Shuffling
- use trays one size larger than the print, e.g. 11x14 for 8x10 prints
- have an 4-5cm depth of solution
- don't use a "stop bath" since you're likely to put some of the acid into
the developer; use a deep water tray or circulating bath
- use a paper developer dilution that allows 1-2 minute developing, not 30-
60 seconds.
For the shuffling, the usual procedure is to:
- note the time, or set the clock
- put the paper in on top, one at a time, using a dry hand to put it in,
and a wet hand to make sure it's all wetted.
- once all the prints are in, stabilise with one hand, slide the bottom
print out and put it on the top, then push down to wet it all
- repeat continuously, until...
- when a print looks done, put it in the water bath & swish around for a
second or two.
- avoid more than 3 minutes in the developer to avoid fog
- after all prints are in the water bath, then you can transfer them, one
by one, to the fixer in the same manner (this time, you can let them drain
a bit). Or squeeze them together into a solid brick & transfer them all at
once with a minimum of attached water.
If something needs a little burning in, you can encourage the development
by rubbing the area with a finger. The extra heat and agitation will
encourage development. Just do it for a second or three every time you see
it.
To avoid developing alergies, and to improve the grip, you may wish to use
rubber or disposable gloves.
