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.

ist-D multi-exposure (was:Re: My first *ist D gallery)
- Original Message - From: Rob Studdert [EMAIL PROTECTED] BTW who has actually seriously used the multi-exposure function beyond tests? My sister gave me the National Geographic Digital Photography Field Guide. In it the author, Rob Sheppard, describes how to use two exposures of the same scene to expose for the highlights and shadows more effectively. Obviously, a tripod and static subject are necessary. I have not tried it, but intend to at some point. Christian

Hi Christian, Making multiple exposures to capture a wider dynamic range is a good idea but the integrated function multiple exposure function won't do you any good in that case. Just set the camera to auto-bracket a couple of stops and record the discrete frames and meld them in Photoshop later. I will dig up a link to a great web site about the subject that I found some time back, I just can't find it now.

Re: ist-D multi-exposure (was:Re: My first *ist D gallery)
Although not necessarily related to increasing dynamic range, here are a couple of links to an interesting program. I've not tried this particular one, but their PT Assembler is good. http://www.tawbaware.com/maxlyons/cgi-bin/image.pl?gallery=8 http://www.tawbaware.com/imgstack.htm Bill - Original Message - From: Rob Studdert [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, January 06, 2004 10:19 AM Subject: Re: ist-D multi-exposure (was:Re: My first *ist D gallery) On 6 Jan 2004 at 8:52, Christian wrote: My sister gave me the National Geographic Digital Photography Field Guide.

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.
