RE: digital neg curve calculator
All this does is take the densitometer measurements, sets the endpoints, and
interpolates between them to get the correct values for the transfer
function curve points at 0,5,10,20,....% to straighten out the response.
This is pretty simple to do it's just tedious, hence the spreadsheet. I'm
not sure what all Phil's program did.

Does this program work anything like the Plotter program of Phil
Davis. I have used the Plotter program for many years and it works
very well but it was designed with an antiquated program language and
the resolution of the print-outs is that of the old Apple dot-matrix
printers. I would like to find something that would allow me the same
features as Plotter but with more sophistication in printing.
