I thought I didn't have enough trays...
You can _never_ have enough trays ...
Dev then water then stop?
Just curious.
The water bath is used to lower paper contrast a tad.
The technique is to over expose and underdevelop just
like film. However, with paper it can be hard to
underdevelop evenly because of the resulting very
short developing time. It is easier to get even under-
development if shortish dips in the developer are
alternated with soaks in a water bath. There is
(possibly) some effect from differential
developer depletion in shadows Vs. highlights.
Much the same can be done with very diluted developer
but very dilute developers shift the tone of some papers
to the red.
The vaunted A130 and G262 developers are just
slow working developers that give even, though incomplete,
development in 2-3 minutes. Developing to completion
in A130 - which takes about 6 minutes - produces results
identical to D-72/Dektol.
