Re: SV: Better K10D exposure-tests (Was:*ist-Ds Vs. K10D image quality?)
Personally, I've tried several different sets of ACR calibrations for the *ist DS and K10D that people have posted here and elsewhere ... and all of them produced results as default starting points for color balance that were farther off the mark than just opening the DNG file and setting white balance with the eyedropper tool. Lightroom's white balance adjustment works even better. It's great when you have a definitive reference for white, but caused me no end of trouble with my recent Cormorant cock-up 8) Eventually selecting as shot for the starting point, some of the other default settings seem way off the mark, such as daylight, cloudy and shade!!!? The eyedropper in Capture One Pro seems to do a better job, but no support for K10D yet, I'm saving my one free upgrade for that :) On the flip side, Capture One has a real dogs dinner of a GUI but I guess it's a case of RTFM 8) John The information transmitted is intended only for the person to whom it is addressed and may contain confidential and/or privileged material.

That makes sense. In any case, I do intend to try the calibration. I bookmarked your reference page.

The key to getting a good white balance is to find and sample a light gray area, not a white area...

But the technique isn't limited to Camera Raw ... I use the same in Lightroom and in Photoshop on RGB images using a Layers Adjustment Layer with the sampler tools. For the latter, I set up samplers on target areas with a 5x5 sampling, then use the grayscale eyedropper after the white point and black point droppers. I doubt you have to re-install anything, though. Finding the *right* gray spot to sample is the trick. ;-) G -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

I prefer to use a Zone VIII gray, about 60% gray reflectance. OK, now I'm getting somewhere. I've had less than 300 shutter releases using RAW, most were in a controlled environment (testing lenses etc) where I've shot film over some 16 years, it was easy to adjust the white balance there, now I'm just getting adjusted with my first few outdoor shots, thanks for the help.

Adobe Camera Raw. Personally, I've tried several different sets of ACR calibrations for the *ist DS and K10D that people have posted here and elsewhere ... and all of them produced results as default starting points for color balance that were farther off the mark than just opening the DNG file and setting white balance with the eyedropper tool. Lightroom's white balance adjustment works even better. I don't think that calibration is a waste of time, however. I just haven't found anyone's calibration that works better than what is offered as a default. It's so easy to adjust color balances when dealing with RAW format data I don't know why there's so much fuss about it. G On Feb 12, 2007, at 8:06 AM, Jens Bladt wrote: What is ACR, Rob?

That's one of the reasons I had a tendency of deliberately underexposing, to totally avoid over exposed parts of the images. Thje K10D does not add a reddish cast to the very bright parts. My conclusion is that the image quality of K10D images are in fact superior, compared to the quality of a similar *ist D image. Lots of issues I had with the *ist D rendering went away after I calibrated ACR to the camera. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
