So citric acid is only necessary to preserve sensitized paper, not the
solution itself? What I'm trying to figure out is: if I decide to make
say... 500ml of silver nitrate sensitizer solution will it keep
indefinitely? or should I definitely add citric acid to the solution if
I want to keep it for long time? - finishing 500ml sensitizer will take
SOME time ;)

I will try three types of negatives:
1. 4x5 HP5 negatives (from a pinhole camera) exposed E.I. 250 ~ 320
and overdeveloped by 30% (according to E.I. 400 times, in ID11) - do you
think this will yield the desired contrast range?
2. Enlarged negatives on lith film (using Liam Lawless' method as
described by Ed Buffaloe) - some testing and voila!?
3. Enlarged negatives on inkjet transparency media.
According to you, which method is easier to obtain a negative with a
wide contrast range (~ 2 - 2.4)? Any other recommendations?

I see... but obtaining gold toner is hard in my area (also the toner
is pricey and If I remember right there's some sort of fussy
replanishment procedure which I found difficult). I like the untoned
color of salt prints - warmer is better for me. Will selenium toning
preserve the print without bizzarely altering its hue?
Thanks again,
Loris.
