Canon EOS 33 - AE Lock; Locking Exposure Settings

*AELock
With the same focusing point, you can obtain and lock the auto exposure
setting on one part of the picture and then recompose to focus a different
part of the picture. AE lock enables you to maintain the same exposure
setting even after recomposing the shot. This is effective for backlit subjects.
• Also see ‘AE Lock Effect" on page 92 to see how AE lock works
