Not really a heart attack, just a mild moment of "uh oh".
Tonight, I just finished processing two rolls of 35mm. I have a notebook in the DR where I keep tech data on everything, including developing times.
I had already started the timer when I realized I had set it for the time for Delta 3200. However, :o I was developing TMax3200!! Fortunately, I had that time in the notebook, and it is actually longer than Delta.
Whew ... Just added the time to the timer and all is well.
Hardly my worst screw-up. :rolleyes:
