2009-10-07 - GPS tagging

Some weeks ago I got a TomTom One IQ Routes. As TomTom is Linux based, it's also possible to add new applications. On opentom.org I've found TTTracklog for tracklogging. Also very useful - TTTracklog-ext, to start and stop logging. Now let's tag some files. There are many programs for this purpose, but after making some inquires Prune was the one which looks most promising. Most of the programmes use Exiftool for tagging and also just support JPEGs. As I work only with RAW files, I wanted to tag these files. Exiftool rewrites the complete exif header, but for some cameras Canon has reserved some space for GPS data. So I started writing a small Exiftool clone which just supports writing GPS data. Cr2GPSTag was born. I have done some tests, but please make a backup of your RAW files if you run Cr2GPSTag the first time. Special thanks at this place to Sebastian Hofer for providing me a original Canon tagged CR2 file.

2008-11-13 - Mac users, is it running?

I thought it's time to have a look into the logs files after I got some positive responses. I found many request by Safari browses, but Mac OS is not on the list of official supported platforms. You may ask why it isn't on the list, rawdev is based on Qt and Mac OS is used by many photographs? The answer is very simple: I have no machine to compile and test the application. But I would like to add Mac OS the list of supported platforms. If anybody tried to get it running or got it running, please send me an e-mail!

2008-11-04 - how rawdev was born

Before rawdev there was only one open source raw develop engine - dcraw. Dave Coffin, the author of dcraw, has done a good job in reverse engineering many different formats, but in my opinion the program is to monolithic. Many other projects use dcraw, but they have to fork it to use it as a library. Also the color management could be better. As already discussed on the digiKam blog the color matrices where taken from Adobes DNG Converter but not the complete processing model. First I tried to solve all drawbacks in the dcraw code itself, but after a short time I realised it's better to start from scratch. Rawdev was born.

2008-10-29 - rawdev can now rotate and crop images

A new version of rawdev is online! New in this version is the rotate and crop filter. As usual the filter can be used from command line and gui.
