This was taken about 1/2 hour before i slept, without any light source except for the LCD screen from my laptop which was on the table that time. Taken using Nikon FM2 loaded with Ilford iso 400, i purposely used RM 15 shutter release cable at about 21600 seconds. Guess what? That is equally to 6 hours. How did i calculate 6 hours?
I personally don't know the answer, perhaps, this is what i call lame experiment.
p/s: yes, those are my complete dragonball comic books!
