From the Desktop or Batch, you can use the LUT Editor to apply tone mapping to a high dynamic range image.
Tone-mapping is the process of converting scene-linear media to video media. The PhotoMap tool is inspired by photographic-style tone reproduction. When all controls are set to 0, PhotoMap applies the default tone-mapping curve. By adjusting the controls you can customize the curve to meet the needs of a specific image.
- Access the LUT Editor. See Accessing the LUT Editor.
- From the Conversion LUT Type box, select PhotoMap.
The PhotoMap controls appear. Unless a preset has been selected, all values are set to 0 by default.
- Invert button
Enable to apply the inverse of the tone-mapping parameters function to convert video media to scene-linear media.
- Exposure fields
Displays the value that lightens or darkens the image by scaling the scene-linear values. An Exposure of +1 brightens by one f-stop, an Exposure of -1 darkens by one f-stop.
- Highlight Detail fields
Adjust the contrast in the very light part of the highlight region. Useful for controlling highlight clipping.
- Highlight Contrast fields
Adjust the overall contrast in the bright region of the tone curve.
- Contrast fields
Adjust the overall contrast of the image.
- Shadow Contrast fields
Adjust the contrast in the dark region of the tone curve. Useful for compensating for stray light during capture.
- Shadow Detail fields
Adjust contrast in the very dark part of the shadow region. Useful for controlling the image tone that maps to zero code value.
- Encoding box
Select the type of gamma encoding to apply to the tone-mapped image. Choose the value that corresponds to the response of the display device that will be used to view the video media.
