How to Use AE Lock With Hold

[stevet1]

I ran across a web site from Canon explaining how to Hold your AE Lock. See here:

AE LOCK WITH HOLD 

I know I can Lock my exposure by pressing the * button, and then Hold my AE Lock on my T8i by pressing and holding either my AF On button or my Depth of Field Preview button. The Hold lasts for as long as I keep pressing that button.  If  I release that button, the Hold disappears after the standard six seconds. With newer models, you apparently can maintain that Hold for as long as 30 minutes.

I like that feature because you can meter off one part of a scene, and then swing your camera around and take your time to recompose, like for doing silhouettes.

Hi Steve,

I'm a fan of AE-lock with hold for several reasons. When I photograph motorsports on a track I use AE-lock with hold to meter from the track - a handy mid tone in most cases. Doing this the exposure for the following frames are consistent regardless of the colour of the body work on the car. Without AE-lock with hold a black car would lighten the exposure, a white or silver one darken it. For circuit racing you often get a few moments while the cars are out of view to recheck the exposure before the cars appear again.

Brian,

I like it because I'm slow on the uptake, and it takes me a couple of minutes to get the composition right. 😃
