Hi,
my goal is to make everything work with my Olympus E-600 camera, which
is a budget version of the E-620. Both have the same sensor as the E-30.
(See http://de.wikipedia.org/wiki/Olympus_E-620 - german)
My first problem is/was that the make of the E-600 was at first
correctly recognized as "OLYMPUS IMAGING CORP." but was shortened to
"OLYMPUS" when opening the image in darkroom mode. This was correlated
with "i don't know this camera" messages (wording was different) from
rawspeed. Adding the camera as identical copy of E-620 made those
messages and the changing of the make in darktable go away. There seems
to be a problem correlated to using libraw and reading the EXIF Make
field, but with the patched rawspeed this doesn't hit me any more.
Since the E-600 and the E-30 have the same sensor, I then tried clones
of the profiled denoise of the E-30. This works like a charm, as expected.
The attached diff show the small changes I made. I've reported the
changes to rawspeed as enhancement in their bug tracker:
http://bugzilla.rawstudio.org/show_bug.cgi?id=596
Cheers,
-jnf
