It works best under changing conditions when you are in a hurry. It decreases the need for clever light metering, exposure compensation and variations to the picture style in order to handle situations where exposure and contrast (too much or too little) makes photography a bit more difficult than the average.

You can achieve the same by shooting in RAW and fiddling with your pictures in post processing, and sometimes by thinking more before you shoot, which implies more careful metering (perhaps even multispot) and testing a few shots, to see how they come out.

But if you can't afford that kind of working method, but just need images that are reasonable in the blink of an eye, then try ALO. According to Canon, it was implemented as an answer to requests from sports photo journalists, who wanted useful images quicker than their competitors, and jpegs, so they could be sent electronically in a reasonable way. In order to make it to the frontpages faster than anybody else's photos, of course.

I tried ALO. It works when you need it. It gets in the way if you have it turned on when you don't need it. Sometimes hugely. I got tired of turning ALO on/off. Putting it on your MYMENU can help. All it does is boost exposure in the shadows by adding +EC, then bringing down the highlights. You'll get better results shooting raw, +1 (depending) EC, and pulling down the highlights in post, if necessary. ALO ruined more shots when it was on and not needed than it ever helped with.


Dedicated APS-c shooter. Gripped 60D, 60 2.8, 10-22, 15-85, Σ70-200 OS and a big white something or other! Plus a 5D w/28-75.

Thanks. I've often wondered what ALO did.
