The following settings can be adjusted:
- Filter Colour—Choose the colour/tint of your lens filter.
- Optical Density—Adjust the density (or strength) of the lens filter: this controls how much of the tint is blended into the image.
- Preserve Luminosity—When checked, prevents the change in colour from affecting the luminance channel of the image. If unchecked, increasing the optical density will typically reduce the luminosity of the image.
