Flash functions include two automatic modes (one with, one without Red-Eye Reduction) where the camera senses the light level and fires the flash accordingly. In using Red-Eye Reduction, the flash pre-fires a second or so before the Flash exposure, causing the subject's pupils to contract, thus greatly reducing the red-eye effect. click for bigger image click for bigger image All the pictures in this issue were shot using an ISO 100-speed colour slide film. In the camera's instruction manual, Canon recommended to use the camera with ISO 400 film for best results since the zoom lens' maximum apertures of f/4.2-/8.7 does not always provide sufficient flash coverage when using the camera's built-in flash indoor. The Prima Zoom 85 also has a Forced flash mode function that allows you to use the flash even in bright light conditions -- especially useful when your subject is illuminated from behind. This feature allows you to fill-in the shadow area of backlighted subjects. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 .
