As the orienteering season opened up with a late to come winter over here, I noticed that when trying to take photos of people running in terrain that's covered in snow, at least partially, the 40D's highlight priority is very convenient. Without me having to think any further than to enable the function, it reduces the blown highlights in the snowy areas significantly.
This is of course as it's expected to be, but it's always interesting to see that it really works too.
