critique on infra article and more questions

["Christina Z. Anderson" <tracez@xxxxxxx>]

Thanx for the interest in critiquing my infrared article.  I received about
25 requests for it (was very surprised)(whew) and have received back about 4
critiques of it.  Please continue to send me back your input.
     Bertha raised an interesting question.  Does putting a red filter on
your lens INCREASE the amount of infrared light available to the film?  From
what I understand of filters this is not so, it just decreases the visible
light it blocks.
     Is there truly no difference with Konica with the 15, 25 and 29 filter?
     Do fluorescent lights in the darkroom that take a while to subside
truly not fog infra film if you turn them off and immediately start
developing, e.g. in trays in the dark?
     Should I not even recommend Rodinal as an infrared developer because
the grain is golfball size?
     It is so nice to have you experts here to bounce these concerns off of.
I do not want to xerox these notes for 40 students if there is wrong info on
them.
Chris
