Is that a CS2 only thing?
It seems strange that one can go back a couple of generations in PS and
things work.
Maybe it's CS2 that's the problem? I think that version was a bit
squirrely.
Anyway, running the original Pentax DNG files through the converter
isn't necessarily a bad idea: The early Pentax cameras that offered
DNG raw didn't compress the files. Running them through the converter
saves disc space (and also smaller files equate to quicker backup
times). Even my K5 DNG files are smaller after going through the Adobe
DNG converter.
I'm pretty sure Adobe Camera Raw was originally an extra cost plugin for
Photoshop 7.0 that Adobe made a free download about the same time they
introduced their DNG converter. The *ist-D was not supported by the
first version ACR. Support for the *ist-D wasn't added until version 2.3
or 2.4 of ACR.
I started out with Photoshop 5.0 LE that I got with my Nikon scanner.
Photoshop 5.0 LE was not upgradable, so I purchased Photoshop 7.0 from
Amazon while I was in Iraq & it wouldn't open Pentax *ist-D PEF files.
I had to convert *ist-D files into JPEG or TIFF files using the bundled
Pentax software or set .TIF as my "raw" format in the *ist-D.
When I got back stateside, I bought PhotoshopCS & started using .PEF as
my raw format.
By then PhotoshopCS was almost at the end of its life cycle. CS2 came
out within a couple weeks of my purchasing CS. When I registered my
product Adobe gave me a free upgrade to CS2.
I don't remember doing anything with DNG files at the time. I stuck with
.PEF files even after I got the K10D. ACR in CS2 & CS3 both handled .PEF
files with no problems.
I'm not sure what version of Photoshop I was using when I decided to
convert to using .DNG files as my raw format.
