Arista EDU Ultra 100

[tom_mccabe]

Good afternoon. all. I have a roll I shot as a test for an older camera. My go to film developer for BW is Ilford Ilfotech DDX. I can't find development times for this particular and developer combo. The Massive Development Chart lists 200 and 400 ISO but not 100.  It is just a test roll so it's not critical. I can't see myself buying and mixing a different developer for a single 35mm roll. My thought is to go with the 200 development time, which is 6 minutes at 1+4. Any thoughts? Has anyone out here tried this combination?

Thanks!

This link may be of some assistance, but it doesn't mention EDU Ultra 100, however 8mins would be a very good starting point IMO.

As far as I know, Arista films are repackaged Fomapan. The Massive dev chart has times for Fomapan 100 and Ilfotech DDX.

Thank you for the info!!!

I'm wondering why EDU Ultra 100 isn't listed for DDX when it's listed for other developers in The Massive Development Chart. Perhaps DDX is not suitable for Ultra 100

Selecting a few other developers, the chart has:

ID II 1:1 (6-7mins),

D76 stock (6-7mins)

Ilfotech HC 1:79 (13mins) 

Rodinal 1:50 (7mins)

all for EDU Ultra 100

To get the best results, you may need to buy a different developer.
