Hi Brooke:

Rather than create a long OT thread on SeeSat, I will make this my last post on this subject.

Thanks for sharing that dynamic range expansion technique. Although I have had good results with my Nikon D70, I do not like the overall color palette and color rendition (especially of dawn/dusk skies). With regards to the newer Nikon DSLRs in general, the images look electronic/over-processed. The Canon DSLRs seem to produce more pleasing images.

For what it's worth, here are a few links to space-related images taken with my D70:

Brian Webb
