Raw Therapee v4.0 Binary Downloads for Microsoft Windows

Before I switched to Lightroom, I was one of the core developers of Raw Therapee, and while the old 3.0 and 2.4 are frozen, RT itself is under constant development. Here you'll find current builds of version v4.0 espc. for Windows 64bit. I am happily using Raw Therapee for production. It's a typical open source, never 100% bug free but happy to fix critical bugs if they come along. Please report bugs here on Google Code issues list.

What's new in Raw Therapee 4 (previously named 3.1, changes since 3.0)

Floating point engine - RT is probably the only real time RAW converter doing image processing with high precision 32bit floating point (in contrast to 16bit integer like 3.0 and other)
More eye candy - Nicer icons and looks
Much enhanced file browser - Colored tagging, searching, filtering...
New image tools - Like tone mapping, color vibrance, black level compensation, output gamma, microcontrast, post demosaic artifact/noise reduction...
Better highlight recovery - More (Blend) and redesigned (Color propagation) options, and more headroom with floating point
New camera profile engine - faster and natively built for Adobe DCP files, support for CaptureOnes and Nikons profiles also
Lens corretion profiles - Support for most Adobe LCP files
Flexible UI - you can hide panes, disable and move sections to adapt it to your need and screen size
Improved edit window - grayscaled and precise clipping indicators, more color probings, RAW histogram with linear/log mode, F5 opens processed file in default editor, curves auto-open...
Better color management - New color management system and more precise handling, monitor profile auto-detection
More keyboard shortcuts - To work faster
More command line options - Allow you to automize RT using scripts or calling from other programs
Sound - Informs you when e.g. the batch queue is done
XMP copy-unchanged - Keep all the metadata in your pretagged RAWs (e.g. DNGs)
Stability improvements - Bugfixes and structural enhancements that did not make it in 3.0, espc. for Windows

Warning

Don't even try RT 32bit below 2GB of memory. To let it run stable during coversions (which use the most RAM):

Set Windows 32bit in 3GB mode. Look here for how to set it, and here is the full explanation. If XP has problems booting, also add /userva=2900 after /3GB.
Close all other programs
Set RT in Multiple Tab Mode
STOP the RT Batch queue, no Auto-Start
Edit all your pictures, and send then to the batch queue (do NOT save them directly!)
After you're done: close the preview image tab (because open images soak RAM)
Change to a directory that has none or only few images in RT (images in file browser soak RAM)
Then start the batch queue. Do not open any images while processing
Biggest RAM hogs are Contrast-by-Detail, Denoise, Shadow/Highlight in high quality. So do not enable them if your image doesn't need them.
