I use photoflo also.
Should I be worried about dust drying on the negative,
if it is not enclosed in dryer.
To avoid dust, I made a narrow box (laquerred wood, door at
the front), with 2mm wires for hanging the films on.
At the sides (top & bottom), there were openings, covered with
To speed up the drying, I later added a computer cooling fan
that pushed air in, through the top dust filter.
When the fan quit working, I attached two 100Watt bulbs at the
bottom-side, plus a hood above them, so they don't get dripped
The bulbs were connected in series, so each gets half the voltage
and never burns out.
The warm air, going upwards from the bulbs, speeds up the drying.
"Enclosed shower hanging in the middle by wire with the
shower door closed. Does a pretty good job keeping dust off."
This can work where there's little dust all year long.
Where I live, there're a few sand storms per year, so a drying
cabinet with filtered openings at the top & bottom is a necessity.
Once it's a closed cabinet, and air movement is quite restricted
by the air filters, if you cannot wait for too many hours, the air
should be moved & replaced somehow - typically by a small fan,
or by heating the air at the bottom a bit.
"I use photoflo and a squeegee."I've always wiped films between two fingers, which are first
wetted with photoflow.
