Re: [Gimp-user] Problem importing raw Minolta and Sony files

2014-04-05 Thread Partha Bagchi 
I admit I missed your previous image and so apologies I don't know what
Darktable shows.

When I processed in UFRaw (version 0.20, my build and part of my Gimp build
for Windows 64-bit), It looks fine. I set the exposure to -1.48,
White-balance to Daylight.

If I play a little more with the curves, I get results similar to Photoshop
CC with ACR 8.3. So, I don't think you are missing anything.

I did process in Gimp 2.9 with UFRaw 16-bit.

Hope that helps.

The jpg images look very much like what you see in the Darktable images
provided on the webpage.

Antonio Montagnani and Patrick Shanahan also provided feedback regarding
loading my test image into UFRaw.  Thank you all for the valuable feedback.
I admit to certainly not being well versed in using UFRaw and appreciate all
the pointers being provided.

One thing I had missed before but do see now, is a warning symbol next
to the white balance button.  This does not appear for the Minolta .mrw
images but seems to always display for the Sony .arw files.  When you hover
over it, it states "Cannot use camera white balance."  That is why Auto is
being selected in place of "Daylight".  It makes me wonder what other raw
file data is not being processed by UFRaw for these types of files?  And I
wonder if there is something particularly amiss with the Ubuntu build of
UFRaw on my system?  When others load the sample file, are you seeing a
better image than the one I have posted, prior to making any corrections?
When you load other types of raw images, does UFRaw display them close to
the accurate (i.e., camera) settings?  If so, what version of UFRaw and what
type of system/OS are you using?

Thanks again for all the valuable help.

Looks like a normal image when opened here (fbsd, ufraw 0.19.2).
Underexposed, but can be brought up to 1.49 w/out any overexposure
blinkies.  Clouds have lots of definition.  WB (Camera WB) looks fine.
A little *tiny* bit of purple fringing; I'd be delighted if all
mine had that little.

You don't have the color profile, gamma, and linearity set to something
strange, do you?  If I set to no profile, gamma=0.45, linearity 0.1
all looks good.

Can you also put the jpg you shot since that tells me what you are
expecting to see?

As an aside you may want to visit Dave Coffin's page and read the FAQ
especially about gamma and linearity.

Sure.  Let's use the clouds photo since it is a more modern Sony format and
pretty dramatically shows the loss of information.  Point your browser here:

and save the image.  This is a 24-Mb image file taken with an Alpha a77

Thanks for looking at this.  Let me know if I can provide any additional

Can you provide an example image to confirm this?

Thanks,

It's true that the lion image imported into UFRaw is terribly over exposed,
but that is something that UFRaw is doing to the raw data.  The original
image has proper exposure which was confirmed at the time the picture was
shot as well as the proper exposure from the companion JPEG image (I shoot
RAW+JPG).  In UFRaw the histogram is shoved completely to the right edge
of the spectrum and there is no way to use this tool to fix the picture as
most of the image detail is already lost.  When I open the same file in the
DiMAGE Image Viewer software from Minolta (on a Windows XP machine), the
raw image looks just fine and can be tweaked.

So I have to assume that this is a serious bug in UFRaw and I have reported
it as such.  I'm just confused that I have not heard other people complaining
about this problem.

Re: [Gimp-user] Problem importing raw Minolta and Sony files

2014-04-05 Thread Alexander Rabtchevich 
When you look at an imported image in darktable without applying any 
corrections, the program shows you the embedded preview, which was made 
by the camera itself with all the corrections it (the camera) would made 
with the original RAW when converting it to jpg. If you applyin UFRaw a 
camera curve, similar to the one in darktable, you will see the similar 
result...

After opening in UFRaw, the initial settings are so bad that I am unable to

Are other Minolta/Sony users seeing similar results, and don't Cannon, Nikon

Hello.

Darktable applies RGB camera curve, uses "enhanced" camera color matrix 
and applies a little sharpening by default.

I reported on this a long while ago and then got very busy with other
things.  This is a follow-up with details.

When attempting to load Minolta (mrw) and Sony (arw) raw image files into
GIMP, UFRaw is not properly processing them.  The following webpage has
images which demonstrate the problem:

http://smallthoughts.com/photos/misc/GIMP/index.html

The raw files are being imported with distorted color and contrast.
However, as the additional images show, other programs such as Darktable
and Shotwell are importing and displaying these files properly.

Has anyone else been experiencing similar problems, and is there any known
solution?

Regards.

This is kind of a shot in the dark.  I don't know anything about shotwell, 
and not much about darktable.  But I know darktable automatically applies
an exposure correction curve to the raw file when it imports it, and ufraw
does not (unless you set one as the default).  You might look at the 
exposure correction curve darktable applies and see what it looks like when
you apply a similar curve in ufraw.  There may be other automagic things
darktable does in regards to color; not sure.
