Nattress Levels and Curves feature highlights include:

° Film-log space — editors have all the benefits of fine control over the tones in an image and film-like contrast handling;

° The on-screen curve display helps editors fine-tune curve and/or level adjustments. The curve display can easily be turned off when footage adjustment is completed.

° A library of presets lets you apply popular level corrections, or create and save custom presets to use again and again.

° The black and white level inputs and outputs can be set, plus gamma curve control allows for fast and functional levels control.

° Curves RGB offers individual control over the RGB channels. The control set is duplicated for each channel allowing for precise control over image tones and colors.

° Curves Luma — users can work on the luma component of an image only. When a user adjusts luma curves, it only alters how bright or dark the tones of the image appear; color and saturation are not affected.

° Curves work in RGB space equally across all three channels. As contrast increases, so does the perception of image saturation.
