Exposure | Adjusts the exposure of a photo or video layer, making it appear as if more or less light had been captured by the camera. Increasing or decreasing the exposure primarily affects the brighter parts of the layer. Range: -2 to 2; Default: 0 |
|
Gamma | Applies a gamma correction to the layer based on a power function. Range: 0.01 to 9.99; Default: 1 |
|
Offset | Makes all pixels in the layer brighter or darker by adding the offset value to the RGB values of the pixels. Range: -0.9 to 0.9; Default: 0 |
Usage
Add this effect to a photo or video layer, then adjust the properties as desired. Typically, this effects properties are adjusted in the following order:
- Offset: Paying attention to the darker parts of the layer, adjust Offset until the desired darkness is achieved (if any parts should be pure black, match them in this step).
- Exposure: Paying attention to the lighter parts of the layer, adjust Exposure until the desired lightness is achieved (if any parts should be pure white, match them in this step).
- Gamma: Paying attention to the mid-tones and overall result, adjust Gamma until the desired result is achieved.
Images and Video
/Exposure/Gamma is best used with images and video.
Use Cases
- Correct video or photo that was under- or over-exposed by adjusting Exposure.
- Brighten the darker parts of a photo or video without over-exposing the lighter parts by adjusting Gamma.
- Intentionally clip out parts of a luminance mask by using Offset to shift the luminance values towards the extremes.
- Calibrate the black and white points in a photo or video.
- Make interesting fade-to-black effects by keyframe animating Gamma towards zero or Exposure towards negative values as you ease into a fade to black (the final fade to black must be done with another mechanism such as layer opacity). Animate in the other direction for fade-to-white.
