Exposure Mode Controls Auto (point & shoot) Program Shutter priority Aperture priority Manual setting
Auto Mode: When you want to take snapshots without worrying about the mechanics of photography, put the camera on Auto. This mode sets all exposure levels automatically, and it usually locks you out of making any minor adjustments manually. This is for general picture taking.
SCN: Exposure and White Balance is selected to match the picture you are taking.
Flash Modes You will not have control over the flash in all modes on your camera. In Auto, the camera usually will only allow AUTO FLASH (the camera decides when to flash) or FLASH OFF (no flash at all). One of the best flash modes is FLASH ON…which will allow your camera to flash even if it doesn’t think it needs it. If you subject is close, it will fill in shadows, etc.
Resolution Setting Resolution and Compression determine the total image quality. Some cameras may not allow you to change the compression. Always shoot at the highest resolution…you can always make it smaller.
ISO Selection Ability to vary “film speed” for lighting conditions ISO 50 ISO 400 Canon G1is first digital to offer ISO 50
Understanding ISO Just because your camera CAN shoot at HIGH ISO, doesn’t mean you should. Generally, try to stay one stop lower than the maximum ISO. Example: If your camera’s max ISO is 800…don’t go above 400. Don’t use Auto ISO. Nikon D200 ISO 1600Nikon D300 ISO 1600
