Thanks to my mate Chef and his lovely wife Eiko for being there and making it such a lovely day.
Two shots, each made with the 50mm f/1.2 AI lens on my D700 set at about f/4 and with some discarded clear plastic I found in Chef’s living-room wrapped around the front.
Shot with a fluorescent white-balance and the camera set to the Fuji Velvia picture-control I have.
Opened both in Photoshop, merged them [as I meant to make a multiple-exposure at the time but was laughing too much to remember to set up the camera properly].
Cropped to a square from the original aspect-ratio.
