Re: more and more and more solarplate
The exposure times are very close to what Jon suggests, 10-11secs for a 5K lightsource. This is much less than I would have usually have exposed the plate for (45secs). From the very quick test I ran, there is definitely a deeper black although the midtones don't seem to have shifted at all. With such a short exposure/washout, I was worried that it might be uneven but it's actually very uniform, even in a smooth grey sky.
I have never liked deep blacks or stark whites in my work, preferring some tone in the highlights, and detail that you have to look for in the shadows; the km73s give you that plate tone in the highlights. But with Jon's method I may have to be careful, for the blacks are so deep.
As I mentioned before, I've played with numerous combinations of screen and image exposures and every time, the best was always 50:50 (+or- 10%).

What effect did you notice with shorter washout?
Longley exposes the positive on KM73 for about 3 minutes (2.5 in summer sun) and then the aquatint on top for 1 minute. I find that an interesting combo of times...
