Mirada supports color correction of the image in the uploaded media file. Commands from the drop-down list on the toolbar at the bottom of the viewer or shortcuts can be used to control the color correction.

  • On/Off (G shortcut) allows you to enable/disable the color correction mode.

  • Settings… (Alt+G shortcut) allows you to enable the color correction mode and display its property window.

Mirada supports color correction of images with a large color depth (more than 8 bits per color channel).

Model Basic

You can set the following parameters in the property window in the interactive mode:

  • Gamma (the default value is 1.00). This parameter mostly affects the middle tones of the image — when you increase the value, the image becomes lighter, and vice versa.

  • Exposure (the default value is 1.00). This parameter mostly affects the light tones of the image — when you increase the value, the image becomes lighter, and vice versa.

  • Exposure (the default value is 0.00). This parameter mostly affects the dark tones of the image — when you increase the value, the image becomes lighter, and vice versa.

Model Display Range

The brightness level is displayed.
