LightZone

michael hughes-10
I just downloaded and installed LightZone on Kubuntu and wondered if anyone else has tried it. I think its very similar to Adobes Lightroom and has lots of features which I find useful In particular the IPTC handling which is streets ahead of digikam.

If you have concrete suggestions for improvements to digikam,
please use the bug-tracker, see
http://www.digikam.org/?q=contrib
under "Reporting bugs and wishes".

Yours sincerely,

I've installed LightZone 3.4
I'm trying desparately to find out about the IPTC features of lightZone but I can't find anything except the very basic stuff like rating, copyright, creator. Can you help me?

I also am starting to give it a try.  I haven't had a lot of time to work with
it, but I think Digikam is far superior for image organization.  In
LightZone's favor is the ability to apply a transformation to a selected
area.  I think that it will be good to use as an external editor, just as
gimp is.  I look forward to hearing about your experiences with LZ.

Hi Gilles,

My comment was by no means a diminishing of Digikam.  I find the digikam tools
work wonderfully for the majority of my photos. I especially like the B&W
effects, for which gimp provides no equal.  Most of my images are nails, and
digikam is a great hammer.  Sometimes though, I have a screwy image, so I
need a screwdriver :-).  In these cases gimp or krita fit the bill.  Digikam
lets me use the tool that works best, to its credit.  

I used to use KPhotoAlbum, but switched to Digikam because it works so much
better for me.  I'm still not done retagging my tens of thousands of images,
but I feel that it is worth it because of the utility of digikam.  So please
don't take my comments negatively, I have the utmost respect for the work
that you and everyone else has done!  Please keep up the good work!

Paul

Hi Paul,
if you're tagging your whole collection you might be interested in reading this:
http://wiki.kde.org/tiki-index.php?page=DigikamDAM

It will be in the documentation very soon.

Gerhard

Gerhard, this is an excellent article! Thank you for this compilation.

One question regarding dng: As far as I know there is no linux software to
create dng's out of raw files, is this correct?

As I have already exchanged my camery and have a pile of raw files from my old
camera, I can do nothing but rely on dcraw's strategy to digest new formats
without dropping old ones - or convert all my files to tiff in order to play
safe. But then I have to create sidecar files for all the metadata...

Re: LightZone

michael hughes-10
I believe LightZone can read DNGs. I wouldnt use LightZone to categorise images any more than I would Lightroom. At the moment I use Imatch under windows. I have an archivr approaching 250,000 images. Anyone got any ideas how I could archive them under Linux?

michael

You are right, there's no DNG software (AFAIK) on Linux yet, unless you want to try this:
http://mat.users.geeky.net/serendipity/index.php?/archives/244-A-dcraw-patch-to-enable-DNG-output-finally!.html

It is of course one of our near future goals to support DNG. It needs tiff writing support be exiv2 and libtiff to start with.
I took DNG up in my article because, whilst it is focussed on digiKam, it take a bit of a general stance on DAM, and DNG seems to be the way to go for RAW. Right noe the best digiKam way to go about RAW is to keep RAW files and to convert into PNG, although there is no full metadata PNG support either.

Gerhard, this is an excellent article! Thank you for this compilation.

One question regarding dng: As far as I know there is no linux software to
create dng's out of raw files, is this correct?

yes and yes...

This is the fault to Adobe :

- DNG sdk is published using a restricted licence, non-opensource compatible. Look here :

http://www.adobe.com/support/downloads/dng/dng_sdk.html

- Linux is not supported in this SDK. Of course to have take a look in source code, this can be fixed without too many problem.

- Abode policy is really strange. Why XMP sdk is published with BSD license and support Linux as well, and not DNG sdk (:=(((

- Only DNG specification are published over the world.

In the pass, i have work on a patch for libkdcraw to convert RAW to DNG... in linear mode. This is bad way. There is 2 DNG storing image data :

1/ RAW linear uncompressed (obsolete)
2/ JPEG LossLess with 16 bits color depth support (hightly recommended in DNG spec)

The first one can be done easily under digiKam, but size file are very huge (~2 or ~3x original RAW file size). This is a non-sense to use it...

The second one is the right way. File size are divided by 2. Problem : algorithm used by Adobe is strongly (c) and certainly covered by patents (i'm not sure about this point)

If you take a look over algorithm, it's an extended version of the old libjpeg for Linux ! Thanks to adobe to use opensource code and to make non-opensource implementations...

Another point is about OpenRaw stuff : It's a web site dedicated to promote DNG format as well... But DNG sdk is not open source compliant... This is why i will never support OpenRaw...

http://www.openraw.org/

It's certainly time to start a petition against Adobe SDK licencing...

Best

Gilles Caulier

http://mat.users.geeky.net/serendipity/index.php?/archives/244-A-dcraw-patch-to-enable-DNG-output-finally!.html

This is RAW linear uncompressed image data storage... Wrong way...

It is of course one of our near future goals to support DNG. It needs tiff writing support be exiv2


Exiv2 author said to me than next main release of Exiv2 will support it
 

and libtiff to start with.

DNG file are tiff/ep file extension. You can writte DNG file using libtiff, in therory, but like there is no JPEG lossless with 16 bits color depth support in libtiff (see my previous message), libtiff cannot help us...
 

I took DNG up in my article because, whilst it is focussed on digiKam, it take a bit of a general stance on DAM, and DNG seems to be the way to go for RAW. Right noe the best digiKam way to go about RAW is to keep RAW files and to convert into PNG, although there is no full metadata PNG support either.

Full metatada support is implemented in digiKam, but wrtting on the fly using Exiv2 is not yet done.

If you open an RAW or JPEG image in digiKam image editor and you cnvert it to PNG, all metadata will be preserved (the image is written from scratch). And when i said all metadata, i want mean Exif/makernote/GPS/IPTC/XMP !

I have an uncomplete patch against Exiv2 on my computer to support PNG writting mode on the fly... I just need to find more free time to complete it.

Isn't there also the additional aspect, that the original RAW
data directly correspond to the sensor data,
which usually are separated into R G B data, in a Bayer array.
Thus some people argue, that it is better to keep the original
RAW, because better Bayer interpolators might be created in the
future. DNG would already contain an interpolated image, right?

Actually, I am not sure how relevant this is in practical
terms, but together with noise reduction etc. it might be important
in some cases?

yes, if you read DNG spec, you will see than RAW original image data can be hosted at the same time than JPEG lossless 16 bits image. But in this case, the DNG file size become huge...

So, DNG is not easy to use in RAW workflow...

You can  try Adobe RAW DNG converter under linux using wine. it's not too bad :

http://www.adobe.com/support/downloads/product.jsp?product=106&platform=windows

here, i have hosted few sample to take a look : http://digikam3rdparty.free.fr/TEST_IMAGES/DNG (RAW converter)/

I think you have a point there, but: RAW file formats will be obsolete after some time, as I said in my DAM article, in the long run you will not be able to read RAW of the past. Therefore it is better to convert to DNG.

Hmm, I don't fully buy this one ;-): As long as dcraw compiles
and does not introduce back-wards incompatible changes
(i.e. omitting decoders), all should be fine
(Well, of course the safest might be to store a copy of dcraw together
with the raw images. Then only(?) bit-rot or changing compilers
could do harm...)

Best, Arnd

DNG (was Re: LightZone)

Fabien-5
In reply to this post by Gilles Caulier-4
Hi,

I don't know if it could be useful, but I started recently to use chdk
firmware in my ixus 800is :
http://chdk.wikia.com/wiki/Main_Page
http://chdk.wikia.com/wiki/SD700_CHDK_Porting

This allows me to add features to the camera as bracketing (really great
to make HDR photos) and raw.
The raw file can be processed by dcraw (and so digikam and other tools
based on dcraw). But, there's also a converter to DNG format :
http://dng4ps2.chat.ru/index_en.html

It creates files that are slightly smaller than the original raw file,
but not sure if it's so different than the dcraw output...

Fabien,

This program use DNG SDK inside !!!! And it's published under GPL !!!

Really nice. I don't know that i can use no-gpl code into a GPL project... especially if Non-GPL code is published with restricted closures.

From the tarball, we have this file :

[gilles@localhost ~]$ cat dng_lossless_jpeg.h
/*****************************************************************************/
// Copyright 2006 Adobe Systems Incorporated
// All Rights Reserved.
//
// NOTICE:  Adobe permits you to use, modify, and distribute this file in

/* $DateTime: 2006/04/05 18:24:55 $ */
/* $Change: 215171 $ */
/* $Author: tknoll $ */

/**
 * \file Functions for encoding and decoding lossless JPEG format.
 */

The Adobe License have been removed in this tarball. Great for an opensource program !

Or perhaps i missing something about licensing relevant of my primal English (:=)))...

Comments are welcome...

Gilles

I'm anxious to read this, and apparently everyone else is also.  I get this
when I try to view the link:

Unable to connect to the database !
 User wikikde_kdewiki already has more than 'max_user_connections' active
connections

:-(
