HDR in post always appears better than the in camera function. HOWEVER, it sure is nice to have a rough HDR preview jpg to determine if the exposures were correct and to chimp a bit.
Agree on this, for me as an amateur and also completely new in HDR it is a good way for me to learn. I think in general some people wants to dismiss features that they think belong in the amateur space instead of actually embracing them. While learning this, I have played with it together with my children using the crazy modes you can get from it and found it opens my creativity, teaching me what can be done which leads to that I want to do it better myself, also the children will see more of the fun that one can have with cameras.Unfortunately, automatically implemented HDR features aren't of interest to me in their current state. I need the raw files.
That's exactly what the 5DIII does. It saves all the original RAW files plus a JPEG preview rendering in your choice of a few styles (including a not-hideous "Natural" mode that avoids excessive tone-mapping).
And, as I mentioned, it does this at six frames per second.
It's also got a pretty extensive auto-bracket mode that does the same thing but without the JPEG rendering.
Exactly. There's a slight confusion on how this is done. Yes, you can shoot your 3 shots and have the camera produce a 4th shot that is the HDR JPEG. But you can also do HDR in post with your 3 original RAW files. This is the exact same thing with Multi-Exposure mode. So to say the JPEG feature is a downside is actually wrong. It'll give you a free JPEG of all 3 shots and if you don't like it, you can do your own HDR image in post.
