This is even more handy when used with the file upload procedure described above. The default mode is Auto, which simply uses the flash automatically in low-light situations. Red-Eye Reduction is similar, but flashes several times before the actual flash so the subject's pupils will close down. These mode settings are retained while the camera is off. Fill mode forces the flash on at all times.
None keeps the flash off at all times.
Both of these modes reset to Auto when the camera shuts off. However, reformatting the SmartMedia card will erase all images, including locked images. The word on rec.photo.digital is that the best way to clean the LCD screen is with plain old scotch tape. Press the tape onto the screen and pull it off slowly. The adhesive pulls off all of the grime and fingerprints and leaves no residue.
