Took this image of chocolate today and couldn´t believe my eyes! The out-of-focus highlights were turned into stars!
But why is that?
I exposed the image at Iso 50, 1/500th and f4. The camera used was a Sinar Hy6 with a Carl Zeiss 120/f4 PQS Makro-Planar which uses a leaf-shutter. Apparently the shutterspeed was too fast and the shutter already closed while the flash was burning down. The result is that the leaves of the shutter are seen in the highlights. On top of this, the shutterblades act like aperture leaves and closing the effective aperture creating larger depth of field. A teacher in photo-school once mentioned this effect but i thought that it is only theoretical.
