A while back, I bought a used Olympus E-PM2 off eBay and had it converted to full-spectrum usage (i.e., I had the anti-IR filter removed from its sensor). Add an IR filter to its lens, and you can get some interesting effects with the setup — so I took it up to the mountains to the Breckenridge International Snow Sculpture Championships:
After split-toned processing, this is an infrared image of the “Dia de Muertos” snow sculpture, created by a team from Wisconsin. This sculpture won the “Artists’ Choice” award this year, well-deserved if you ask me. The level of detail that the sculptors could achieve with packed snow is impressive.
