70D auto light optimizer only affects jpgs right?

ALO is effectively disabled for RAW? How about Hightlight Priority?

ALO does not affect RAW file data, only the embedded JPEG. HTP does affect RAW file data.

As a RAW shooter, I ignore a good portion of these type of settings. It simplifies matters making these decisions after the fact, and for me, a much better way to work.

Up to a point. If you use the embedded JPEG to review images then it is quite a good idea to choose settings that make it as useful as possible, even if the RAW data is what will be used back at the ranch.. For me, ALO is not something I use, but I do apply an appropriate level of in-camera sharpening so as to be able to assess focus accuracy as easily as possible. HTP is a different matter, since it does affect the RAW data, and I use it when needed.

I'm the complete opposite.  I have the JPEG settings such that the histogram best represents the actual RAW file histogram. This requires turning many of hte settings to their minimums, meaning the JPEG would actually look terrible.  A good looking JPEG will give you clipping blinkies and a maxed histogram with a full stop of RAW headroom remaining. I look at the JPEG for framing only.

No, you are completely the same, in the sense that you choose settings o make the JPEG as useful as possible to you. I said nothing about making it good-looking.

Re: 70D auto light optimizer only affects jpgs right? Depends.

If you use Canon's DPP then opening a RAW file where ALO was on the image displayed will have ALO applied, you can turn it off or adjust the amount within DPP.

Opening the file in any other RAW converter and there will be no ALO applied to the image.
