Default Shutter speed in different situations

hi, im fairly new to photography and im looking for advise with shutter speed for different situations.
- how do you determin what shutter speed is apropiate for different situations.
- whenever you turn up your shutter speed, do you turn up your ISO to compensate for the lighting or is there another option?
- my camera can do up to 1/4000 shutter speed, is that good or bad for a SLR 8 mega pixel camera? (i think that is the correct number, it just says 4000)

sorry for the bad spelling and i apreciate all the help i can get :)

regards Nick

Default Re: Shutter speed in different situations

Hi there Nick. I'm fairly new to photography myself but I'll share what I know. Shutter speed is expressed as a fraction of a second. Most dslr's and even high-end digicams can go as fast as 1/4000 (like yours) and can have as long as several seconds shutter speed. A faster speed will mean less light. The rule of thumb for handheld still shots is to try and keep your speed to a reciprocal of your focal length (to reduce camera shake and picture blur). Thus for a 50mm focal length, the minimum handheld speed would be 1/50. For action shots where you try to stop action (sports, racing, etc.) you will need a faster shutter speed (say minimum of 1/500). It is always better to use a tripod so that shutter speed can be reduced further.

Like I said, shutter speed affects exposure. If you want to increase shutter speed while maintaining the same exposure, then you can either up the ISO or increase the aperture. Changing these other two settings affect more than exposure though. Usually, you get more noise at higher ISOs and less depth-of-field at bigger apertures.

Try searching the web for a good primer on photography (there are many). This topic is simply to big to discuss in this forum.

Hope this helps.
