    Tray processing vs Semi-Stand processing... an example

    Attached are two scans of identically exposed pieces of film in identical overcast lighting conditions.

    The one processed with conventional tray processing actually has a higher Contrast Index.

    Hoodoo 1 stand, developed Pyrocat HD 5M presoak, 1.5M agitation, 35M stand, 30s agitation, 35M stand...result 1.36 highlight density above film base plus fog
    This was the first ever film I processed in the Semi-Stand method, in those days the dilution was 1-1-175.

    Hoodoo 1 conventional, developed in ABC Pyro 1-1-1-7 for 22 minutes continuos agitation...result 1.53 highlight density above film base plus fog.

    The resulting prints from each are as dramatically different as the negatives appear here.

    Interesting stuff, Steve.
