    Hi everyone,

    I am a newbie trying to make 4x5 negatives for graphic arts purposes with rollei ato 2.1 previously known as genius print film.
    I am using a speed graphic.

    My trials today came out very low contrast and almost washed out of tone completely.

    I used:
    flood lights 24w (claimed to be equivalent to 120w)
    Ilford pq to develop under safe light
    Development for 5min
    Jobo tank with CPE2 and reel
    Used f5.6 and 6 sec with iso 25 as suggested by the light meter (tried a stop up and down too)
    The original target consists of bold black text and lines

    Can anyone see any obvious faults in what i am doing?
    Thank you in advance.
