    How are you rating HRUs ISO?

    I'm going to start at EI 50 with HRU and Rodinal 1:100 for nine minutes. I can always adjust from there.

    I rate HRU @100 and develop in Pyrocat HD+, 2,2,100 by inspection.

    I used to shoot HR-T at 50 but gradually moved up to an EI of 80 or 100. I think 9 minutes in Rodinal will be overcooked but it doesn't hurt to try.

    Thnx Bryan and Jim.

    I think 100 is now a good starting point; I like to bracket so I'll try 80 or as 64 as well.

    I know highlight density builds really fast with XRay. Pyro PMK+ is my time tested soup. Also it will harden the HRU soft emulsion I hope?
    Also I have a gallon of straight Acufine I've been replenishing for a while. Might have a go with that.

    Roto trimming both of these films does not seem to make any scratches I can detect, which is good news. I did buy 8x10 Cesco white smooth bottom trays so that should work? We will see. Maybe I'll be some XRay hangers and fire up my 3 1/2 gallon 3F tanks for basket line?

    As far as printing, I have a new split-filtering contact light source that uses 6x6" Multigrade filters. I think these XRAY negs would benefit from split-printing?

    Hi Corran,
    6-7 min in Rodinal but for what sensitivity for the film: 100iso?

    Read the rest of the discussion in the last couple pages. 50-200 depending on the person, I go for 80-100 myself. You may need to adjust for your sensibility/process.

    I have my first 4 sheets of Fuji UM-MA loaded into holders. My plan is to shoot at ISO100, develop in Pyrocat by inspection. First inspection will be at 5:30, since my "cold" water is in the mid 70s in the summer. Final prints will be on Grade3 Azo, Grade 2 Lodima, or Grade 3 Lupex depending on the negative contrast.
