Paper emulsion gamma values, please?

IMHO too many people underexpose! And, they are not fully aware of it either.

I remember a Kodak representative showing me a panel of prints from -2 to +10 stop exposures. The '-' prints where all terrible. The '+' prints got better with exposure. Amazing!

Richard Zakia showed a nice example of it in one of his books. I spoke to him recently, and unfortunately, he has lost the originals, but fully approved of the examples I published in WBM2 (attached).

Some things are really simple, too simple, in fact, to be appreciated.

Very nice Ralph.

A while back I posted a series of Portra VC exposures at ISO 25, 50, 100, 160, 200, and 400. Same thing.

Hi Denise.

Happy (if belated) New Year!

Perhaps its crusty synapses but I really have read his series...
and, over the years, I have even owned two complete sets!!
but they and other goodies were stolen from me,
so now... my Adams Engine just limps along on fumes.

Ray,

So sorry to hear about losing your books. Ouch! Now I hope even more that you find yourself a set of Adams', and any of the other books lost that you considered important. Photographers cannot live on fumes alone!

Ralph, Denise

Thanks.

Denise,
They are very well written and a pleasure to read and learn from,
but I doubt I will replace them anytime soon.

Try the attached for starters, but it is only a rough guide for a normal subject brightness range without expansion or contraction development.

Ralph,

I'm having shadows in Zone I 1/2 of a stop more dense compared to your table, midtone gets higher about 1/3 of a stop. I think that is more or less along your line of recommendations? Highlights, I'm not sure, characteristic curve I'm getting ends at higher densities.

Julia

It sounds like you whole curve is a bit higher than mine. Keep in mind, my film densities are relative not absolute densities.

 

[Julia]

Ralph,

I measured subtracting the fog density, that's relative, right?

Overall thanks to the advice I got in this thread, and books recommended my printing is getting much faster. I'm figuring out dodging and burning now (using masks) based on index print densities vs. densities I want.

Thank you all, Gentlemen.

Ralph,

Yes, it is.
