Proper use of auto exposure

[John.McWaters]

Is highlight compression still necessary when auto exposure is enabled? I'm wondering what the proper technique would be for using the new auto exposure.

Highlight Compression and exposure are two different things. Exposure uniformly lowers the brightness of everything. Highlight Compression only affects highlights. I don't think there is any "proper way" of using those two. Highlight Compression should be used to adjust final appearance of the renders just like most other tone mapping operators.
