I'm certainly not looking for a big burst, just 2-3 frames. > But you know, I really don't know the tech magic anyway.

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. > > Jostein > > 2009/5/14 Joseph McAllister <[email protected]>: > > Nor does the K20 when in Burst Mode. > > > > When shooting in RAW, you should be able to get HDR from a single shot in > > post by creating two or three versions from the RAW data, each taking > > advantage of the limits of the RAW data high and low, then combining them > > using Photoshops HDR. > > > > Have you tried the HDR Digital Filter in the K20 yet?
