I can get the same effect and better in the RAW converter and with fewer drawbacks. While HTP may prevent clipping caused by inexpert metering, it can just as well cause a waste of unutilized headroom and a subsequent loss of DR. Meanwhile, at the other end of the tonal range, by increasing shadow noise it raises the noise floor and thus entails a further loss of DR. HTP is like setting your watch 15 minutes ahead of time in order to be punctual, a crutch for the inexperienced and insecure. Like the Jpg format itself, it is designed for those for whom "good" is good enough and going for "very good" is too risky. Elie / אלי

Certainly better than HTP, from what I have read. Considering the extra noise in the shadows, I have it turned off. In fact, I've never had it turned on. Bohdan - I may be, and probably am, completely wrong.
