All film was Fuji HRT
Dev Rodinal 1:100
1000mm used in trays with Glass on the bottom
I was bemused at the Portrait results possible causes
Dark area cause 1. light leak( wrong)
Enlarger with condenser showd 1 stop of light difference from cenre to outside of frame
This kept me occupied for several months testing and almost getting the light to 1/3 stop more in the centre of print.
KI shots are next these above I considered bad,should see the dark area on those.
