Does anyone know how much silver it takes to make a roll of black and white film? I think maybe less now than previously, but no idea about what the amount might be.
For Tri-X it's 0.37 grams for a 36 exposure 35mm roll, currently costing $0.35 or about 4% of the retail price of the roll.
You'd have to figure out how strongly the cost of raw silver affects the cost of film (and/or paper). Of course, that's still a different question from how strongly a film manufacturer or reseller thinks they can make you believe how strongly the silver price affects the price of their product.
Their accounts show that for years their single biggest expense year on year is purchasing silver
I also buy silver nitrate in very much smaller quantities (about 25g per year) for my school laboratories. The price has shot up sickening amounts.
What counts in terms of adding to film or paper costs is surely what percentage of total material costs is affected by a silver price rise of X %? So does anyone know, as opposed to inspired guessing, what effect in percentage terms a known rise in the price of silver actually has on film or paper?It is likely that the % cost per roll of silver content has increased, because the price of silver and it's compounds has skyrocketed. But it's still likely not the most expensive component.
inspired guessing
Pretty much the last thing you'll be able to extract from the grip of a dying manager's fingers will be the cost breakdown of their product. So inspired guessing is probably as far as we'll ever get.
Release of such a cost breakdown would give competitors a huge market advantage.
The cost of silver for a roll of film is still unlikely to came close to the cost of buying the backing paper for a roll of 120, much less the costs of confectioning the roll, and getting it through the distribution chain.

I think with the chemical knowledge of many of the members here, they could come up with an experiment to strip popular films of their silver, separate it, and weigh it. It would be interesting.
