Modify the Display Settings

Modify the appearance of a rendering during post-processing.

On the ribbon, click the Rendering tab.
Click the Darkroom icon.
In the Image Browser, click the rendering you'd like to edit, and then click the Edit Image icon.
Modify the Display Settings.

Note: To discard all modifications to the display settings for the current image, click Default.
To apply the modified settings, click Save Changes.

Display Settings

You can modify the exposure, tone mapping, and filtering; add effects; view the render channels; reduce noise; and perform a photometric analysis.

ISO: Controls the sensitivity of the image sensor. Higher values result in brighter images.
Tip: A value of 100 is mostly used for exterior shots under a clear sky and sun light. Higher values, usually between 400 and 1600, are used mostly for interior shots.

Exposure Value (EV): Controls the camera's shutter speed. Lower values result in brighter images.
Tip: For an overly bright scene, use a positive value. For an overly dark scene, use a negative value.

Gamma: Default value: 2.2. Lower values will make the image darker while higher values will give a washed-out look.; Gamma correction is important if you want to display an image accurately on a computer monitor. It controls the overall brightness, as well as the ratios of red to green to blue, of an image. Without proper gamma correction, the image can look bleached out or too dark.

The Filmic option only works if you turned on Filmic in the Camera/Rendering settings.

Shadows: Higher values will make shadows darker.
Highlights: Higher values will make highlights stronger.

It controls the overall brightness, as well as the ratios of red to green to blue, of an image. Without proper gamma correction, the image can look bleached out or too dark.
Exposure: Higher values will increase the overall brightness.
Radius: Adjust this value to remove tonemapping artifacts.

Exposure: Higher values will increase the overall brightness.

CRF: Camera Response Function simulates specific camera models using real data files from the manufacturer.; Select a camera from the drop-down list.

Sharpness: The default value (50%) is a balance between blurring and sharpening. Only applicable when Supersampling is set to Normal or High.; A value near 0% will produce a more blurred image, while a value near 100% produces a more sharpened image.
Burn: The burn value minimizes the burnt areas of an image. Lower values will reduce burnt areas.; You can use Burn to compress a high dynamic range into a low dynamic range image, displayable on screens and other limited range devices.; Setting Burn to 100% has the same effect as disabling it.
Chroma: Chroma enhances the color of the image, acting like a saturation control.; Higher values result in more saturated images. Setting Chrome to 0% has the same effect as disabling it.
Contrast: Higher values will give higher contrast.
White Balance: Can be used to balance an image using color temperature. A value of 6500K is usually used to balance light coming from the sun.

Glare: Introduces a bloom effect in the final image.; Choose from Radial, 5 Blades, 6 Blades, 8 Blades, or 12 Blades.; Weight: Controls the intensity of the glare effect.; Radius: Define the length of the blades.
Vignetting: It mimics the phenomenon where light comes through the lenses near the edges. Higher values will make the edges of the image look darker.

Channel: Shows a list of all the active render channels with the ability to switch between them.
The default channel, which is rendered every time, is the Color Channel.; Min/Max Z (m): Min Z and Max Z values refer to the Depth Channel. Min Z sets the minimum distance from the camera.
Note: Although you can define Min/Max Z strictly during post-processing, we suggest using good initial values to avoid aliasing issues when no supersampling is present.

This option is only available if you turned on Denoiser Filter in the Camera/Rendering settings.

Denoise

Reduces the amount of noise in the final rendered image.

None (default)
NVIDIA Optix: To use Optix, you need a NVIDIA GPU with a compute capability of 3.0 or higher and a driver version of 396.65 or higher.

NLM: This denoiser filter is only available if you selected the Presto/IR engine.

Strength: Controls how much the denoising filter will affect the final image.
Details: Controls the similarity in the level of detail between the final rendering and the original image. Higher values correspond to more similar levels of detail.

To see the changes in Strength and Details, click the Refresh button (in Edit Image mode, the rendering doesn't update automatically).

Analysis: Turns the image into a false color rendering, so you can perform a photometric analysis.; Min/Max Il-Lum: Min Il-Lum and Max Il-Lum represent the range of the luminance (cd/m²). By changing these values, the false color image is adjusted accordingly.; You can select multiple regions of interest where you can analyze the extreme points and distribution of values. You can generate a full report that can be viewed in any web browser.
