I found this Excel program hidden away whilst doing some house keeping.
Thought I would put it out there again, but don't know how to add an Excel file.

For calculating ideal exposure length.

Google drive and share the file?

Thanks Gents for the kind words.

Ray: Good tip.
Here is a link to Google drive where I placed the file.
It is for Excel spreadsheet.
Let me know if it works or not.

Thanks Peter. Got it. Some of those units are a challenge and not really sure what i am aiming to get. Interesting to try though. I like the "test image and measure the histogram" system but this explains the result.
