What is the best way to obtain usable ISO800 images?
ISO800 allows for proper exposure at higher shutter speeds to help freeze the action and/or avoid seeing the effects of camera shake in your pictures, perhaps in low light situations. However, it also means much more noise in pictures than there is at lower ISO speeds. Here are some tips for getting usable ISO800 pics: • Only use ISO800 when you have to. • Avoid getting the camera any hotter than necessary. • Do not underexpose. • Shoot soft (set sharpness to soft) and sharpen later during post-processing on a computer. • Consider shooting at a lower resolution like 1600×1200. • Use a noise reduction program like Neat Image or Noise Ninja on a computer. Most of these ideas are considered together in this useful article by Bryan Biggers (Shooting ISO 800 on the DiMAGE 7). The lower resolution will be fine for web-based purposes, but will be limiting if you want to print large.
