Dear colleague, we try to apply IR photography only in some selected autopsy cases. We have the best experience with the visualization of tattoos (e.g., in putrefaction, mummification, soot imbibition of the skin, etc.). We use Fujifilm IS Pro, CoastalOpt® UV-VIS-IR Lens 60 mm and various IR band pass filters. Sometimes, we apply IR photography for visualization  of subcutaneous  bruises and gunshot residues (e.g., latent shooting, gunpowder tattooing). We, also, tried to apply IR imaging for highlighting of electric marks, but without surprising results. And your experience?

Dear Dr. Hejna

I had an old Nikon d50 modified internally with a 900nm filter,  I think that are very good results. (send photos)

Now I am just wondering what happen with soot and tattoo in gunshot wounds using this technique.

Dear Jorge,

We have Fujifilm IS Pro - a version of Nikon D300 (suitable for both IR and UV photography) and CoastalOpt® UV-VIS-IR 60mm Apo Macro (manual focusing).

Link for lens: http://www.jenoptik-inc.com/coastalopt-standard-lenses/uv-vis-nir-60mm-slr-lens-mainmenu-155/80-uv-vis-ir-60-mm-apo-macro.html

We apply IR photo:

1. gunshot wounds.

2. tattoo identification.

3. detection of soot and gunpowder particles on dark textiles.

4. detection of blood on dark textiles.

5. bites.

6. skin lesions on the pigmented skin.

We have tried to employ in electrocution cases but without benefits.

Take care.

Petr

We may share our experience!

Hi Petr 

Nice to read you again.

Amazing equipment !!! as you can suppose it  is inaccessible  for me,  I´m working, in this field, with my own camera, lenses and speed lights, so imagine my face when I visit the link  that you have sent.

Congratulation, and please, share some pictures !!!
