ISO film speed equivalence

The International Standards Organization (ISO) measures light sensitivity, which traditional film photographers use. In a digital camera, photographers have the option of doubling or having light sensitivity around basic values. This value usually runs around 100 ISO. Higher values come in cameras that let photographers adjust the CCD sensitivity for low lighting situations.
Try: Jeff Salvage uses Two Feet Gallery.com to express a variety of ways to use ISO settings to create specific shots. He discusses speed settings for deliberate blur shots, as well as shots that intentionally reduce noise.

Scene modes

Scene modes are settings on a digital camera specific to certain activities and lighting. This includes photography for sports, night-time photographs, close-ups, portraits and landscapes.
