Automatic HDR from a T3i?

[thereyougo!13 1]

Instead of bracketing, you could always just shoot in RAW which will give you greater control over adjustment. Shoot one image then adjust in post (-2 exp, 0 exp, +2 exp) and stitch.....

This is far from ideal, although I have done it myself - if you process it well, you can get away with it. Process it badly and you can end up with a lifeless shot

It's not... simple, but it also gives you a ton of other features, like long exposure times, time-lapse snaps, and motion-detection! Unified - Magic Lantern Firmware Wiki
