Hi,
 
can anyone here use successfully the digikam flickr export with wide gamut
pictures ? I mean with a sRGB source picture exists no export problems .
 
Greetings Steffen

Hi Gilles
 

hmm i dont think so, i mean the "wash out colors" like this mailing-thread:
 
http://digikam.1695700.n4.nabble.com/trouble-with-image-degradation-using-DK
-with-kipi-plugin-flickr-export-td4440543.html#a4444341
 
 if i edit this photos with the digikam "image editor" to convert the color
space to >>sRGB<<< and after this i take the export, all its fine. my
archive images have mostly a nikon wide gamut space. 
 
all images are resized before to be sent to flickr. 
 
Cheers
 
Steffen

It's sound like a bug in Flickr... Excepted if image are re-sized before to
be sent to web service, file are passed as well to flickr. 

If images are resized, color conversion are done in background by Qt API
through QImage. photo are converted to sRGB normally.

Do you see any difference with or without size transform ?

Hi folks
 
the kipi plugin flickr export has a problem at the color space conversion
from proPhoto Gamut, Wide Gamut ... to sRGB:
 
i use the windows version: 
Version 3.0.0 
Using KDE Development Platform 4.9.5 
 
and i have the same issue at the end of 2012 - 2013 about the color space
conversion at the flickr export.

-with-kipi-plugin-flickr-export-td4440543.html#a4444341
 
 If i make a sRGB colorspace conversion with the image editor, gimp or
photoshopper and export this picture to flickr all is fine. But so i must
create copys of each photo to avoid the loss of the bigger color space of my
archive photos ... and this creates a intricate workflow 
 
Exists actually a patch to solve this? 
 
Cheers 

 
Steffen
