120 numbers

[Tim Gray]

I just developed my first roll of 120 last night. Kodak 400TX. The camera works

Anyway, on the bottom edge of the film are the frame numbers 1-12 and little arrows. On the top is Kodak, 400tx, and another set of numbers, 41-53 (if I recall correctly). They have roughly the spacing of the frame numbers. What are they for? Do they mean anything?

These numbers are for ordering prints from MF negs. IIRC, the 41-50's correspond to 645 format. The 1-12 to the square format.

Secret code.

You are correct. I have worked with square and now mostly the 645 format and the numbers do line up in that fashion.

YAY!!!!!!!!!!!!!!!!!!!!!

Do I get a cookie?

 

[Ian Grant]

No

WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA HAAAAAAAAAA HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

You had to ahve seen that one coming, buddy.

 

[Tim Gray]

Ahh, makes sense. Seemed odd that it starts at 41, but whatever.

Man I want cookies now.

 

[Christopher Walrath]

I never understood it myself. That bit of film history is beyond my pervue.

 

[Tim Gray]

4 for the 4 in 645? Who knows. Maybe PE knows.

 

[Christopher Walrath]

It fails me but it almost seems that it was in fact a Kodak piece of literature that set about the custom.

I didn't find this in my previous search:
(there was a url link here which no longer exists)

 

[Ektagraphic]

Do Fuji's films have the same numbering?

 

[Tim Gray]

It doesn't sound like it, but I don't know for sure. It's not mentioned in their data sheets.

 

[polyglot]

Acros has frame numbering from 1-18.

You wouldn't want two different series of frame numbers starting at 1.
So why not 41?
