Very nice. You're certainly getting good at what you do when you mind

K01 with reverse mounted SMC K 24 f3.5, 70 stacked images. I could not
position a flash well to shoot into the crystal (it is very 3
dimensional) so I used ambient light which resulted in a shutter speed
of 0.4 seconds per shot. I would prefer to use the flash to counter any
vibration related blur, but the long exposures came out OK.
Comments welcome.
