Ted by fire in infra red
Just been playing with a cheap second hand Nikon D50 with Infra Red filter (cuts out all but IR light).
IR photography is virtually impossible with my newer cameras.
Use a CD/DVD like a diffraction grating to project the spectrum of sunlight onto a table. (Not a prism, because its glass may block part of the spectrum. Do this outdoors). Lay matchsticks as markers at the reddest & bluest colours you can see. Take a photo. Colours will go outside the matchsticks. Inspect photo to see how much IR and UV the camera can see :-)

Aaaaah...I wish I had a fireplace, and could stretch, in front of it, like Ted. I'm afraid some of my old bones would crack....
The word ver. is glizeso!!
I would think that infrared was Ted's natural milieu ...
Neat experiment:

Finally a worthy subject for a portrait. Be careful near the fire as Tuxedo cats are fond of Roast accountant.
Aw, that's so atmospheric.
It's nie to stretch out in front of it but the cats won't let us CLaude!
It reminds him fondly of his real home at Satan's right hand Bryan!
Haha that's true Beak!
Thanks James
