Does anyone have any recommendations for free software that provides the key features of Lightroom in one package? The main things I am looking for are:
- RAW photo editing
- Library management
- Multiple catalogs
- Rich keyword/tag support
RawTherapee is a decent open source alternative to Lightroom.
You could try Darktable. It's available for Linux (and OS X) and resembles Lightroom.
There are two approaches here:
I suggest you to try both ways before coming into a final decision.
We, at Daminion Software, adhere the second approach - and I suggest you to check out our Daminion.
It's free, supports multi-user environment, can automatically sync your tags with the Camera RAW metadata (NEF, CR2, MWG, etc...), support for hierarchical keywords and categories.
I suggest you take a look at Raw Therapee as a decent free RAW editor.
BTW why you did not mention your platform (PC, Mac, Linux) and your preferable Camera RAW format. It's not free but many Nikon photographers use CaptureNX to edit RAW files.
i think that picasa (from google) can do this, but it's not as powerful.
It is free as in beer, though.
Light Zone is free and much like Lightroom. Give it a try. It's free
