Just received from Lodima Press the San Francisco Portfolio of Brett Weston. The quality of the 10 print reproductions is outstanding. Having never seen a Brett Weston print in person, this will be a good substitute.

For the record, this is the post that began this thread. Note that it is about the reproduction quality of the San Francisco Portfolio.

Lee, I think that the Quadtone uses 2 blacks, 2 greys and a 600 line screen. I haven't looked at the book with a loupe to see if the quadtones are double hits or if they have some sort or moire. But I may tonight.

I am extremely happy with the quality of the photos in this portfolio.

You'll need about a 20X loupe to see anything. At 8X you can't see any screen at all.

You may be right, but I used to look at stochastic distributions and 200 line screens using a 4 or 6x loupe. I'm sure that I have one of my old printing loupes around somewhere, it might be a higher magnification than my photo loupe. I guess that I could try the reflective Densitometer on it as well.

Does anyone have a known calibration strip that I could use with my MacBeth RD? Or does anyone know where I could get one without going broke?

I don't know if this is still of interest or not.

I have read dmax on the Lodima book Edward Weston Life Work. The highest dmax was 2.33 (Cabbage Fragment and Cypress Grove Point Lobos).

By comparison I have a copy of the Amphoto book of Brett Weston Photographs of Fifty Years. The highest dmax in that edition was 2.15 (Garrapata Beach).

Additionally in the Portfolios of Ansel Adams the highest dmax was 2.08 on Portfolio V plate X.

Donald,

You don't happen to know the ranges on those examples do you?

Don,

did you measure density or dot? I would think dot would be more appropiate since it is a photograph and a 1/2 tone of sorts.

Lee,

I measured reflection density since this is what Michael Smith and others were discussing.

Michael Smith stated, I believe, that he was able to consistantly reach a dmax of greater then 3.00 on the reproductions in his books. Some people seemed to find that representation to be questionable.

I think that reflection density would be a valid measurement of the tonal depiction of reproduction. It would be as valid as that obtained on a photograph...dot measurements may be more valid in tracking printing process and the results obtained.
