I was recently asked what type of writing device we use to mark the catalog number on the edge of our film. I had not given it much thought since we have been using the same pens for marking film for many years. I have heard of people using various mechanical pens and India ink. Some say they use a common Sharpie. There are numerous ways to do this, but the easiest and most effective way I have found is to use a pigment liner pen.
Specifically, I have used a Staedtler pigment liner pen for years. They are clean, easy to use, make very dense letters and numbers that easily show up on proofs, and are filled with permanent black ink. The ink used is lightfast and will not fade. One nice thing about the Staedtler pigment liner pen is it will not dry out. The manufacturer says, “The unique cap-off feature of the ink enables pens to be left uncapped for 18 hours without drying up. Even when left open during long breaks in writing, they remain ready for action without delay.” They also last a long time. We have not had to buy new pens in years.
The Staedtler pigment liner pens are available in nine writing widths from 0.05 mm to 0.8 mm. My favorite sizes are the 0.3, 0.5, 0.7 mm widths. I use the smaller diameter pen for small film where the clear edge is very narrow. You still get very legible writing along the film edge that prints well on the proofs. I prefer the larger diameter pen for the really big film. These have worked well for me for over 30 years, and should work well for you also.
Here are a few things I have learned over the years that may help when using these pens to mark your film. I always mark my negatives on base side opposite the emulsion, this way the file number prints correctly on the edge of prints and proofs. Be sure to let the ink dry thoroughly before you place the film into a storage sleeve. It should only take a minute to dry. I have found that if you make a mistake, you can remove the ink using a cotton swab lightly moistened with acetone. And, one more thing; the biggest mistake you can ever make is not using a filing system for your negatives. If you choose to mark your film on the edge, these markers will do the trick.

If you are lucky enough to own a Calumet Shutter Speed Tester, you know it is not exactly ideal for testing large lenses and shutters. I have owned one of these handy little devices for over ten years. I performed a modification/upgrade near ten years ago that makes the tester much more suited to testing large lenses and shutters.
