darktable – photography workflow application

February 28th, 2011 No comments

i just stumbled over this nice and free application.

http://darktable.sourceforge.net/about.shtml

a virtual lighttable and darkroom for photographers: it manages your digital negatives in a database and lets you view them through a zoomable lighttable. it also enables you to develop raw images and enhance them.

this project tries to fill the gap between the many excellent existing free raw converters and image management tools (such as e.g. ufraw, rawstudio, f-spot, digikam, shotwell). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. the main focus is on user interaction, both in terms of a smooth interface design as well as processing speed. high quality output is also one of our goals.

all editing is fully non-destructive and only operates on cached image buffers for display. the full image is only converted during export. raw image loading is done using libraw and rawspeed, high-dynamic range, and standard image formats such as jpeg are also supported. the core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).

it is amazingly fast compared to other equivalent (but costly) tools like adobe lightroom, apple aperture or bibble labs.

it also has plugins that enhance the funcionality a lot. in my opinion it’s functionally equal to the highcost payware.

try it out!

a few days ago i found this very nice raw-picture editor and converter. its pretty close to what you can do with the commercial variants like adobe lightroom, apple aperture or bibblepro.
the nice thing with this piece of software is that it also supports linux systems. which from the commercial ones only bibblepro does. thumbs up! dope stuff.
you can find out more here: http://www.rawtherapee.com/?mitem=2
AND DONT FORGET to donate the author a bit.

compile dcraw raw image converter under debian lenny to support canon eos 7d .cr2-files

April 20th, 2010 No comments

after a long search i finally found a method to compile dcraw under debian so that it can handle the raw files of my canon eos 7d.

just do the following:
download the c-source from http://www.cybercom.net/~dcoffin/dcraw/dcraw.c
open a terminal and navigate to the folder you downloaded the c-source.
then install two libraries needed for compiling dcraw

apt-get install libjpeg62-dev

apt-get install liblcms1-dev

after that compile dcraw with the following command

gcc -O3 -o dcraw dcraw.c -lm -ljpeg -llcms

then copy the compiled version of the program (dcraw not dcraw.c) to your /usr/bin

now you are set.
navigate to a folder with raw pics and just type

dcraw *

now it will batch convert all the containing raw files

i found this info here: http://www.camerahacker.com/Forums/DisplayComments.php?file=Digital%20Camera/RAW_converter_for_linux

Inkscape – OpenSource Vektorgrafikeditor

August 13th, 2006 No comments

Inkscape ist ein Open-Source-Vektorgrafikeditor, dessen Fähigkeiten mit denen von Illustrator, Freehand, CorelDraw oder Xara X vergleichbar sind. Inkscape verwendet das vom W3C standardisierte SVG-Dateiformat (Scalable Vector Graphics). Unter anderem ermöglicht Inkscape die Arbeit mit verschiedensten Formen, Pfaden, Texten, Markierungen, Klonen, Transparenzeffekten (alpha), Transformationen, Farbverläufen, Mustern und Gruppen. Außerdem unterstützt Inkscape auch Creative-Commons-Metadaten, Knotenbearbeitung, Ebenen, komplexe Pfadoperationen, Bitmaptracing, pfadgebundene Texte, objektumfließenden Text, direkte XML-Bearbeitung und vieles mehr. Es können Formate wie PostScript, EPS, JPEG, PNG und TIFF importiert werden. Exportiert werden PNG sowie verschiedene vektorbasierte Formate.

Inkscape soll ein mächtiges und komfortables Zeichenprogramm werden, das die Standards XML, SVG und CSS zu 100% einhält. Durch den offenen, community-orientierten Entwicklungsprozess hat Inkscape eine wachsende, lebendige Benutzer- und Entwicklergemeinschaft bekommen. Damit das auch so bleibt, achten wir darauf, dass Inkscape einfach zu bedienen und zu erweitern ist.

Inkscape. Draw Freely
