As the spring back simply slips into the 'channel' created by the lugs in the camera back it can of course be used like an adaptor ... but the original ground glass on my '7x5' is dim and has a chunk missing ... so building in a method of taking a modern ground glass that's much brighter was topmost in my list of priorities. The 13x18 ground glass 'well' in the window frame back won't securely hold a modern glass without a lot of modification, so I decided the 'window frame would be fitted with a ground glass made by me to size and put back in place, allowing me to either use old style wooden plate holders with the original film holder mounting ... or swung out of the way to allow the modern style springback.I've made adapters to take modern 5x4 DDS, the adapter just slips in place like an original book form plate holdr so you use the original groun glass screen. I did the same to use a Graflex RH10 6x7 roll film holder on a quarter plate camera.
A little while ago I let my eight year old grandson (a totally digital generation kid) 'assist' me through a 5x4 shoot ... the look of wonder as he saw the negatives come out of the wash water was a picture in it's own right. He said a very telling thing: 'it's as lovely as waiting for Christmas'.I think you’r right about the patience. Our pictures can even be distributed worldwide, seconds after they are taken. We’ve been spoiled.
Not only that, but taking a likeness would have seemed unbelievably fast compared with the alternatives, painting or drawing. I recall seeing, somewhere, astonishment that the camera could capture any number of people at the same time.
Lacquering is my catchall word here ... on all the newly made woodwork so far I have used my hard wearing finish of choice: Birchwood and Casey Tru-Oil (intended for gunstocks). Technically it's neither a lacquer or a French polish ... but is old fashioned varnish that's closer to the latter as it's applied with a cloth and built up in layers to the desired shine. To be honest functionality is more of a concern than 'originality' here as this camera will be hopefully used a good deal.Lacquered ? It should be French polished.
Since I retired from professional photography my living has been made in the musical instrument sector ... hence the Tru-OilTru-Oil is excellent stuff. I have used it on the last six musical instruments that I have built - five guitars and a harp. Like Marley, I apply it with a cloth. When the finish is built up enough, I leave it to harden for a week then rub it down with a paste made from Tripoli Powder mixed with baby oil. This gives a silky smooth gloss finish which looks wonderful.
