Re: Center Filter--Do you need one?custom plaubel veriwide

[Simon Nathan <simonwide@xxxxxxxxxxxxx>]

dear yd- flash back in the memories
department. the late, great  frank rizzati thought up the camera and
i knew it goin' in that they were, as david letterman puts it, "one taco
short of employee of the month." this camera was hatched on the body
parts of an old plaubel roll film
camera. if memory serves me correctly  here behind my rock in east
orange, new jersey close to the shoprite supermarket. i
got mine in 1959 by picking it up in frankfort at plaubel. fall off didn't
matter to me because this was an assy-look 6x10cm negative. simmons omega
made a new negative carrier size. darkroom worker of that period often
burned in corners, upper at least, so here was a camera that took on 38mm
biogon (much, much-better,better) that gave a need for more enlargement
to match plaubel format. i owned and used both of these cameras. plaubel
had the leitz 21mm view finder engrave with brooks name. frank
rizzati died a happy man because
of this. me, because i wrote camera magazine stuff i knew that schneider
had a superb 53mm f. 4 yes eff-four, that covered 6x10cm wide open like
the way delta airlines once advertised when they were a lesser regional
carrier, to wit-"we cover dixie like the dew." this lens
covered at f.4. details on how this
was done of you'll leave a note just out my rock in east orange, new jersey.
i didn't discard the superwide, but i was joyous and joyful, whatever that
means.  for the record zeiss
had 45mm f.4.5 biogon at the time, covering 6x10cm wide open, but
shuck, who could afford it.

I have an odler Brooks Plaubel veriwide 100 with a 47mm Super angulon lens.

Well, this lens certainly wasn't made to be shot at f8!

I did a test ona roll of slow Velvia film to check the light fall-off.

Well, at f8, it was horrible.

At f11, a little better

At f22 a whole lot better, almsot not noticeable

At f32 I ws hard pressed to see anything. But f32 is not an ideal aperture.

Conclusion, if you use a cenetr filter and 100 ASA, you still need a tripod to
shoot at f11, because at two stops light falloff it's like shooting through a
f32 aperture.

Because 100 at f16 sunny 16-rule become 1/25 at f16 with filer in place.

If you want sharp pictures, you have to shoot at f16 or f22; I would not
recommend any biiger or smaller apertures.

Don't use over saturated film, liek velvia or Kodak's new VR Ektachrome.

Use regular Ekatchrome Sw or Fuji 100 prof. slide film (Astia)

And shoot f16 or f22 withotu a tropod. Small amount of light falloff, if any,
or if visible,  can be fixed by a computer
