Exposure - 1/500 sec at f4.0 - Hand-held
There is still a hint of uneven development along the bottom of the photograph and the negatives could use a bit more time in the developer... seems 210 minutes is not quite enough.
Here is what I did...
I use a Jobo 1520 tank... so some of the steps may make more sense if you know this.
Position reel of film on the tank center tube so it is in the middle of the tank...
Pre-wash film until rinse dumps from tank clear and without any stain or dyes...
Mix 8ml of Rodinal with 800ml of room temperature water...
Fill tank completely to the top, full and running over...
Put on lid with center portion raised...
Thump tank heartily 5 times to ensure all air bubbles are removed...
Push center of lid down until developer starts to leak from under lid to ensure there is no air in the tank...
Invert slowly 10 times...
Thump to dislodge any possible air bubbles...
Tape around the lid of the tank to ensure it will not leak, black electrical tape works perfect...
Every 30 minutes turn tank upside down and thump to dislodge any possible air bubbles...
So tank spends 30 minutes right side up and 30 minutes upside down...
Do not swirl, agitate, or do a full inversion, this help ensure even development...
Dump developer at 210 minutes...
Water bath, stop, and rinse.
