How many of you wedding photographers use the high light priority setting in the Mark III? I always use it with no exception.

Just turned it on over the past few weeks after taking about 6k shots without it. And I have to say I'm quite pleased with it so have left it on.

Doesn't do anything I can't do myself with photoshop (and with more control over the result too) so I leave it off.

edit - using 40D not Mark III.

It's nice in daytime with good light but introduces more noise in the shadow areas which becomes a problem shooting ISO800 and up. As I usually wind up shooting ISO800 and up, I never use it. Thanks for the reminder though, I might play around with it.

Doesn't do anything of value for you if you shoot RAW so I don't bother.

I use it sparsely when I need a quick, unedited jpg.

Can you explain me that? I thought the high light priority setting prevents the highlights (like the white wedding dress) of overexposure. Why is there no benefit, if I shoot raw? If you turn this setting off, you can shoot even more then ISO 3200, H. At weddings I mostly shoot ISO 3200, and i love the files out if the Mark III. They are just amazing. Very very low noise.

The latitude of "recovery" in RAW from the 1DmkIII is amazing. Using the recovery slider in RAW with any other tweaks can give you more flexability in PP without introducing any more unwanted noise.

The way HTP works is that the camera underexposes the shot by a stop. Then it applies a new tone curve which boosts the shadows of the image while keeping highlight data intact. This tone curve gets applied when its converted to JPG. If you shoot RAW, the camera still underexposes by a stop, it then marks that HTP was set in the RAW file. If you open the file in DPP, the same tone curve that is applied in the body gets applied. If you open the file in ACR, ACR just boosts the exposure by a stop. Thomas Knoll claims this is the right thing to do, you can read about it here:

So essentially you can do the same thing by underexposing the shot by a stop (or how much ever you want) yourself and applying whatever tone curve you want.

Given how much highlight room there is with modern cameras and RAW, you don't really need to underexpose anymore to hold a dress, not done it ever since the 5D and now with the new dodge and burn tools in ACR/LR it really isn't necessary, expose for the midtones/light shadows and use the tools to work everything else otherwise you get more noise and less detail.
