I use Digikam to organize my image files, trim, edit, run batch processes, include watermarks and just generally keep my image libraries organized.
A few of my favorite features:
16 Bit Per Channel Editing
Just like the big boys. 16 bit per channel color depth. You can spend hundreds of dollars for a program that does the same thing, or get Digikam for the cost of a Ubuntu CD (which is free) and a Digikam download (also free).
This is nearly a must have for photographers working with RAW files.
The Light Table
One of the features I like most about Digikam is being able to pull images from different portfolios on to the light table for side-by-side work.
Digikam also lets me scan large image collections and add specific images to queues. Queues are how Digikam opens up all the program functions to you for batch conversions.
Sort of old fashioned in these days of iPhones and Google Calendar, but it’s a neat feature all the same. There’s sort of a retro appeal to an old fashioned print calendar and what better than one featuring your own pictures.
Create an MPEG slide show from your photos and burn it on to a CD or DVD.
Key Word Tagging
Tagging and ratings that help me search for images across directories. I can classify them by event, and Digikam can automatically place all the images I took on a certain day on a list.
Rotate Image Based on EXIF Information
Certain cameras record the orientation of the camera when they take a pictures. Digikam can read this information and automatically orient your pictures (if you enable this feature).
So a quality photo editing application and a world class operating system, all for free. Worth a try, don’t you think?
