Teeth and UV I

Today about teeth and ultraviolet photography.

I found in some older books some contributions of Prof. Woods and esp. Ch. Lunnon about photograping teeth using ultraviolet light.

So here some results using my calibrated for UV X35 lens, a Baader 2" U-filter and my newly developed High Power UV flash.

The top image clearly shows, repairs, cracks, plaque etc. whereas the second one using a special filtering technique also shows bacteria build up (plaque) as reddish cast and repairs having being done. The small size of the images here do not really show the amount of detail which gets visible using these techniques.

Lens Comparison: UV Nikkor 105mm, COSI 105mm, B&L 9"

Today I got an old lens, which was made many years ago by famous lens maker Bausch & Lomb, Rochester NY. It is a golden color single coated, heavy and well made f4.5 9" lens which attracted me, since it was made to record images emitted by a P-16 phosphor screen. Nothing special actually, but P-16 radiates at about max. 380nm, so now you know what attracted me most...

I ran a quick test using my "standard test subject", a roof of the neighbours house against the Coastal Optics Micro Apo 105mm and the Nikon UV Nikkor 105mm. The B&L lens results are shown on the right side of the comparison images. The B&L images have been scaled down to match the shorter focal length of the other two lenses. These are 100% center crops. The Baader U-filter (310 - 390nm) was used for the reflected UV shots. [click on image gets you a larger image]

Here the results in visible light for the UV Nikkor (left):

So now it is up to you to understand my surprise, how amazingly sharp this B&L lens is....

Allium (Onion) in UV

So this is about onions in UV light. These have very cute ball-shaped flowers and I wondered how these would look like in UV "light". The petals seem to have quite some strong UV reflectance to attract pollinators.

So have a look, left is the visual image, middle the reflected UV image and right the image with UV remapped into the visual as blue [click on image gets you a larger image]:




And this one in a bit higher resolution:




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

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:

[exhibit ended Nov 7th, 2008]

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

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. 
[click on image to get a larger one]




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:



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

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

Literature on UV (and IR) Photography

Now this one won't contain pictures and new findings, but a list of literature which deals with UV photography. I have collected that over the years and I am very greatful for the work of Dres. Williams who have provided also quite a few useful resources which I will happily included also.

So here it is:

So I guess the oldest (1903/1910) source should be by the inventor of the famous "Woods glass" Prof. Robert Williams Wood, who made the first UV transmitting glass filter and the reason why these filters sometimes are still called "Woods Glass".
