So that at least there is no visible difference in pic quality?
The offical storage life by of pro slide is about 6 mths.
I was told that by keeping pro slides frozen (at -20c instead of 15c) help quite a bit, but still cannot keep them for very much longer (ie n years without degrading) as there is the limiting factor of high energy outerspace radiation that "expose" the film as time goes by and low temp doesn't help.
(there was discussing in NGs about how long can film be kept in liquid nitrogen or absolute zero temp, conclusion was not much longer than -20C)
If we can keep the film longer than I believe many ppl will order/order more bulk rolls.
I don't mind order 1-2 rolls if they can be kept for 5 years.
To protect the film from outerspace radiation (ie: alpha, beta, garmma), we need to use dense mass blocks to cut them out.
Anyone know where to get massive lead blocks?
Lead can keep uranium safe for ppl to carry, if I remember correctly just a few cm of lead can cut down these high energy radiation by a factor of 10. double the thickness means a factor of 100.
May be we can keep our bulk rolls in some of the core member's home, there we can keep them safe for n years where n>5. There must be someone having empty freezor space. Anyone sells ice cream here?
