Mineral PhotographyPhotomicrography

Although not (yet?) mineral related, this link Microsculpture takes you to a website with absolutely amazing microphotographs of insects. Each photograph is composed of up to 8000 stacked shots. It takes the photographer some 3 weeks to finalise a single image.



I would love to see similar pictures of microminerals. Clara Mine, Bellerberg, Água de Pau volcano, Poudrette Quarry, Aris Quarries or many of the slag localities would be wonderful “candidates”.

Cheers,

Hi Wolfgang,


very impressive. Technically the photographers of insect are far ahead the mineral photographers.


But the insects shown are often big , more than 1 cm. The objects from the location you mentioned ore often smaller than 1 mm.

Technically you can combine a square of 10 mm from 100 pictures each of 1 mm. Each stacked lets say 500 times. This gives a picture with a resolution in the 1 µm range. Made from 50 000 individual pictures. By the way this is about 25 % of the lifetime of a camera shutter.


Unfortunately this can not made with a 1 mm object, because the wave length of visible light does not allow a resolution of 0,1 µm.

The mineral photographers struggle still with the 1 µm resolution.

As Volker has pointed out, the trick is not to image something in the centimeter range, but to clearly image a mineral that is sub millimeter size.
