help needed: Glass negatives...

[Emil Schildt]

I just found in my house some packs of old glass negatives - unopened...

(Don't remember where I got them from...)

I'd like to try them, but I have no idea what iso to try - and what development to use...

Any help from you experts?

First is called "Eisenberger"

Second is Ilford "Auto filter plates"..

Third has only danish text:

"Extra rapide "Ideal"" ---

size is 18x24cm for all....

Could be so much fun to try them out...

You are going to have to experiment.
I would start with a test by exposing at EIs 3, 6 and 12.
Develop by inspection in D-23 with some benzotriazole added to combat fog.
If you aren't knowledgeable about DBI, start with 5- 8 minutes @70 deg.

heh - I am not familiar with D-23 and I have no idea what DBI means, so.....

But test I will..

Develop By Inspection
In this context, anyway. Michael Smith has a piece on it at http://www.michaelandpaula.com/mp/devinsp.html.

And Ken Lee has a section on D23:

Unless you buy it from the Formulary or some similar place you will probably have to mix it yourself, but it's almost silly simple and cheap. The pre-measured Formulary kit is NOT cheap, but is an easy way to try it out before you buy the components separately:

The collector in me says it wishes you would save these intact.
But if you must, try to get photos of something that would maintain it's unused value; like naked girls.

I'll settle for half-naked.

Gandolfi, I would use a two-developer stup for these old things: One low contrast developer, one high contrast. And develop by inspection, of course..

I have a good recipe at home, and I'll be driving home tomorrow. I'll see if I can find it!
