Re: ist-D multi-exposure (was:Re: My first *ist D gallery)
yes, i bought Optipix after looking around some. i never tried HDRShop, but from looking at the program specs, i would say that it is doing something different, which is allow processing of images and not lose the shadow detail because of not enough bits per pixel. Optipix allows me to capture more range than the sensor is capable of by shooting series of images at different exposures and then blending them into a single image. one of the recommendations for Optipix is that they sell a $1000 image manipulation set of plugins for really exotic scientific digital image processing of the kind that i used to study when i was in school. image blending is a lot easier than what they do in their high end package.

Re: My first *ist D gallery
Very nice photos! Neutral colour, very good exposure. Ah, and you are lucky - you have summer in Oz now, we have -10 degrees here in Poland :-) What I like about *istD pictures, that they are slightly film like with natural colours and tones. -- Best Regards Sylwek
Re: My first *ist D gallery
Rob, I remember when you did the same with your newly acquired Olympus. By then I disliked the huge dof / nasty boke of the macro shots and in general the video look. Now it definitely looks better. More natural, more film like. Good luck with your *istd. Servus, Alin Rob wrote: RS Comments and unbridled criticism welcome. RS http://www.home.aone.net.au/audiobias/wildflowers/
Re: My first *ist D gallery
I did some nature shooting recently with the *ist D and I find that I agree with most of Robb's assessment of how this camera handles. Some points to note: 1. I'm not as bother by the lack of aperture ring and have actually adjusted quite well to this. OTOH, I'm right-handed. 2. The idea about replacing the rocker switch with distinct buttons (5?) is a good one. It's way too easy to rock it the wrong way. 3. I never select AF points. To me, it is always quicker to use the central sensor and recompose. Picking a different sensor just takes too long. When I have to shoot very quickly, i.e., when AF is necessary for me, I go to the auto mode and let the camera choose. It generally does a good job, and the hit rate is probably faster than my MF attempts would be.

Although not necessarily related to increasing dynamic range, here are a couple of links to an interesting program.

I'm not as bother by the lack of aperture ring and have actually adjusted quite well to this. OTOH, I'm right-handed. I'm left-handed (and left-eyed), but have no problems operating the thumbwheel with the camera in shooting position. 2. The idea about replacing the rocker switch with distinct buttons (5?) is a good one. It's way too easy to rock it the wrong way. Or, at least, make it larger. That, plus having to take the camera out of shooting mode to adjust the ISO, are my biggest annoyances. 3. I never select AF points. To me, it is always quicker to use the central sensor and recompose. Picking a different sensor just takes too long. When I have to shoot very quickly, i.e., when AF is necessary for me, I go to the auto mode and let the camera choose. It generally does a good job, and the hit rate is probably faster than my MF attempts would be. One of the reasons I wanted the *ist-D was for the ability to select an auto-focus point below the midline of the frame - just what you need for motorsports shots with the car approaching you. I don't know if the multi-point AF will track a car heading in your direction at 200mph or more, but if it doesn't then I want to be able to pick the right point. I've got a couple of shots (taken with the PZ-1p) wher the driver's head is in focus, but the nose of the car could be a little sharper.

Re: ist-D multi-exposure (was:Re: My first *ist D gallery)
you don't use the multiple exposure function for doing this. you need two separate image files. i have done up to 6 files taken one stop apart blended to get deep shapow and bright sunlight within range.
