It can also be interesting for diagnostic purposes to see how large or small difference there is in color rendering between the illuminants, but as said for general use this setting should be untouched. About Shows information about the original author of RawTherapee and the current version, details of the build, names of developers and other contributors and the RawTherapee 4. VNG-4 used to be in version 2. This mode may also be understood as 'Relative mode'. Note that on some distributions the RawTherapee cache folder name might have a version number appended, e. As this information is saved within the image file it cannot get lost.

RawTherapee Review – A Powerful Open Source Alternative to Adobe's Lightroom
It uses wavelets and a Fourier transform to work its magic. The drawback of this mode is that e. Image before, image after correction and the flat field file used.
This might lead rawtheraapee some banding effects, especially visible in blue sky. To create the best possible output, feed RawTherapee with the best possible input - so expose well in the first place!
This is because you need to tell RawTherapee where your raw photos are stored. Raatherapee same tone curve is applied separately to each R, G and B channel. Please mention that RT only knows about one monitor.

Works well for correcting vignetting and lens cast. Having multiple photos opened at the same time requires more RAM. Flat field correction removes both color and luminance non uniformities and results in a perfectly uniform image. We strive to ensure backward compatibility, but this is not always possible.

Rawthegapee RawTherapee was based on integer math it was wise to not use larger working space than absolutely needed to get the best precision in the calculations. Whether this is desirable is debatable. The lightness is kept separate from the color, so that you can adjust one without RawTherapee 4.
Examples of photos that have been over-recovered can be easily found on the internet. Each values of the same component are then mixed together, which will produce the resulting color with a smaller color shift.
Notice that a new horizontal line appears when you start dragging a color point, and see how its color changes. Most third-party DCP profiles with embedded tone-curve will work well without the tone-curve applied, however in some cases it may affect the intended color rswtherapee negatively and then it may be better to enable it.

Double-check these things before sharing your profiles. The histogram of an incorrectly processed photo. Under the widget, RT shows how many shots are found and how many groups of shots are found and averaged into a template.
If at 0 only the corners will be feathered and the rest of the image will not be affected by the filter. You can see this by dragging the red line on the left a bit to the left.
It has the same filename as the output file, but it has the. A well known example of such non uniformity is vignetting — a peripheral darkening of the image, more pronounced in the corner areas. Lightness This slider applies a fixed tone curve to lift rawtgerapee lower the tonalities of the photo, resulting in a more or less bright image.
Notice that those lines are colored; from left to right: It will open in a new tab, the Editor tab. Luminosity preview is helpful to instantly view the image in black rawtherzpee white without altering development parameters, to see which channel might be clipping or for aesthetic reasons.
Histogram on the bottom after image indicates that corrected image does not have any variation in the tones, exactly what one would expect from a uniform flat field. The dotted diagonal line marks rawtherzpee linear or unaltered state of the photo.
This feature is generally only to be used for diagnostic or scientific purposes. The horizontal axis corresponds to luminosity: Chromaticity The Lab Chromaticity slider increases or decreases the chromaticity of the image, by applying a contrast curve to the rawthera;ee and b-channels of Lab space.
Dark Frame Specify the directory on your hard disk for searching for the dark frame shots for long exposure noise subtraction.
