Re: how many mSec between frames without flipping the mirror?
2009/5/14 Larry Colen l...@red4est.com: I'm not looking for tonemapping. Last night I was trying to shoot the sunset while overlooking the Santa Clara Valley. I could expose on the sky, or on the valley, but not both. It is a perfect case of where two shots, several stop apart, shot in the same fraction of a second would be the perfect solution. I suppose that I could try bracketing and post processing, but it would be very handy to have it in the camera, and to have the two frames close enough in time, without camera jiggle, to hand hold. I believed that combining different exposures to a single photograph, compressing the total tonal range into something renderable on a computer screen/print, was what tonemapping was all about? Shouldn't matter where the processing takes place as far as I can see...

how many mSec between frames without flipping the mirror?
It seems to me that it should be possible to expand dynamic range by firing off two (or three) frames on the same shutter press. It wouldn't work for sports, but for many shots even the motion in 1/5 second (assuming 5 FPS) would be acceptable. If the mirror is the limiting factor, maybe 1/50 second rather thant 1/5 second between frames would be doable. Especially since a lot of the time when I have rough dynamic range issues, I'm already shooting at something like 1/10 second, so two frames of 1/10 second and 1/80 or 1/160 second would be a good match, and the stutter between the two frames would be negligable compared with the blur. -- The fastest way to get your question answered on the net is to post the wrong answer.

Electronic control of the shutter independent of the mirror is probably easier to implement than mechanical control.

Nor does the K20 when in Burst Mode.

Re: how many mSec between frames without flipping the mirror?
The simple way to do this is to lock the mirror with an electromagnet once it has swung up and then release when complete. There was a range of electromagnetic leaf shutters developed in the sixties that used a completely mechanical action to fire the shutter, but an electromagnet to vary the delay between opening and closing the shutter. The fastest one I have is accurate to 1/250 sec with the top speed, 1/500, being purely mechanical. You probably wouldn't even need a new timing circuit, just a turn this on when in burst mode and a don't release mirror until shutter button released subroutine.

It is very likely deemed not worth the investment. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
