Adobe Lightroom is a popular photo editing application, available on smartphones, tablets and desktop.
The most common task is correcting for white balance.
#TODO What is the tone curve?
Burning and Dodging: make bright brighter and dark darker
Brightness controls the overall look from bright to dark
Contrast (the ratio between highlights and shadows)
Highlights controls the brightness/contrast of the brightest parts of the image
Shadows controls the brightness/contrast of the darkest parts of the image #TODO histogram analysis of highlights vs whites, shadows vs blacks
Whites shifts the colors by moving the white point
Blacks shifts the colors by moving the black point
Both adjustments are mainly used for correcting for while balance if the shooting conditions affect the subject.
In the Mix mode, you can edit individual colors in the photo.
In the Gradient tab it’s possible to perform similar hue adjustments but focusing on shadows, middle tones or highlights at a time.
Lens corrections, sometimes useful for wide lens and fixing fish eye effects.
Other image distortion tools.
