Not to put you to more work, but can you do a quick Reciprocity study using the EG&G at different exposure times?

I think it would be valuable to show how different the gradient might be from a home-made "flash" sensitometer used at low light output (for example time might be 1/10,000 second at lowest setting).

I'd do the test but I don't have the acetate filters to balance the different speeds, and I think you made a set...
