Ilford F.P.4. Plates.

[alexvaras]

Hi all,

From the same seller I got my Fotopan F 10x15 I got a box of 10 dry plates from 1967, Ilford F.P.4. panchromatic.

F.P.4. Dry plates from 1967.

First I got problems since they are quarter plates and my holders where too big so I found 3 Voigtlander ones for the American market and I just received them... Still a problem finding a solution to keep the plates in place in the SP-445, that's why the clip mark.

First shot is ASA5, over exposed minimum 2 stops.

Dandelion.

This test was to find out the correct ASA after 50 year and which is the emulsion side... next photo was taken with the emulsion on the other side so the walls from the holder at developing made strange and cool effect, but some parts where not developed at all. Shot as ASA 10.

My B.

As conclusion I will shot one more plate rating it as ASA 25 and placing the emulsion side correctly, it seems it's the matte side by inspecting by fingers. Soviets as not the same, normally the non emulsion side is pretty dirty from the paper it carries and only by orientation it's possible to know the emulsion side.
Any advice before next try is welcome

Thank you for looking,
Alex

Can't give you much help, as I don't know much about plates, Alex, but you are going in the right direction on your experiments.

Thank you, Phil, your words always take me forward.

I already know that previous effect happens and I think I can do it again with good quality, we will see...
Finally one well done, right side of emulsion and all in place I think.

Finally rated ASA 25, almost 10 minutes with D-76 1+1 at 20 degrees.

Incredibly well preserved this plates from 1967, 6 more plates to shoot.

Thank you for looking,

Amazing that you are getting such good results after 50 years, Alex. Bravo! Weston 80 is equivalent to ISO 100. Opening about two stops seems to compensate correctly for the age of the emulsion.

Beautiful result, Alex!

Nice separation from the background.

Umm, you might want to spell check the title of one of your birch photos on Flickr, Alex.
