A note about developing TP in a small tank.....
For D-19, HC-110 and D76 you do not want to invert the tank, only spin the
reel slowly once every 30 seconds or
you'll get uneven and/or over development.

Well that solves one of my biggest problems.
I always seem to get one half of the neg darker then the other half and the
widefield shots of the milky way I take...it can be quite the burden to
rubberstamp for flat fielding
Also..the bubbles... pour it in b4 eh'?...makes sense.
Now what about the water rinse or fixer?
Do these cause bubbles too, or is that just something I need to be concerned
with while developing?
