## **Image Sampler**

---

**Overall image sampling** - Raytrace renders, like V-Ray, shoot rays out from the camera to sample what is found in the scene to help determine what color each pixel is in a rendered image. The settings used to adjust how V-Ray does this, and the relationship between pixels in the render can be found on the [Image Sampler](https://docs-chaos.atlassian.net/wiki/spaces/VC4D/pages/116855825) (Anti-Aliasing) page.

**Region rendering** - When V-Ray uses a bucket image sampler, the rendered image is broken up into small pieces, also known as buckets, to help calculate and complete the image faster. The settings for adjusting these buckets can be found within the [Render Region Division](https://docs-chaos.atlassian.net/wiki/spaces/VC4D/pages/116855825/Image+Sampler#Render Region Division) section.


## **Color Mapping**

---

A camera in the real world uses exposure controls to determine how it handles the brightest and darkest parts of a captured image. Similarly, V-Ray uses **Color Mapping** to help translate the information collected by the sample rays into usable pixels we see within our rendered image. *For more details on how to control the way V-Ray maps these values, please see the **[Color Mapping page](https://docs-chaos.atlassian.net/wiki/spaces/VC4D/pages/116853304)*.


## **Color Management**

---

The Color Management rollout allows you to switch between the** sRGB** and **ACEScg** color spaces. *For further details, see the **[ Color Management](https://docs-chaos.atlassian.net/wiki/spaces/VC4D/pages/116856523)** page*.
