Just to clarify, I was not referring to covering the DSLR body in foil (although it may prevent aliens taking control of my camera
), I am suggesting to cover the camera body with a copper/alu sheet that's been cut and formed around the camera body.
I have sourced a piece of copper (0.3mm thick) and I am in the process of making a template using thick paper before transferring it to copper.
Will upload photos later.
