frame spacing

The next time you have 120 developed, ask them to return the paper backing.
They sometimes get this request if the photographer has made lengthy 
notes on the outside of the roll. My lab doesn't raise an eyebrow.  I 
have a handful of them here as an aid for camera building.

There is a single piece of tape that holds the film to the paper. 
When they develop the roll, they tear the tape. Half stays on the 
film, half stays on the paper.  If you get the paper back, you can 
precisely align the two torn pieces, and see exactly where the frames 
line up in relation to the numbers.

By the way, there are no markings for 6x12 or 6x17. There are just 
6x4.5, 6x6, and 6x9 markings, on Fuji film anyway. You would have to 
skip numbers to get 6x12 and 6x17

I'd be happy to give you a couple of empty paper leaders if it would 
help, Brian.

Y2K advisory:  Nostradamus was wrong in July, and GPS didn't collapse 
in August.  All that's left are cynical marketing and scams.  At this 
point, anyone who cries "end of the world" is trying to scare you 
into buying something.

Computer bug?  Get real.  Think about it: For years already, most car 
and house payments have extended past the year 2000. But have you 
heard of an actual glitch of any kind, anywhere?  Your bill has been 
correct to the penny, right?  No major company is stupid enough to 
let Y2K cost them money.

Don't fall for empty Y2K hype.  Don't do anything nutty.
