Buying a Digital Camera Look for ISO 50 Support SUMMARY: Look for digital cameras with ISO 50 support for crisper, cleaner images.   While most digital cameras have ISO 100 as their lowest ISO setting, if you are looking for even crisper, clearer photos when you have lots of outdoor or artificial light, consider purchasing a digital camera that supports ISO 50. Pictures with this setting have even less grain (noise) than ISO 100 photos, but they will require lots of light otherwise the image will be underexposed. Also, due to the extended exposure times, you will mostly likely need to use a tripod or other stabilizing device.   Add: Del.icio.us | Digg | Furl | My Yahoo!   Discuss This Tip Print This Tip Get E-Mail When New Tips are Online Return to the Buying a Digital Camera page.
