Wellcome fellow rockhunters!

Just a few info about me and my minerals. I live in Prague, Czech Republic. I started collecting in 1983. Mineralogy is "just" my hobby, not a profession - I am a neurologist.

My mineral collection is composed nowadays only from self collected specimens. The only exceptions are gifts from my family or friends and a couple of specimens bought in the end of 80's (again gifts from my parents).

I do go out for field collecting nearly every week, the great amount of my "mineral" time is taken by macro and microphotography of my specimens.

The last of my mineral hobbies is photography of specimens from Czech Republic in museums (where You can see the glorious specimens from the past - e.g. Prague, Wien..)...and of course I upload photos to and edit text in Czech locality pages on MinDat.

I take my photos with Canon EOS 6D with:
- Sigma 24mm f/1.8 EX DG Aspherical Macro (FOV above 50mm)
- CANON EF 100/2.8 MACRO USM (FOV above 18mm)
- CANON MP-E 65mm f/2.8 1-5x (FOV 3-18mm)
- stereomicroscope MEIJI EMZ-13TR (10-70x) (FOV under 5mm)
- Zeiss Luminar 16mm with bellows (FOV under 3mm)

I do use photo stacking with Helicon Focus for MAC.

Examples of some of my favorite specimens collected in 2009 and 2010:

Thanks for Your visit and enjoy my photos!

A ridiculously colorful specimen, consisting of brilliant, transparent crystals of bright red Carminite, associated with yellow Beudantite, iridescent blue botryoidal Goethite, and a single thin white Cerussite crystal. This specimen was challenging to photograph, primarily for two reasons. First, there is a wide range between the brightest and darkest elements of the image, and second, the colors of this piece are both highly contrasting and highly saturated. To offset the reflectivity of the specimen, this photograph was taken under reduced light, and that light was further controlled with two layers of diffusing media. Even with this technique, the difference in image brightness between the brighter elements, such as the Cerussite crystal, and the darker elements of the image, posed a challenge to both the camera and the image processing software. The field of view is 5 mm. Ex: Hans Börner collection. Robert Meyer specimen and photograph. Photo of the Day - 6th Aug 2009
