I keep getting stunned by the imagination and vision of images that populate this site. And at times I feel like organising an appointment to see the pictures even if it includes a flight to Sydney or Melbourne and a (budget) hotel room for the duration. Air travel is cheap these days and it is commonplace for art lovers to travel to a distant city for a block-buster exhibition or even to look at the works of a master.
But, and it is a big but, I can't be sure the images have material existence. They may be no more than electronic files that look the same on my monitor here in Noosa as they would look on a monitor in Sydney. If I keep asking posters on this site what their images are I may become a nuisance or even come across as impolite. On the other had it may be construed as insensitive to viewer interest if a poster merely puts up an unknown picture on a like it or lump it basis.
What do you say to a policy of requiring a basic caption and description for all posted pictures? We (I?) surely deserve to know if the thing illustrated on the monitor screen is an electronic file, a platinotype photograph, a gelatin-silver, a wet plate, or something else wonderful and strange.
