    Densitometer Manual?

    Hi all - just ordered a Macbeth TD500 transmission densitometer on the auction site. While I'm waiting for it to show up, I was wondering if anyone could point me to a manual?

    I have a TD-504 unit with manual. I am not sure what the differences are from the TD-500.

    To use it you turn it on fro a few minutes first so the light source can stabilize,. Then I zero the reading on the film base between frames, then read off density above film base.

    I checked the gain of mine with a step wedge. I found it made sense, so I have never needed to fiddle with the gain or slope potentiometers on the back.

    Mine has a fillter barrel for c-41 readings. I use the yellow setting for reading B&W films.
    my real name, imagine that.
