For maximum visual parity between the viewport and the render, it is strongly recommended to disable some of Unreal's post processing and lighting components.

The exposure and color corrections do not work as a global PostProcess volume and are individual per camera. To see the changes you make to the VRayPhysicalCamera's settings in the viewport you have to look through the camera itself. |

Aperture F-number vs Shutter Speed vs ISO
Cheat Sheet
The main options that control the brightness of a V-Ray Physical camera are Aperture F-number, Shutter Speed and ISO. They affect each other and you need to balance them according to your scene. Keep in mind that these settings do not correspond to those of a real-life camera. They apply only to the V-Ray Physical camera.
