![]() ![]() For example image comparison is still missing. Version 2.4 improves the GUI and the file browser that has still some long road to run before competing with products like Lightroom or Adobe Bridge, but already snapshots and batch processing are there. ![]() Also a basic lens distorsion is added (that Lightroom does not have to date.). Typical corrections like cropping, white balance, free angle rotation, chromatic aberrations and vignetting are included. ![]() Take for example the common highlights on a human face because of the reflection of sunlight: we much prefer to see the blownout area as pink instead of grey, don't we? Look at an example here: Normal highlight effectĪlso sharpening algorithms seems to be good. ![]() You can download the raw images to prove it yourself and compare the outcomes with your favourite RAW converter (and add your feedback as a comment to this article).Ī second very interesting characteristic of RT is the propagation of color for highlight recovery, a very useful feature in several situation, something we'd like to see in much more expensive RAW converters.īasically, RT can propagate the last correctly displayed color into an area that is blownout instead of the common way to use grey (like Adobe Camera Raw and others do using the principle -where I cannot determine the color, I use the neutral grey-). I personally reproduced the comparison with latest version of RawTherapee (2.4) and of Lightroom (2.4 too) that uses Adobe Camera Raw and RT is significantly better in this job, though at expense of a noiser image. Raw Therapee has compared this on a test image from a Nikon D70 and it achieves the best result with comparison to all other popular RAW converters: DxO holds the second place though the rendition of colors is worse, Adobe Camera Raw is the third one with good colors, others (like Bibble or LightZone) are much worse, producing very visible moiré. The first of Raw Therapee notable characteristic is the ability to extract details avoiding moirè (the false colors generated when a texture is too fine grained for the sensor resolution). The demosaicing algorithm (the process to pass from the RAW image in one-color to a "normal" color image) is selectable between 3 ones, and EAHD gives impressive results. The decoding of RAW data is done through the free and famous DCRaw (link here). The 2.x versions are a big step forward with respect to version 1.x in terms of usability and some features (already included in version 1.x) are particularly interesting, especially how the RAW data are handled, achieving results in some areas better than most of other RAW converters, included the popular Adobe Camera Raw. Raw Therapee ( ) is an open source (donation are appreciated of course) software for RAW development. Up to date builds can be downloaded here: The release build on is a couple of years out of date so it's best to use a dev build.On 21st of July Raw Therapee 2.4 has been released. I don't do any retouching except basic spot removal - just color/exposure kind of stuff. I use RawTherapee and think it's great for my needs. You can look into ratios, then align the picture with you / the stairs with some free software ( for example). Suggest you plan to install a dedicated RAW convertor such as RawTherapee and invest in the (lot of ) time need to familiarize yourself with it. Vintage glass on digital v black and white Both free and open source, more than enough capability for non-pro use. I use digikam to organise my photos and rawtherapee to edit.
