Scanning an onion without a scanner.
I pealed and sliced a red onion, layed it on a plexiglas, attached a flash with snoot over it, so that the snoot hit the glas and was lying on my back photographing upwards. Then it just took a little post to clean up the whites - this shot made me cry.
Making of here.
Light: SB24 with snoot, 20cm above onion, 24mm, 1/8 power, skyport
