Manuel,
Two drops of the standard Na2 solution (20%) would give a *radical*
increase in contrast. This stuff is very powerful. I suggest you dilute
some of your Na2 with distilled water into 10% and 5% batches, then do some
experiments adding just one drop to your normal sensitizer mix and see what
you get at each concentration level. You don't need to substitute from your
standard mix, just add a drop of Na2.
