... but then you have to remember the convention properly, and apply it properly, and remember that you did in fact apply it. As I have failed routinely to remember to turn the dark side of the slide outward after an exposure, and/or failed to recall with certainty that I did or didn't turn it out, I rely on the written record that I keep for every shot. Akin to the methods Vaughn (post #66) and Doremus (post #33) use. Each of my holders is numbered on both sides, and that number is recorded in a shooting log every time a negative is exposed. Beforehand, when the holders are loaded, their number and film type are also recorded on a separate page in my shooting log. The record of exposed/unexposed holders is always in my hand or pocket, and because I've taken the time to write loading and exposure information down I am 'cued' to recall/consult it. It's a method that fits my high memory buffer dump rate.
That is exactly what most people did in the old days. You always kept a shot record- either by permanently marking the holders with painted on numbers or by giving them temporary numbers written on tape.
The labs used to give you rolls of stickers that you would paste on the box. These were pre printed with check boxes labeled E6/C41/B&W and then there was a push/pull section. You would then write in the notes section the holder/shot numbers from the log and label the top/bottom sheet and you would request they write those numbers on the sleeves after processing. You could also write next to the sheet numbers push/pull instructions- how these guys kept track of everything always intrigued me- now I wish I asked to hang out and watch them load the machines back then.
This allowed you to identify problem holders immediately (i.e light leaks, focus issues from flatness problems,etc) and/or problems with the camera/lens once you got the film back.
Faulty holders could be a real issue if proper records weren’t kept. Ask me how I know....the shot log really helps you narrow it down if one of your holders turns on you.
Linhof had a good idea with the printed in numbers- but only going up to 12 was pretty limiting in an environment such as a catalog house or guys that did stuff such as supermarket circulars. I worked on some jobs where we were using 50-100 holders a day and reloading 2-3 times.
There were some high paid fashion guys back then that used 3-4 assistants on a shoot and could easily shoot hundreds of sheets of 8x10 a day- which seems almost impossible to believe at today’s film/lab costs.
I was also taught (not everyone did this though) to write down all the pertinent info on the back of the final approved Polaroid proof shot. This way in addition to the shot log you always had a backup record. This is moot these days though....
Another technique that has probably been lost to time (and only really needed when lots of money was riding on the job) was to shoot more sheets than was needed and you would only send half the film to the lab. You would be surprised how many times pro labs would screw up.
It was really a different world back then- and the 50’s to the 80’s was even more different. Hearing the stories of the old timers still working in the 90’s who shot extensively in the pre polaroid proofing days- they used to have an assistant process 8x10 film in paper developer and fix it for 30 seconds and sandwich the wet neg between 2 sheets of glass to show the art director the layout of the shot....
I was glad to have seen the end of that era- it was amazing to see how advanced techniques got right before digital took over. Guys were doing some pretty incredible stuff the old fashion way that took hours or days with multiple exposures or manual retouching that can now be done in minutes.
But it was sad to see the support industries get decimated overnight when digital started coming on. My friend’s uncle was a professional color printer- he used to work with 20 other people printing all night for decades. In 1998 they laid off everyone but him- because he was the only one who knew how to use a computer. Labs were closing left and right- there had to be at least 100 pro labs in Manhattan in 1995- now I think there is maybe 2? Standard E6 service was 3 hours in those days!
