I cannot condone frequently changing the brightness of the LCD to suit the ambient lighting when you are viewing pictures. It should be set so that in subdued lighting, it reflects what the actual exposure should look like on your monitor. Otherwise it's only useful for framing. You should also learn what conditions "fool" your camera's metering system, and learn how to adjust under those conditions to reduce your need of reviewing shots on the LCD. For instance, both my Finepix 1300/2300 underexpose when confronted with a lot of bright overcast sky, snow, sand or large white objects (my Finepix 2800 isn't affected as much). When I bought the 2800, it's EVF was set incorrectly and some of my first shots with it were improperly exposed, so I have since readjusted it. See my pics, all taken on "Auto" at
For the other cameras, I have learned to preset exposure by pointing the camera at an average brightness subject and holding the shutter button half-pressed.
