All you need to know about noise

June 2nd, 2007 - 08:04:47 PM:

It's well known that images from digital cameras show higher noise when using higher ISO settings, and that small digicams also show higher noise than DSLRs. As a photographer you can accept this as a fact, but if you're technically interested the following questions may come up:

  • Why is there more noise at higher ISO settings?
  • Why is there more noise with smaller digicams?
  • Why is there more noise with longer exposures?
  • What can be done against noise?
