For indoor photos using a flash, overcast exterior shots and everyday snapshots. ISO 400 Best for action photography, low light photography such as evening shots. ISO 800 Can be used in most lighting conditions, for action and sport events, low light shooting. ISO 1000 For fast action shots, and artistic portraiture.
