Optimal way to shoot with a RealSense camera
Dear Intel RealSense team,
We are software developers from Korea and currently, we are using RealSense Camera in our project.
To use the RealSense camera, I took pictures using photography lighting
When we were comparing the results between before and after lighting, it is been found out that the user's face is clearly visible when lighting is used, but it seems that the depth value is not clearly found.
Therefore, I am curious if using lighting would have any effect on the Lidar sensor of the RealSense camera.
If there is an optimal way to shoot with a RealSense camera, I would like to know how to do it too.

Hi Dev Luenah May I first confirm which RealSense camera model you are using, please. The question is tagged as D400 Series but lidar is mentioned. The 400 Series cameras are Stereo Depth technology, whilst the L515 model is Lidar. Thanks!

Thank you very much for confirming your camera model as a D435i stereo depth camera.
Intel have a RealSense camera tuning guide at the link below that is a very good reference for advice on achieving improvement.

RealSense 400 Series cameras can make use of any visible light in a scene to analyze objects and surfaces in a scene for depth detail. They can also obtain depth detail by projecting an infrared dot pattern onto surfaces in the scene. The dot pattern is helpful for obtaining depth if a surface with low texture detail is being observed.
The dots would be cast onto the face and be readable as texture that is translatable into depth. RealSense cameras are Class 1 laser devices that are safe for the face and eyes.
Which type of lights are you using in your photography setup, please? If they are fluorescent lights (like ceiling strip lights) then they could cause disruption to the camera image because they flicker at frequencies that are difficult to see with the human eye. Use of LED photography lights would be preferable if you are not using them already.
