Image processing tools


1) Color Cast

This function removes a color cast from the image - or adds it.


2) Exposure

The Exposure slider adjusts the brightness of the image. It increases the brightness of the individual color components. Unless the "Brilliance" slider is moved to the left, the colors are shifted towards white, similar to overexposure in the camera.


3) Brightness

With this slider the brightness of an image can be changed without adjusting the color contrast.


4) Contrast

Increasing the contrast increases the difference between light and dark. The colors will not be displayed more intensely.

If the contrast is reduced, the image becomes paler overall and the color contrast is also reduced. However, if the "Brilliance" slider is also moved to the left, then an increase in contrast will also affect the colors.


5) Shadow

This allows the darkest areas of an image to be darkened further or their brightness to be increased.


6) Highlights

Darkens or lightens the brightest areas of the image.


7) Saturation

Use this to adjust the saturation of the colors.

When you click the selection box, the image is displayed in black and white mode. You can then move the Saturation slider to make (to the left) the reds or (to the right) the greens brighter.


8) Dynamic

This slider works differently to the left and to the right:

(a) Shifted to the left, the image is darkened and the colors are greatly enhanced at the same time. This can make landscapes or objects illuminated by colored light very striking. You can soften or enhance the darkening effect with the Exposure and Contrast slider.


9) Colorize

You can add a color overlay with the 3 sliders to adjust the colorization.

You can enter a color as a HEX value by double clicking on the rectangle in the upper right corner.

Use the first two sliders to select the color, the third slider to select the intensity and the application mode. If the third slider is positioned more to the left, the color will be subtracted in the image, if it is positioned to the right, the color will be added transparently. (Multiplication).

The color overlay is activated with the selection box.


10) Detail

Here you can set the radius of the blur, if no layer is selected. With the slider you can adjust the mix between blur and contrast enhancement.

The selection box can be used to enable and disable this feature altogether. If it is disabled, image changes can be calculated faster.

Please note: The Detail feature requires a second pass to develop the image. The selected radius has a global effect on the possible gains of the local contrast and the possible overlay of blurred image data.


11) Curves tool

You can adjust the contrast of the image with 2 curves. The curves can be added to all layers individually.

Here you can adjust the contrast of the image individually by raising or lowering certain RGB (RGB curve) or brightness ranges (Luminance curve).
