Identifying Large Format Film Holders - Trace Your Large Format Film Back To Your Notes

[@reedjones6405]

On the other side of that film holder edge, you can put a notch there for side 1 and no notch for side 0 of the holder. I may make a drill template rather than cut notches using the same system. Also it would be easier to drill holes in my wooden 5x7 and 8x10 holders than cutting with a knife.

On you're suggestion I just ordered Beyond monochrome 2. You didn't mention that both sides of the film holder must be notched and that there should be an additional notch to indicate side A and by lack thereof side B. Is this so?

[@Distphoto]

I have both sides notched but just with different numbers. For instance my first film holder is 1 & 2. Second is 3 & 4 and so on. So yes , I have both sides notched.

[@marcdeckard7064]

@@Distphoto That makes sense. Thanks.

What good does knowing which film holder you used, other than identifying a defective one?

[@Distphoto]

To me it has a lot of advantages. Right now I am testing dev and filters with a new film. This allows me to track every sheet back to my notes as multiple sheets look very similar and I would otherwise not know which is which. Also if a holder has a bad seal etc…

Maybe I'm missing something obvious here, but how does this numbering system relate to the film inside the holders? How is it useful to know what holder was used if the film is separated from the holder in the dark during development?

[@Distphoto]

It marks the film so you know what sheet was in what holder.

[@synaptophysin]

If there is a defect in the negative due to the film holder such as a light leak, you can identify which film holder caused the problem.

That’s a cool system

[@Distphoto]

Thank you! It helps a lot with figuring out what is what 👍

[@markholm7050]

Should the notches be placed so that they don’t line up with the notches punched in the film at the factory? Those are in the upper right. Should we make our holder number notches in the upper left or does it matter?

[@Distphoto]

Do not think that matters at all. Has not made a difference for me but you certainly can put them in the left 👍
