Photogrammetry of assets with cavities

Hello sketchfab peers,

I would like to ask for recommendations regarding how to take photos when scanning hollow objects such as bricks, vases, cups and other containers.

I am using cross polarization to minimize specular reflections. My challenge is to make the lighting inside the cavity or cavities as smooth, even and consistent enough to generate a flaw free and realistic looking cavity in the model.

Thank you kindly
