Let me know when you get tired of my film testing.

When Larry opened this post I replied indicating that I was planning to return to traditional b&w film and processing after years of using  Ilford c41 b&w. I seem to remember (not sure - having a senior moment) reading in various posts that films of different names may be from the same manufacturer.

If that is true, does anyone have a list of who is making what? I certainly don't want to test the same film more than once. I will be starting with slow and medium speed films using diafine.

 Well Arista films from Freestyle Are known to be rebranded. The .EDU is Foma. EFKE and ADOX are the same as the names have problems with copyright in some countries. Aristia Premium is Kodak the 100 is Plus-X and the 400 is Tri-X. Legacy Pro is Fuji The 100 is ACROS and the 400 is Neopan 400. With Ultrafine films I have discovered that the new eXtreme 100 as they call it is Kentmere. Not sure what the 400 is but I do know I don't like it. I probably know more just can't think at the moment but others please chime in.

 Now when we get to Rollei films they are all over the board as they cut down many other still produced films and give them a Rollei name.

Thanks Larry.

That was really quick and very helpful.  It'll save me a few dollars when buying film.

Well you are welcome I hope others chime in. What film was you thinking of starting with?

[flatop222]

I had not made up my mind yet. If you have some recommendations for films that respond especially well to diafine, that's where I will start.

Foma films are all fine at box speed in Diafine. Tri-X gives you a speed of 1000-1600 in Diafine. I shoot it at 1250. T-grain films lose speed in Diafine.

 Here is the diafine chart from the MDC.
