I would like to mark my 4x5 negatives with a file number in the blank area created by the sheet film holder end flap. So obviously there is not a lot of space to work with.
I have been working with an Ultra Fine Point Sharpie. It kinda sorta works but the letters and numbers are not solid black so the information likely will not show very well on contact sheets or scans. Also, I think if I tried to use film cleaner the file numbers would come off.
I believe I read somewhere here or on the Intertubes (so it must be true) where one photographer uses a technical pen such as a Rapidograph filled with India ink.
What do other LF photographers here use to permanently mark their negatives?
Would India ink come off if film cleaner was used?
I would appreciate any suggestions.
Thanks,
Terry
