Getting all that I could out of this before all of the seeds fall off. This setup has been out on the bench for a week or better. Finally shot it today. 5D MK II, Canon 100mm F2.8 Macro. F6.3 @ 1/8 second. 79 images stacked in Zerene Stacker for depth of field. Final B/W done in Silver Efex Pro. How is that for more info than you ever wanted to know? (click for the larger version)
