This is actually only one image. The idea came up in the bathroom, seeing the condensed mirror.
The orange glow is the reflection of the shower curtain.
The "skull"? I don't know. Didn't see it when I took the picture. It came up developing in Lightroom.
Postprocessing: only some (a bit more extreme than usual) shadows and highlights, and crop to square.
This image is made for the Totally Informal Thursday Transglobal Challenge on March 6th 2008 -"Something Sinister".
