Hi Tim,
Thank you for taking the time to answer. I will have to spend more time
in the darkroom to get something I like, but following your suggestions
helped to get a bit closer.
Cheers,
Manu

Hi Manu,
Maybe the instruction leaflet has been re-written but the LD20 leaflet I
have just looked at says
'start with a relatively strong solution, for example A 1+9 and B 1+9.
It then suggests you may increase the dilution up to 14 or 19 parts
water to change the effect. I believe the instructions initially were
drawn from my book.
The dilution has a marked effect on the result and much more so with
some papers than others (Fomatone MG being an example of a paper that is
especially dilution sensitive) so if you have the patience and enough
time you can in theory take dilution to extremes.
There is no right or wrong here really, as long as you get the effect
you want. Some printers like the effect of very strong and fresh
solutions, some prefer old and dilute and the results are very different.
Pepper fogging was a major problem with the Sterling Lith paper (also
marketed at one time as Fotospeed Lith) That factory closed years ago
and pepper fogging either absent or is only a minor issue today with
most papers, so don't worry about it unless you start getting it, which
you may never do (depending on the paper and how you like to process).
The extra sulphite must in any case be used with care or it can kill the
infectious development that you must have for the process to work.
