Re: Little white spots and static electricity

["Thomas H. Hogan" <flzhgn@xxxxxxxxxxxxx>]

Dear Ian, Angela, and others,


I have encountered this "pinhole" phenomenom with HIE film
several times when I used tap water.  I suspected that some
suspended particle perhaps Iron  from rusty old pipes was
a possible cause.  I had always used de-ionized (reverse osmosis)
water which was available on tap most places where I did photography.

There was a post from a Brit. awhile back that mentioned iron in 
the water and even further back someone mentioned chlorine as
a possible cause.

The question I'd like answered is:  has anyone experienced the 
minute hole in the film ("pinhole") problem when using distilled
or de-ionized water for all solutions and rinsing?

BTW,  I'm looking for a job as a biological science research
    technician.  If you know of anyone who might need a technician
    with my skills (see resume on my home page) please let me know.
