i'm not sure this qualifies because technically, there's only one photo... but there was a fair bit of photoshop work...
1 - i created the background in photoshop (black with white cut out for the door)... exported it to my iPad and used it as a backdrop to shoot the penguin...
2 - penguin was standing against the iPad on a reflective surface... so the reflection was properly caught on camera...
3 - processed in LR then ported in to PS to create the moon... and add some light glow... and gradient to dull out some of the reflection...
anyhoo... i'm tagging it for the challenge but will completely understand if it is felt that it does not properly qualify...
so interesting to read how you put this together. A sort of composite. I imagine a whole animated sequence with penguin searching for the source of the light in which he is standing.
