Ice and IR?

[matti]

The sky is black. What would a big lump of ice be if recorded with an IR-film with an IR-filter? Not the right season for me to check it out myself. But I got curious.
Would it reflect the IR from the sun and be white or?

It would probably be white. Snow and ice is fun to shoot with color IR.

It's white - or rather, it reflects IR just as well as all other colours.

At least a glacier is white, except where it's grey or blue to the eye.

I'll see if I can find that negative.
