MacBeth TR927 densitometer

Chuck_P · Jul 10, 2007

I've been doing some searching for a densitometer and was wandering if anyone has any knowledge about this model as seen on ebay (item #: 150139323432 in case you want to take a look). Will be used for non-stained negatives only and I believe that it has a white light setting, just from the photo, but not sure and of course, I'm concerned about ease of calibration as I have seen in the forum search that calibrating older models can be problematic. I would appreciate any information that you may have?

Thank you
Chuck

Chuck1,
I have one and calibration has not been an issue. I have a pdf of the manual on my site - you can download it here.

Chuck,

You will see from the manual that the standard Macbeth (sic) TR927 has Status T colour filters, Ortho and UV, but no visual channel. Whether this is important will depend on what you want to use it for. If you are just using it for unstained silver-image negatives it won't matter.

Best,
Helen

Helen,

I was only able to print out first three pages of the manual before my computer crashed this morning, but on page three it indicates the "Visual/Ortho" filter together in the same column and labled as "white". Perhaps I am reading this incorrectly, IDK.

Juan,

I don't know what is causing it, but my computer crashes everytime I try to access the manual from your site. But I am understanding that you use this densitometer for your black and white work with non-stained negatives?

Thanks

Now I'm not sure that it's a 927 that I have. It could be a 903. I'll check at home tonight. I use mine for both stained and unstained black and white negatives to be used on graded silver paper. I make my measurements on the blue channel.

PM me your email, and I'll send the manual to you, if you'd like.

I'd look for a TR-924. They aren't rare (or expensive, generally) and have both Status A and M.

Helen,

I see what you mean now with the particular channels as I was looking at it incorrectly. I will be using it only for un-stained silver negatives, so do you mean that it will not matter which channel is used? Which particular channel should be used for un-stained negatives?

Thanks
Chuck

Isn't status T is for offset printing and not for negative?
