I like April 29.  Jerry E.

April 29 sounds good to me too.
Guillermo, you had a very good disguise the day you dropped by! I never 
would have guessed that you were one of the pod people.

Re: [pinhole-discussion] Pinhole Day

Everyone seem to have persons to honor in selecting the Day of the Pinhole.
Some time in mid spring or mid autumn would be most fair to all locations on
the planet.  Since we have a great deal of energy gemerating at this time,
lets chose a date not more than two months away and not favor any particular
nationalty or culture.  Jerry E


I nominate Lord Rayleigh's birthday, November 12, 1842.

Re: [pinhole-discussion] Pinholes in my pinholes

2001-02-11 Thread Jerry and Katherine Green-Ellison
Larry...it is my guess that the inside of your pinhole camera is dusty.  At
least in my large format photography, pinholes in the negatives come from
dust settling on the film.  Jerry Ellison


Folks,
 I have been getting these tiny little pinholes in my negatives every once
in a while and can't figure where they come from. The negatives can be color
or bw and some I process, some I send out to various labs. So I have two
questions. First, does anyone have an idea of how this happens? Second, Is
there a way to plug the hole so I can print them and then color in the
spot on the print?

[pinhole-discussion] RE: stripped negative

2001-01-20 Thread Jerry and Katherine Green-Ellison
I used the method as Leezy described.  For you experimenters, I did find a
certain chemical solution that made peeling the emulsion from the paper
backing much easier, but I've forgotten which chemical.  A hundred years ago
photographers who used glass plates stripped the emulsion off all unuseable
negatives so the glass plate could be recoated and used again.  Then in the
1940s, pictorial photographers who made paper negatives discovered the
process all over again.  And in the 1970s, as far as I know, the procedure
was used mostly by people making scenic lamp shades from RC prints.  Jerry E




[pinhole-discussion] stripped negatives

2001-01-20 Thread Jerry and Katherine Green-Ellison
I am new to this website so I do not know if this topic has been explored
yet.  In the mid-1970s I built pinhole cameras and used RC enlarging paper
in the cameras.  After exposure and development, I stripped the RC emulsion
from its paper backing.  This made a very useful negative.  I had earlier
used this procedure in making scenic lamp shades from RC prints.  Jerry Ellison
