My old MacBeth densitometer was getting a little wonky so I just bought an Xrite 820 from ebay and I think I made a mistake. I retired from hi tech in the hope that I would never again have to read a turgid manual. Holy SMOKES! All I want to do is find the density of test strips on black and white negatives. I think that this machine probably solves the four colour map theorem while making coffee. It is wAAAAY over my head.

Does anyone else use one of these for the very limited purpose of black and white negs? I could use some advice.
