Question about RAW processing: ufraw files?

Hi,

I am considering to use digikam and have a technical question about RAW
file processing:


Until now I used to process my RAW images with ufraw, a nice graphical
frontend for dcraw.

ufraw has a useful feature, the so called ufraw batch files, which are
small XML files containing the
parameters for the RAW->pic conversion. So there was actually no need to
keep a pic twice on the
disk, it is enough to have the RAW and the small ufraw with the
description, allowing to
generate a processed picture at any time without human interaction with
ufraw-batch (which takes
both files and generedes the processed output).


Does digikam support a similar feature (or is it able to deal with ufraw
files) or would I have to keep
all my raw pics twice, both as raw and jpeg (or tiff)?


regards
Hadmut

There is no deal with ufraw sidecar files

digiKam has already Batch RAw converter as kipi-plugin.

in digiKam 0.11, a new Batch Queue Manager is implemented. You can
batch Raw file, resize it, make color adjustements, convert to
PNG/JPEG/TIFF, all in the same time.

Well, this might be a nice tool, but not what is called "batch mode".
It's still something you call on the graphical user interface with the
mouse. Remember, this is not about Windows, this is Linux. So something
is needed that can be used from within a script file (because that's
what's actually called a batch mode).

If I understand those examples correctly, the digikam 'batch mode' would
apply the same settings to all pictures, not individual settings for
each one. And it requires to store each picture twice, both as raw and
e.g. jpeg.


Well, would be really nice to improve that.

Nevertheless, thanks for the good work.

Hadmut

well, you want batch tool in command line : use imagemagick + bash... etc...

We talking about graphical interface for linux... do you know ? do you
know a mouse to move on the screen ?

It's time to learn modern computer science, especially for begineers,
who don't know scripting. This is the caseof Pro photographers, who
don't care about programming. These guys don't have more time for that
!

This is my goal : make GUI for non programmers... It's really more
interresting than to write something witch run in backgroung in a
console...

Also, are you take a look to Bibble pro software and the really nice
batch raw converter ?

yes. If you want to apply different settings, make more than one batch
tools pool. Start Batch Queue Manager, and go to take a coffee... All
will be done few minutes later (:=)))

well, let's go. i waiting your patches...

Gilles, it's OK to do GUIs for non programmers, but I'm sure you
understand that imagemagick + bash actually don't do a lot of things
needed by photographers...
Since a lot of these things are already features of digikam (I mean, the
code to do them is still there), it would be really nice to have some
way to do these things ALSO on the command line, or through some script
like other editors out there do, just like gimp does.
For example, I'm thinking about Lightzone, the -old- linux version (I
don't know anything about the new one) let you create editing templates
that you can re-use to edit a batch of similar images. That templates
were just text files, and you could edit them as you wish, if you wish
and obviously if you can.

I think that scripting and command line operation could be that
"something" more that could do the difference between digiKam and picasa
or other alternatives... that linux console thing, with scripting, could
add a lot of features to our favourite photo managing software, don't
you think?

Maybe we should leave a door open to it, even if it isn't in the to do
list at the moment...

I hope I didn't write stupid things.

gerlos

On one hand your wishes are sensible - for long time this was also my wish.
But on the other hand new batch tool in 0.11 (svn trunk) looks very promising.
Of course at the moment there is no complete functionality provided by all
kipi/digikam plugins + ui is a bit rough (I plan to write more about this soon
on devel list) but future looks really good.

There is other thing I still think would be nice addition to digiKam: easier
cooperation from inside digiKam with other tools - also some console tools
like ImageMagick.

Last but not least: apart from Gilles attitude to this solution I understand
that Qt/KDE framework isn't really designed for headless (read: no-GUI)
operation like you want to do. To do this for existing program would mean some
awful hacks, big, big, really big code refactoring, etc. Without those - even
when communicating by dbus would require start-up of GUI which defeats whole
concept of command line tools.

Note that more extensive dbus interface - especially for metadata plugins -
would make digiKam easier to use in some heavy duty environments with existing
data structures (second thing I want to elaborate on devel list).

Wow... I can't wait for it! :-)

Maybe something like service menus in knqueror/dolphin? It would be really
great!
I could put together a really complex command script to do something really
strange, and trigger it on my photos just choosing it from some menu in
digikam... I'd love a feature like this!

I understand these difficulties, I didn't though it was so an hard work. So the
batch queue manager is the fastest and more efficient (and last but not least,
easy for the user) way to go, isn't it?

Mmm... I didn't understand this last point... :-(

Me too. digiKam will never be able to make everything which all users would
want to do. Simple extending by service menus could really help people with
weird requirements (which sometimes even should not find its way into
mainstream digiKam!)

Batch queue manager which is in the working + service menu like in Konqueror
which is only wish in B.K.O :(

I have data some database. I'd like to be able to transfer those data to
digiKam and use it to fill metadata. At the moment I have two ways: get data
from original database and put it into photos directly using tools like exiv2
or exiftool or put data into digiKam database and later use tool for syncing
db with photos. Both those methods are very error prone on various levels.
dbus interface could take care eg. about correctness of data.

Well, of course there is third way - manually type all this data into metadata
kipiplugin...

Forgot one feature promised in batch queue manager: in options is Custom tool
position which according to Gilles should allow for assigning any external
program - in effect fulfilling this wish :D
