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. The artwork that 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 a bigger light-source (I used converted Maglite Mini) and more challenging art-piece.
