K200D D-Range Feature

Do any of you use the D-Range feature on your K200Ds? Or any other camera? I have had my camera for a couple of years now and was recently reading back over the dpreview on the K200D just for fun and came across the paragraph on the D-Range feature. According to dpreview, D-Range really helped preserve some details in the highlights of a contrasty photo. But the review wasn't clear about what exactly it is doing and also didnt mention anything about whether shooting RAW vs. jpeg had anything to do with it. I usually shoot RAW and convert in ACR......does it make sense for me to use the D-Range feature when i shoot in RAW? I am usually a stickler about keeping my ISO as low as possible, and D-Range forces me to use ISO 200 as a minimum. This is not ideal in noise regards, but if it extends my dynamic range enough to warrant it, I may consider using it more often. I work a lot, so often I only get to go out shooting in on lunch breaks or after work and this usually means I run in to a lot of high contrast scenarios. I hate clipped highlights so if I can avoid this effectivly while shooting RAW, I'm interested.

Please post any of your comments/advice on the D-Range feature. I did a search through the forum, but it turned up mostly convoluted discussion that didn't really answer my questions or shed much light.

Any help is much appreciated.

P.S......off subject....I'm a new member, so I guess this can me by introduction post. Very glad to be here. I've been a reader for a couple of months now and really enjoy it. I've learned a lot and this forum is the reason I decided to stick it out with Pentax even though all of my friends shoot Canikon and share lenses with each other. I decided to suck it up and take pride in the fact that I am in a rare group of photographers. To signify my decision to stay with the brand, I just ordered my first prime lens (SMCP-FA 50mm f/1.4) and couldnt be happier about it.

Thanks for the help...I look forward to being more invloved in the forum.

Hi Mcc
Finished the ALCS an filling in time till the WS? First answer is simple... no effect on a RAW file at all. Think of it an adjustment to response curve used to develop that raw file into a jpeg in the camera itself... probably as you are doing yourself in ACR. (ie pushing it up at the bottom)

Thanks, Col.....exactly what I needed to know. I'll be avoiding the D-range from now on.

Haha.....yes I am.....but I'll be glued to the TV for every game of the World Series. Can't wait to see my Rangers dominate the Giants. I just wish i could make it to a game to take some pics......standing-room-only tickets are $450 though.....that'd be a nice lens or two so I'll pass

Thanks again.

This wont affect RAW, only JPG. Its just a correction curve that compresses the dynamic range of your image into a fake sort of HDR.
