UV Images Exhibit in Weinheim

So this is about my upcoming next UV picture exhibit which will be opening September 20st, 2008 in Weinheim, Germany in cooperation with very creative and esthetic Christian Mayer Floristik. That same weekend "Weinheimer Hebst" ("Autumn in Weinheim") will take place, with all shops open during the whole weekend. (No big deal you think? Not in Germany I tell you...)

So have a look, these images will be on display there for a few weeks [click on image gets you a larger image]:



















and this is how it looks now there:

Stay tuned, more will follow on that fascinating subject...

UV and Forensic Skin Photography I

This will be the start of some entries about forensic photography. Using different wavelengths, filters, lenses and special lights, I would like to show, what may be documented on human skin using these techniques.

Lets start documenting some bruise and its development over time. Reflected ultraviolet photography is said to be able to detect these bruises even if they have disappeared in the visual. So let's see....

Here now the first image set, top row is bruise after + 4 days, second after + 8 days. Color is useless in this content I thought, so it will be "just" black and white images. I will elaborate on the different filters and wavelengths used later.

And here how that looks like 44 days (1.5 months) later, it gets clearly visible that the normal, visible light photography hardly picks up anything of that healed bruise, whereas the special setup used (image on the right) still clearly shows that old, healed bruise!




And this is how "invisible" older and already healed scratches may be made visible:




...more will follow on that.


So I hope you like these as much as I do....

Stay tuned, more will follow on that fascinating subject...

UV Fluorescent Minerals

Today now very bright images which fluorescent minerals can provide. A very good friend of mine was so kind to open up his mineral collection "vault" for me and I was able to take some shots of his shotwave and longwave fluorecent mineral collections. Since he has the needed ultraviolet lamps already installed in his cabinets, a "normal" camera and lens was sufficient, tripod mounted because of the somewhat longer exposure times.

Here now the images, click on them to get larger ones:









and this now an also fluorescent shrimp:

Stay tuned, more will follow on that fascinating subject...
