[APML]: Chuck Vaughn's Prints in S&T

[Frode Tyholdt <frode.tyholdt@fys.uio.no>]

    Here's a part of Cuck's astronomy page:

        Another technique for contrast reduction breaks the number one
        rule for Tech Pan - Always develop the film in D-19! 
        For bright objects try using HC-110 Dilution B and develop for 10
        minutes. This gives the same film speed or slightly faster as does D-19
        but with a lower contrast index and therefore an easier negative
        to print. I've found it necessary to increase the exposure
        time of the negative by about 50% if the object is not real bright in
        order to get a bit more density.
        It is also possible to develop Tech Pan in D76 for 10 minutes for 
        an even lower contrast index at the cost of lower film speed. 
        It is necessary to double the orignal exposure time to get good
        density on the negative. D76 gives a very nice tonal range and an
        easy to print negative. 



    Do you use the same hypering time for film you're going to develop in
    HC-110 and D-76 as for D-19? One of the main reasons for using D-19 is
    as we all know to minimize chemical fogging so I've never used
    anything else. So I just want to know if I can hyper my 2415 just
    like before and use your developing times for HC-110 and D-76.
    (I know that I may have to adjust them a little bit in order to
    match the hypered film I use).
