Default numbering film holders

Hi - I have decided that I ought to start taking notes for each LF shot I take. Obviously I will have to reconcile the notes for each shot with the sheet of film when it is processed.

I have carefully numbered all my film holders (on the outside) both sides odd and even. However I am stuck when it comes to identification when I put the sheets of film in the tank for processing as they get mixed up. I found details of this system:
http://www.jbhphoto.com/articles/filmno/filmholder1.htm
but I think it is a bit over complicated - I was wondering if I could use an 8-bit binary system numbering from 0 to 255 although that could possibly be a bit complicated to read as well.

I thought I would post here and see if anyone else has invented a better system I could use.

The Grafmatic film holder has a small number at the edge of the magazine that is changed each time the dark slide is pulled and I wonder if this has been adapted for dd film holders as. I don't know if the Fuji film holder (I cannot remember its name at present).

I have about 15 holders and would like to continue the numbering scheme to include my 10x8 holders.

Thanks in advance for any help

PS May I see some of you on Saturday at Silverprint / Trevor Crone workshop?

Ralph Lambrecht uses the binary system in his book 'Way Beyond Monochrome'.

I have adopted Ralph L's system - he recently posted on the other forum site a PDF describing his method in detail. It is a pretty simple and elegant method.

I just number my 4x5 holders 1A/1B, 2A/2B etc. I make a written note of each exposure and its darkslide number. I then place the exposed film in old film boxes which are labelled for their appropriate development, N, N-1, N-2, N+1, N+2.

As I've only got 8, 8x10 double darkslides, I've just numbered them 1 to 16. And again I just make a note of the DDS number and its appropriate development and put them in the required box.

Looking forward to meeting you on Saturday

Your system may work with individually developed sheets of film if you note there position within the boxes, but the original post refers to the problem of getting sheets mixed during development. I think that the film has to be identified to it's film holder in some way.
Is it possible to drill a small hole, or to file a notch in the edge of each holder in a unique position to allow later identification of the DDS?

I'll second the Ralph Lambrecht method. I have my DDS done that way.

Please give an outline of the method for those that haven't got his book, and for those like me that are too lazy to go downstairs and find it.

You mean I have to get up and look for mine because you are too lazy??

It is a method of using the binary numbering system to file notches in the bottom hinged edge of the DDS relative to one edge. At the same time you prepare a template which is then used to identify the number later. Harder to explain than do.

This is his pdf from another site:

Because you took sooooooo long to reply Bill I had to make the arduous journey to my library to read the chapter.

Pages 278 to 280 contain the details for those that want to read it, and it does involve notching the edge of the film holders. Such marking will also help you to identify a faulty holder immediately, so from that point alone would be worth doing. I suggest that off-setting the notches to one side may make them easier to read from the exposed film.
