This is a double exposure done in my camera which then produced a combined image. I used 2 flash units, a main in front and a fill on the left side. No exposure adjustments were made between shots but I did change focus on 2nd one to the background.
To make the image work I removed the head for the 2nd exposure. Each exposure was a stop under exposed so when combined the proper exposure was given. Processing on color version done in Nik Color Efex and B/W version processed in Nik Silver Efex.
1/125 sec, F/11, at ISO 100. Canon 135mm, F/2.0 prime lens.
