several Sigma DP2 raw files are publicly available here - http://www.rytterfalk.com/2009/05/13/dp2-raw-pack-ii

and there is also a mixed set of DP1, DP2 and SD14 raw files (Sigma's X3F format) - http://www.rytterfalk.com/raw/mixed_raw_pack.zip

that should be good enough for a start ?

thank you in advance !

embedded JPG is displayed in browser even now - but if you can also display as many (at least basic) exif tags (ISO, f-stop, etc) - that will be very good, even if you will not be able display the raw data itself !

any chance to get that done at all ?

Roland Karlsson updated his source code ("c/c++") to read the updated .X3F format = http://proxel.se/x3f.html = http://github.com/rolkar/x3f

that might be helpful to add the functionality to read exif tags...

Look what I can see (I am not a software developer though) :

if I will take his utility "x3f_extract" and run it like:

x3f_extract -jpg [.X3F raw file]

then I will get an embedded .JPG thumbnail extracted from .X3F and that .JPG ___has correct EXIF tags___ that we are looking for... I am right now looking at both files in XnView and see that myself.

so either

1) his code (where the source is available) can in fact read EXIF tags from .X3F

__OR__

2) the embedded JPG thumbnail itself is in fact .JPG file __with necessary EXIF data included__ ...

in this last case XnView already has access to embedded JPG thumbnail and you can just get the EXIF tags from there instead of .X3F - even easier for you to implement...

Am I right ? that will be awesome ! please.
