For those who might be considering doing this, don’t unless you’re ok with destroying the camera.

How does it destroy the camera?

Most DSLRs are designed to withstand down to 0C. Most freezers are around -20C. You risk damage to the battery, condensation on interior components, contraction and mechanical damage of components with tight tolerances, etc.
