 1ds-mk2" will out perform a "Canon 10d" with it's smaller sensor at higher ISO's for this reason alone.
