Questions/Intro

[jeffs@xxxxxxxxxxxxx (Jeff Spirer)]

I am new to the list and have a few questions.

1) For IR, I normally use HIE in 35mm, but my lab recently gave me Konica
750 in 120 format.  The sheet is in Japanese, Konica's web site ignores IR
film as far as I can tell, and I just can't find the info.  Questions are
what filters with what general EI range.

2) For my Rollei (TLR), the only red filter I have is the standard one for
b&w work despite looking everywhere for a Rollei IR filter.  (I did find
one but the price was ridiculous.)  Also, the Rollei IR filter is opaque
(one reference says the type for the opaque filter is Agfa No. 83) and I am
wondering if this works with Konica 750.  Also, what type the "normal" red
Rollei filter is would be useful information.

3) I have an old Rollei brochure that came with my camera that has an
interesting statement: "To compensate optically for the required focuing
difference, the infra-red filter is ground to act as a weak lens."  Bob
Salomon is unable to locate any confirmation that this is true - I even had
to fax him the page from the brochure.  Does anyone have any info on this?

4) So finally, if the above is in fact not true, since the Rollei does not
have an IR focusing mark, what is the preferred method for focusing a
Rollei with IR film?

- Profession/Study: Day Job: Web Commerce.  Night Job: Web Music Sites.

- Country: USA

- Personal history of photography Started when I was around 10 years old
(early 60s) with an Argus C3.  My father had built a darkroom in the house
that we used.  Never had a darkroom after I moved out, but continued
photography anyway.  Still going.  From time to time I have sold photos,
mostly people and concert shots until recently.  Now I am doing "beds" for
CD booklets.

- preferred subjects: Mostly abstract stuff.  Occasionally people or
flowers.  Extreme closeups.  And my kid.  I used to do rock and jazz
concerts but I burned out on it and there wasn't a lot of room for
creativity, although the pressure made it exciting.

- materials (film, filters, paper, chemistry): In 35mm, I shoot mostly
Scotchchrome 1000, which I filled my freezer with when it was discontinued.
I push it two stops and cross process to negatives.  I also use HIE
occasionally.  With 120, I use mostly Tri-X and NHG.  Because I have
neither the time nor the space, I don't have a darkroom but I have a
printer who does a pretty good job for me.

- format (35mm/medium format/large format):   35mm and MF.

- Other strange hobbies: Weird music.
