Last night i took the artwork from my wall and did my first infrared RTI. I would say it is even more exiting than normal RTI as you will see things you are not able to see with naked eye. Artwork I was taking photos of was not maybe the best to show the potential of IR RTI but I hope to try it it again with bigger light-source (I used converted Maglite Mini) and more challenging art-piece.
Click on image to switch in between normal photo and IR RTI with specular enhancement filter. To get the full experience have a look on the original image and the RTI-file (size 144MB). If you do not have RTI-viewer go to Cultural Heritage Imaging website.
