Hope this helps!
FE Lock; Flash Exposure Lock.sumball said:I would say FE lock will lock your setting such as speed, aperture. i.e. it wont change though the lighting condition has changed when u recompose your shot.
Correct me if I am wrong. ;p

dkw said:According to what I understand, when you look through the viewfinder, prior to triggering the shutter, the lens aperture is actually wide open to allow in maximum light for you to compose the shot and AF to work. This is regardless of whatever aperture setting you use. Try it, stop down the aperture while looking through the viewfinder. If the aperture is stopping down, the image will get darker and darker (it doesn't!). When you trigger the shutter, the aperture will now assume the size you set, the mirror is lifted and shutter opens. By pressing the DOF preview button, the aperture will stop down to your setting, and allow you to visualise the amount of DOF available for that particular setting. Given the small VF on the 300D, I have found this feature next to useless, though somebody on this forum may be able to give you some ideas how to use it fruitfully.
Comments/corrections welcome.

When you take a flash shot, the flash will meter from the entire scene. If the scene is predominantly black or predominantly white (eg typical wedding dinner scene), the metering will be thrown off. FEL will cause the flash to take a reading from the point either under the the centre area or active AF point - it is up to the photographer to choose wisely which point to meter the flash. Camera assumes the point chosen is middle tone and will adjust the output of the flash *for that chosen point*.
