I am intrigued by what I have read so far about RawTherapee. Right now, my workflow is similar to yours, except that when I leave Nebulosity, I bring my image into GIMP for final processing, which, of course, involves the loss of data due to GIMP's 8-bit color depth. I did not know about the existence of RawTherapee until I read your post and the previous posts in this thread. I'd be interested to see if anyone else is using RT for processing. Processing parameters can also be named and saved, then batch applied to any future photographs as a starting point with one click. Raw Therapy Linux offers very sophisticated and powerful 16-bit loss-less processing, and is very stable. Results (more being added all the time) can be seen at. Then open for post-processing in Raw Therapy, which has far more processing tools and options. I use Nebulosity to acquire deep sky images, stack, and adjust as much as it can, then export, saving as a lossless 16-bit TIFF file. I've never used Photoshop, so I cannot compare the two. I have been using Raw Therapy Linux distribution for processing astrophotos for some time. At some point the question has to be asked regarding processing of how far it departs from original frame information, becoming essentially a reconstituted photo based on some programmer's "artist's conceptualization." Then open for post-processing in Raw Therapy, which has far more processing tools and options. RawTherapee offers distinct advantages over other raw converters I have tested, producing images with smaller stars, color to the cores of stars, even saturated stars, finer detail in nebulae and galaxies, and lower apparent noise.

Process one photo from the set than save options and apply them to all images from the set in batch queue.Īnd, of course, it is freeware, multilingual with different OS support (Windows, Ubuntu, Gentoo, Mac OS). The main feature of the program - possibility to save and reapply all of used tools in batch processing (presets). Highlights and shadows recovery tools (!) Unsharp mask, RL deconvolution, contrast HSV (Hue-Saturation-Value) curves and color managemen
In a program arsenal - a full toolset for batch and single postprocessing: However, as it turnd out, it perfectly suitable for postprocessing of astrophotographies (taken with DSLRs). Initially the program is intended to edit and convert RAW pictures from digital cameras. All of these features and more make RawTherapee a great tool for working with photos in RAW format.Let me introduce my new find - RawTherapee, the freeware program for postprocessing of images with 16-bit color.
With RawTherapee, you can lighten an image that's too dark by adjusting curves, smooth the skin in portraits, get rid of imperfections, recover color with the white balance, and give colors a purer tonality. Once there, you see all your pictures, and even use RawTherapee to rate them as you see fit. You just have to open the file explorer and find the folder you need.
It also lets you see a history of all the changes, along with the picture's metadata. This tool has all the basic photo editing features, like the ability to adjust brightness, contrast, levels, colors, sharpness, image noise, crop, resize, etc. Although the effects take some time to be applied, the results are pretty impressive. The features in RawTherapee, and even its interface, are similar to those of Adobe Lightroom. This tool is compatible with most formats for DSLR cameras (such as NEF, DNG, among others), and also supports the traditional formats like JPG and TIFF. RawTherapee is a photo editor that's specially designed to work with RAW files. Even though pictures in RAW format are known for having a higher quality than any other format, it can be difficult to find an image editor that supports it.
