Correction of highlights and shadows (analogous to the “Shadow/Highlight” tool in Photoshop).
Parameters in the example: width=200; height=200.
Resizing a photo.
A filter that processes a photo with a sepia effect.
Parameters in the example: hue_in_degree=80; fixed_saturation=0.6.
A filter that colors a photo into shades of one specified color.
Parameters in the example: balance=70; shadow_saturation=80.
The filter produces split toning of the image.
Depending on the parameter, makes the original photo “warmer” or “colder”.
Gradient Map maps the equivalent range of grays in an image to the colors of a specific gradient fill.
Parameters in the example: default.
Corrects colors in an image by combining the “Color Temperature” and “Highlight and Shadow Correction” filters.
The filter's operation will be barely noticeable in photographs with initially good color correction.
Parameters in the example: default.
Filter for automatic image enhancement. Includes highlight and shadow correction, color temperature correction, sharpening correction, noise reduction, automatic saturation adjustment and portrait filters.
Parameters in the example: default.
Filter for automatic correction of image color saturation.
The filter's operation will be barely noticeable in photographs with initially good saturation.
Parameters in the example: red=100; orange=-40; yellow=-60; green=-100; aqua=-100; blue=-100; purple=-100; magenta=50.
The filter highlights the components specified in the parameters in the image and makes them more saturated, while the remaining components are converted to black and white colors.
For this filter, you can also set its transparency .
Parameters in the example: default.
Sharpening the image.
Parameters in the example: default.
Gives photos a warmer, sunny tone and adds contrast.

Color tone
hue
4.18879
0
6.283185307
The shade of color (hue) into which the image is converted. The value ranges from 0 to 2*π (default value means purple, 0 means red, 3.14 means turquoise)
color tone in degrees
hue_in_degree
0
359
The same as the previous parameter (hue), but measured in degrees. If this parameter is specified, then the hue parameter will be ignored (or rather, recalculated from hue_in_degree using the formula hue = hue_in_degree * π / 180°)
fixed saturation
fixed_saturation
0
0
1
With the value fixed_saturation=0, the saturation value of the original image is preserved (black and white photographs will remain black and white, color photographs will be colored in the specified shade). For 0 < fixed_saturation ≤ 1, the saturation value of the original image will be multiplied by fixed_saturation, i.e. for small values of fixed_saturation the result is poorly saturated. The higher the fixed_saturation, the more saturated the result. (When set to 1, both color and black and white photos will be colored as much as possible in the specified color)
bleaching
desaturate
False
Whether to desaturate the image before toning. Value true - yes, false - no
balance of lights and shadows
balance
50
0
100
Balance between light and dark tones. Many pixels whose brightness is lower than this value will be considered "dark areas", and pixels whose brightness is higher will be considered "light areas"
color tone of shadows

0
0
360

color tone of lights
highlight_hue
0
0
360
Color (hue) toning of light areas. The value is specified in degrees, which correspond to the value of the color on the color wheel. 0 — red color
shadow saturation
shadow_saturation
0
0
100
Saturation (strength) of toning of dark areas. The lower the value, the closer the color is to shades of gray; the higher the value, the stronger the saturation of the color shade shadow_hue
light saturation
highlight_saturation
0
0
100
Saturation (strength) of toning of light areas. The lower the value, the closer the color is to shades of gray. The higher the value, the stronger the saturation of the highlight_hue color

5
The parameter sets the degree of intensity change for the blue and red components. A value of 1 corresponds to the original image. If the parameter value is less than one, the photo will acquire a cold tint. A value higher than one will give the image a warm tint.
