Can infra-red camera make a picture of object inside hot shell?

Question

We place an object (say, steel cube) inside hot sperical shell,
which has no sources of light, other than blackbody radiation,
and wait until thermal equiliblium settles inside the shell.

After that we try to make a picture of the object through
small hole in the shell using infra-red camera.

Answer 1

Sure, you can take a picture.

What will you see?

Blackbody radiation from the object.

Blackbody radiation from the shell reflecting off the object (since the object itself isn't a perfect blackbody).

I don't know how good the image will be. The reflections should let you see something of the object's shape if you can make them out over the object's own thermal radiation.

Answer 2

It it's a true blackbody environment, no, features cannot be distinguished from the background, as everything will be emitting exactly the same radiation spectrum curve uniformly in all directions. A true "whiteout", in the case of 5500K temperature.
