I recall that this trick was recommended to determine printing time.
Dunk paper in developer, wipe off excess developer and expose. The image
would start gray and darken. Eventually the image would turn black. The time
it took to turn black was the time it needed to be exposed. This worked for
graded paper, not for variable contrast.
Then clean up the mess on the baseboard.

I have had some success in getting a self masking effect with
conventional paper when enlarging by soaking it in developer before
exposing it under the enlarger. The limited amount of developer which
is absorbed in the paper means that the maximum black that you will
get under the enlarger is constrained. I think this is a tip I got
from and old book on using paper negatives, but as I haven't
completely unpacked after our move back to Ireland, I cant check it at
the moment.

I had forgotten this old trick. It does work. I don't remember the
title of the book I first saw it in, it was not about paper negatives
but was about tricks in photography. I am pretty sure it was published
by the American Photographic Book Publishing Co. of Boston, who also
published _American Photography_ magazine, a great bastion of
pictorialism from about the mid-1920s until the early 1950s, when it
died. This company published a lot of good books on photography during
this period. They also published the _American Annual of Photography_. I
have a collection of both the mazine and some of the annuals but all are
in storage.
