[APML] Tech Pan Developing Q

["Brian Larmay" <astrobri@ameritech.net>]

Hi,

I was talking to a photographer about storm chasing photography using BW
film and she said something that I thought might be interesting for
some....here is a snip from her response to some gweneral questions:


<snip>

Another good option for increasing contrast without increasing grain size of
the negative would be to selenium tone the negative (a type of
intensification) in a 1:3 dilution of Kodak Selenium toner and water, for
about 5 minutes, after complete fixing. Wash thoroughly after this. Keep in
mind that most of the contrast increase will be in the mid-tones through
highlights, so you want to make sure your cloud mass is exposed bright
enough on the film.

Ok..
So has anyone tried this or thought of this?
Any thoughts to how this might add or degrate to tech pan astrophotos?

Brian
