No - it's been available for as long as I can remember. It's
probably using DCRaw to read the files.
Several other image viewers can also open DNG\PEF. I prefer XnView
or Faststone to Irfanview, but there's not much between them. I
think they all convert the raw files to 8 bit colour, so they have
limited use for raw conversion.
Wow! It blows my mind that I'm just now learning this. IrfanView gets
along much better with Photoshop .8BF plugins than GIMP does -- at
least in my experience, and there are a lot of PS plugins I like to
use. Unfortunately, GIMP doesn't handle .PEF and .DNG without using
another plugin (like UFRaw), and it really doesn't seem to like using
that in conjunction with the .8BF plugins.
But, with IrfanView, I can use PS plugins to manipulate RAW files and
then send them to UFRaw to convert them to 16-bit .jpeg. And any
editing from that point I can do in either GIMP or Picasa, as needed.
So, this is kind of a big deal for me -- which probably says more
about my life than is prudent to reveal, but there you have it.
Yes - but you're throwing away data in doing that, aren't you?
Irfanview will take the 16 bit raw and convert it to 8 bit. Sending
to UFRaw and converting back to 16 bit wont recover what IrfanView
lost and then GIMP will process the file in 8 bit anyway (as far as I
know it still doesn't have 16 bit support).
Ah -- I was under the impression that IrfanView could open 16-bit files,
but just down-sampled them upon saving. I guess it down-samples them
when it opens them instead. I thought you could run plug-ins, etc. and
it would manipulate them as a 16-bit editor, then send it to UFRaw to
save it without losing data.
I think I'd be working the other way. Use UFRaw\GIMP to process the
raw data then save in 8 bit TIF to use your plugins in Irfanview.
But maybe I'm not visualizing your workflow properly.
No, you have it right. I was just mistaken and filled with a false sense
of hope that I'd finally gotten a leg up.
