Dear John,
I use the stuff made by Tetenal: they recommend that you clean and then=20
immerse the whole negative in the varnish using tweezers. I take a smaller=
=20
Muesli bowl, put the varnish in that and then pull the entire stip of=20
negatives through the varnish.
Then I let the varnish drip off over a corner, back into the bowl. Hanging=
=20
up to dry means kind of horizontal, so the varnish will collect on the=20
films sprocket hole or at least outside the image area of the film, you do=
=20
not want uneven thickness of varnish over the image area. So I take three=20
clothes pins and use those to hang the negative strip and three on the=20
bottom to keep things flat.
Seems to work for me. Do most of this in a well-ventilated area, I don=B4t=
=20
know about the Edwal stuff, but the Tetenal stuff produces heavy vapours=20
which will give you a full anaestetic if you inhale too much :-)
BTW I always thought the nose grease resp Vaseline trick was for the=20
emulsion side only if that side is scratsched?
Love
