Lead photo in the Melbridge Dock article in the current BRM is this shot by Andy York showing the Y7 shunting behind Dougie and a seagull.
Back in 1997, Tony Wright took a very similar photo.
Andy's pic was taken on a digital camera. He's post-processed it to make sure everything is in focus and then delivered it to the editor via the Internet.
Tony took his on a medium format camera which had an adjustable back to improve the depth of field - the first model railway photographer to use this sort of kit. Photos were taken on transparency, 72 by 60mm. He would take three of each shot - one for the mag, one for his records and the third for the layout owner. Transparencies had to be scanned in for use. All the work had to be done "in camera".
Andy does take more than one shot, or at least his camera does. Most photos are now made up of multiple images taken with different focus points - and staked to produce the infinite depth of field required by today's mags. Fiddling with images to remove dust or unwanted backgrounds is standard practise.
Digital has certainly accelerated the work though. Tony produced 12 images in half a day at my house. Andy shot 34 in about an hour at the show.
I wonder how things will change in the next 19 years?
