I'd like to tell you  what happened when I was practising and preparing poses.
Several photos were  taken and reviewed over several days.
Suddenly I noticed  'an orb' to my right. Strange to have missed it before as it is so  prominant. Six of the many photos taken that day, were found to have  orbs of some description, but many did not. The first one that was  noticed was the one that was sent to the RAM listing.
 I had heard of  these orbs but had no experience or knowledge. Naturally
an investigation was  started and I now believe, (there is, at present, nothing conclusive,) that these  are balls of energy of some sort, which absorb flashlight and expel it  at a reduced wavelength. The digital camera, being an electronic  recording device, can pick up 'near infra-red' light.
Experiments have  shown these orbs to be consiousnesses of some sort; could be beings,  thought forms, nature spirits etc. I have had fun directing my camera up  into the dark night sky. It's very interesting what comes out,  particularly little faces.
My fellow artist and  model in our group was surprised to find several orbs in pics he took  of three models over two sessions.
It's all good fun !
