Speaking as someone who has been involved with a large show here in the States for the past 17 years, I can tell you that it is a very time consuming process for our staff to photograph the exhibits. In the past, it normally takes two people working almost the entire two days of the show to bring all 800 + / - figures to the photography booth, photograph them, and return them to the display. Then there is the additional time to upload them to our website. We have tried to several different techniques, to include photographing at night after the show closes, but the amount of time involved still remains the obstacle. It is a difficult proposition for a staff that has a limited amount of people to help during the show. As an example, our staff is all volunteer and is drawn from our local club which means that on any given year, we simply not have the people to run the show and take photographs.
