If the subject is stationary and you want maximum clarity, choose the settings with the smallest aperture (to increase depth of field).

ISO Speed and Exposure ISO affects the shutter speed / aperture combinations you can use to obtain correct exposure ISO measures the sensitivity of the image sensor Higher ISO settings are generally used in darker situations to get faster shutter speeds (for example an indoor sports event when you want to freeze the action in lower light) If there is not enough light you can increase the ISO setting this can be done automatically or manually ISO settings in the Canon A460 are Auto, High,
