I don't want to do any calculating in the field. The exposure disc is a good tool, but having to place it in the scene is a disadvantage, especially in the field for found and delicate foliage shots, etc. I prefer just to consult a chart.
I've got my exposure record book with me in the field and that has charts for bellows extensions for all the lenses I commonly carry (plus reciprocity adjustments, filter factors etc., etc.) I only have to measure and look up my factor. I'm attaching the charts here for those that may find them helpful.
There's one chart in mm and one in inches so you can measure how you like. Feel free to copy, modify, whatever to suit your needs.
Best,

Very nice Doremus and I mean that 2 ways.
Beautiful chart well sized to be usable on a phone or printed. Nicely done!
A wonderful gift and accommodation for metric or imperial practitioners. Nice!
Thank you!

Thanks Doremus for sharing the chart that you developed. I appreciate your kind generosity, and this tool will help many others for a long time!

Another cheer for Doremus' chart, which is now where my phone can always find it. Many thanks.
