Exposure Lock

Hello. I was just curious - is there a way to do an exposure lock for the T3i when working in manual mode? Or does it only work in shutter/aperture priority? Thank you in advance!

I think there is no exposure lock on Manual Mode. 🙂

Is there really an exposure lock in Manual Mode ?

Nope. Meter for what you are wanting to expose properly then adjust your settings to get the exposure you want. There's no lock because you are adjusting the settings based on what you are metering. There's no lock for the same reason there isn't exposure compensation in manual mode.

I wonder if that isn't a little too facile. There's no exposure lock because there's nothing to lock; you're already setting it manually. But you can't make the same argument about exposure compensation. If the camera's meter consistently misreads the brightness of the scene, it will tell you to use an erroneous setting. Exposure compensation would spare you from having to remember to make the adjustment each time.

"There's no exposure lock because there's nothing to lock; ..."

Yes sir!

In a sense of the word, it is "locked". It will not change unless you change it. Right?
