This can be used to change the brightness of an image. Different than the Exposure option found in the Color management panel, this exposure option works on the data while the Color management exposure is on the view transform.
Due to limited resolution of images and computer screens, pixel filters are needed to avoid Aliasing. This is achieved by slightly blurring the image to soften edges.
Pixel Filtering algorithm to use.
Default filter with a better balance between smoothness and detail preservation.
Lower values give more crisp renders, higher values are softer and reduce aliasing.
Render the background transparent, for compositing the image over another background after rendering.
- Transparent Glass
Render transmissive surfaces as transparent, for compositing glass over another background.
- Transparent Roughness
For transparent glass, keep surfaces with roughness above the threshold opaque.
