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...
