On holidays in Sri Lanka I saw these nuns approach. I raced back to get camera & IR film from my hotel and was lucky that they were still there when I got back.
Thank you everyone for your kind words - it is good feeling when you think you have taken a good shot and you just have to wait until you get home to develope the the film and find out. The joys of photography.
Lyonheart - the glow is an attribute of infrared film if exposed correctly.
