Raw Therapee – which stands for The Experimental Raw Photo Editor – is a free editor for RAW images, the unprocessed image format used by reflex cameras.
A RAW image is not ready to be used as an image; it’s more like a digital negative you can process to obtain the final picture. And Raw Therapee makes the whole process very easy and enjoyable.
Raw Therapee supports lots of different RAW formats and features a ton of adjustments to process the images and obtain the final result you’re looking for. You’ll be able to tweak brightness, colors, shadows, contrast, color balance… and also transform the picture by cropping or rotating the image, among other possibilities. A feature we especially liked was the ability to create snapshots. This lets you save all the changes you've done so far in case you need to revert to them at any point.
Some of the adjustments have automated settings, but not all of them. Also, Raw Therapee doesn’t have any documentation, so it’s more a question of trying out all the possibilities to see which one looks best.
With Raw Therapee you can process your RAW images in a friendly, easy-to-use interface.
