Pentax-k5 RAW photo problem

[Pentti Rautio]

Bought yesterday new Pentax-5. In k5 you can save raw either to PEF or
DNG and in adobe or srgb. Digikam gives an error with PEF and
prosesses DNG with a purple stripe (in top when vertical photo and in
left with a horizontal one). You can crop it and you have an image
which is equal or almost equal size to the camera jpg. After one day
and 50 shots I don't see any problems with colors.

I don't know the difference between PEF and DNG, both are compressed
16 bit to 14 bit, I guess, and are about the same size 23Mb.

Currently I use Ubuntu 10.10 with Digikam 1.8.0. and have used digikam
for about two years. I am very happy with digikam.

Darktable is able to render both RAW forms (PEF and DNG) correctly but
Rawtherapee, DNG-converter and Darkroom cannot.

(Lately I have used Rawtherapee alfa version for difficult RAW:s and
after prosessing do the rest in digikam).

I Have about 80.000 -90.000 photos from  mainly Nikon or Sony, about
one third are RAW. System has internal disk space of 2.5 Tb. Currently
I move the images first to small and handy 500Gb Samsung usb disks and
use them also to move photos to other systems if needed. For backup
there are external bigger usb-disks.

Hope for Pentax-5K file support in the near future.

Thanks for an excellent program.

Pentti

Hi.

Which digiKam version ? which libraw/libkdcraw ? Go to Help components
info for details.

Which digiKam error you see ?

Can you provide a PEF file to test here ?

digiKam Version 1.8.0

PEF  : unpacking of RAW unsuccessful (or something like that in English)
DNG  : can be processed but in the result there is a purple coloured
stripe (approximately 50pixel wide)

This is definitively the problem. libraw is too old. The last stable
version is 0.13. Libraw is include in libkdcraw from KDEGraphics
component.

I'm sure that K5 is supported very well. I have some PEF test files on
my computer

Update libkdcraw to a more recent version, and all will be fine. Of
course digiKam need to be updated too.

Note : as libkdcraw is installed with KDE, updated KDE to KDE 4.5.5
must be the solution

Best

If you download and build with these instructions
http://www.digikam.org/drupal/download/KDE4
You will NOT got the libraw you need for PEF and will build 1.8.0

If you use these instructions
http://www.digikam.org/drupal/download/SvnAlongStable
you will get the correct libraw as well as build 1.9.0
K5 RAW PEF are editing perfectly for me.


I found this to be true several weeks ago.
