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...
