There's a new page up at http://chasfs.com/fireman.py which contains a
photo that I took the other day.  I've saved it with an old version of
Photoshop so it should be a bit of a challenge to tell how it was made.
The original sized image is available as a link from that page, but
its 13MB, so download at your own risk.  Can you identify the camera,
lens, etc. that were used to make this image? There are clues, but I
promise you - you'll be very surprised by the answers!
Peace,

Looks like a high-res scan from 35mm slide film.

Any thoughts on film, scanner, or lens?

Provia 100F (from the slight blue cast in the sky/background), Minolta 5400
(from the file size), towards, but not at, the long end of a 28-75mm zoom.

Am I way off?

Yes, you are way off.   So far the only thing that you've correctly
identified is that it is slide film.

And I was about to doubt that, since there's some colored speckles in some
of the lighter tones<g>.

Those speckles are significant.  More clues about the film are
available in my prior postings to this newsgroup.

What's mysterious? That it's poorly focused? Accidental composition?

I take it back.  It's not that badly focused.

Thank you, j.  I did as well as I could with no AF available.

Looks like a 4000 ppi scan from a 645 camera.
No shadow detail so it looks a lot like slide film of some kind.

Scott
chasfs - 02 Dec 2006 03:51 GMT
Hi Scott,

You have correctly identified the precision of the scan and that it is
slide film.  It is not a 645 camera.  Care to guess which slide film,
camera, lens, shutter speed, etc.?

It does not match any film I know but is not too far from 128 film, but
then that has not been used for more then 60 years so that does not
seem very likely.

It could be some camera using 70mm film stock, but then I don't know of
any still camera that used that fromat.

The Height is right for 120 or 220 film so I am guessing that is the
most likely, but it is even too narrow for 645.

Not knowing the format I can't even begain to guess the camera.

I would guess the lens to be between 50 and 80mm and shot at around
f/5.6 to f/8, shutter speed of at least 1/250 I would say, but most of
that is a wild a.s guess.

chasfs - 02 Dec 2006 13:25 GMT
Hi Scott,

Your reasoning is sound, and it is 120 format film. This is the medium
format newsgroup, after all!  When I took this photo, someone stepped
out in front of me just as I pressed the shutter release, so I cropped
them out. I apologize for not stating this earlier.  That's the only
manipulation made, other than output to JPG for a smaller downloadable
image.  More clues about equipment are available in my previous
postings to this newsgroup and on chasfs.com.

Well that makes the film pretty easy Provia 400F push to ISO 1600.
Says my guess for shutter speed is likely on the rather low side and we
are more likely looking at 1/1000 sec.
For a camera how about a SMC Pentax 67 with a 55mm lens?

Scott
chasfs - 04 Dec 2006 17:52 GMT
Bingo on the film and camera!
Amazing for ASA 1600, I think.

Correct camera!  5 stops to slow for the film. Much longer lens (and
heavier) lens.
RolandRB - 03 Dec 2006 05:56 GMT
I guess you were hoping to get the reflection of the fire truck in the
shop window to the right when somebody walked by and spoiled the shot
and for that sort of shot then a telephoto lens is less intrusive so I
guess you were using a Pentax 67 with a Pentax 165mm lens. There is a
lot of detail on the shot but it looks grainy to me so I'd guess at a
200 speed Ektachrome film.

Just guessing.

Good guesses!  Shot at a much higher speed, and a longer lens, hand
held.

I'm guessing a longish lens (about 135 TO 150mm) on a 645 of some kind.
 Shaddows and grain suggest slide film, such as Kodak E100.

The file print res was set at 4000 (in the 13 MB file) which is a
characteristic of the Nikon  8000 / 9000 scan s/w.

Guess even longer on the lens, bigger on the camera and 4 stops faster
on the film.
My scanner is similar, but doesn't have digital ICE.

Thank you all for playing along.  I've updated
http://chasfs.com/fireman.py with the details about how the mystery
photo was made. My conclusion - Fuji Provia 400F pushed to ASA 1600
gives amazing results.
Peace,
