"6X6' and "120" and don't forget 2 1/4 X 2 1/4 :-)

DEAR JANET,
Yes, initially it can be confusing but the terms "6X6' and "120" are
often used interchangeably. By the way, I love your cell phone's spell
check which rendered Hasselblad as "hassle glad". Those cameras could,
indeed, be a hassle sometimes (when they jammed, you had a very expensive,
useless box!!!) but I was always glad I kept a second body and back up
magazines and lenses. So hassle glad, indeed! LOL!!!
CHEERS!

Thank you for your reply, Bob. I was confused when I saw people referring
to my negatives as 6 x 6. I was glad you said hassle glad. Then I knew we
were in the right lane.
Yes, I know what you mean about the quality of the larger negative. That's
why it's a little frustrating to me to try to get a large print when my
larger doesn't seem to be cooperating. I'm going to try another enlarging
lands and see how it goes.
Your body of work certainly sounds interesting!

DEAR JANET,
The difference between printing from a 35mm neg and a 6X6 neg is
amazing. Though I shot lots of b&w fashion and celebrity photos with my
35mm Nikons, I tried to shoot with my 'Blad as often as possible because
the results were MUCH more beautiful. And it isn't only sharpness. As you
are enlarging less to any size print, you have more "pixels" (grains) per
unit area which, according to communications science, allow more possible
grey scale levels...i.e. smoother tonality. About 5 years ago, I had a
show of mural sized (up to 44X60 inch) prints of the celebrity photos I
shot for Interview, Paris, German, and British Vogues, Town and Country,
etc. The 35 mm Panatomic X negs scanned and printed very well but the 6X6
Panatomic X negs (shot with my 'Blad; mostly 120 mm and 80 mm lenses)
produced stunning prints, by far superior to the prints from the 35 mm
negs. I could count Jodie Foster's eyelashes in a full length photo and,
as she was wearing a white shirt with a black double breasted blazer (a la
Veronica Lake), you can see tone and texture in both the blacks and
whites. And don't let anyone tell you it makes no difference in 8X10 or
11X14 prints. That smoothness of tonality is soooooooooooo obvious even in
an 8X10!
CHEERS!

Yes, when I asked about the stain on the film that was 35mm film. I use a
50 mm enlarger lens for that film but I changed to the 80mm for 2 1/4 x 2
1/4 film.
If I would want to make an 8 x 10 print with a wide border I would have to
crank the head up so high! It seems to me the quality of the print would be
better if that enlarger head (if that's what you call it, I'm not at home
where I can look in the book that came with my larger and I obviously don't
know the vernacular) were not so high up. To get a smaller print that head
is so far down and close to the paper that it's really hard to get the
focusing aid under it. Maybe the 105 mm lens will help, as suggested.
Printing from that larger negative is, I understand, supposed to be a
delight but it frustrates me to the point that I have at times considered
selling my Hasselblad. But it occurred to me that the camera is not the
problem but that perhaps I am using the wrong enlarger lens.

You need to clarify what you want. Keep in mind that if you change
focal lengths you need to adjust the condenser to match. The condenser
should focus the light source on the entrance pupil of the lens. For an
enlarging lens the entrance pupil is on the condenser side of the lens, not
the print side. The purpose is to even out the illumination on the easel.
A longer focal length will require more distance between the enlarger
head and the paper for the same size print, a shorter FL will allow a
shorter distance between head and print.
The illumination of shorter focal length lenses will not be as even
across the print, long FL lenses will be somewhat better than normal.
Your question about film stain indicated you are working with 35mm film.
80mm is "normal" for 2-1/4 x 2-1/4, it will require more separation from
head to paper for a given size print. "Normal" for 35mm double frame is
about 50mm, which will allow larger size prints than the 80mm for a given
column height limit.
50mm will require an adjustment to the condenser. I do not remember if
the Durst enlarger has a continuous or stepped condenser adjustment or uses
separate condensers but most condenser enlargers have pre-sets for
"standard" focal lengths or sometimes marked as film sizes. Since the
condenser setting is also affected by the distance from lens to condenser
the optimum setting depends a little on the amount of magnification of
image. That is determined by the uniformity of the illumination at the
printing surface. That can be measured with a printing exposure meter. In
all but specialized point source enlargers the uniformity of illumination
will be best with the lens stopped down a stop or two.
I hope this is not confusing, if any of it is ask and I will try to
clarify it.

I have an 8omm lens that mostly frustrates me (120 film). I need something
that will allow me to get the enlarger head up a little bit without going
to the ceiling. What do I want and is there a direction I can go to look
for a deal on it?
Thank you.
