    According to DPReview...

    They then go on to say this...

    Do any of you use this? If so, all the time, or in what situations?

    I use it as default. Honestly I can't tell the difference, as the instruction said, the effect is subtle. You only really notice it when you fire up the DPP and the Highlight slider does next to nothing to your pics. When I used my G10, which has no HTP, moving the Highlight slider would visibly change the pic.

    I see... if you process RAW in something other than DPP, will the pic looked underexposed by one stop with HTP?

    Yeah, sorta, but in a weird way. Its kind of the antithesis to ETTR, if you subscribe to that way of thinking.

    So how HTP works is that it "cheats you out of" using ISO 100 (e.g. the native ISO for Canon sensors), then underexposes the whole shot to "protect" against blown whites, then boosts the blacks in software with some (non-linear) unpublished value for the curve. Its the "boosts the blacks in software" that leads to noise, IME, and is why I stopped using HTP for landscapes after one trip. That, and the fact that I hate the UI for DPP...
