This is true presuming that the ray trace from the lens to sensor  
does not change dramatically such that the edge/corner areas on the  
larger sensor are too oblique, or if the sensor has been designed to  
be more tolerant of accepting light at oblique angles.


Ideally, a larger lens mount and lenses designed for a more  
telecentric ray trace should be used. Less ideally, but still an  
improvement, would be reformulated lenses with the same principle in  
mind.


The secondary question is whether the larger sensor technology is

Bob, I look at pixels more as grain in film. All else

greater resolution than the same shot using 200 Gold.
Regardless of format, I assume there would be no limit

Pixel count, fill factor and sensor size (and other factors as well) all
come into play. An 11mp full-frame sensor might have larger pixels than
a 6mp APS-C sensor, so it could be both lower in noise *and* higher in
resolution. Improvement in technology also comes into play because it's
always advancing: This year's sensors are lower in noise than those from
two years ago.

For sensors of the same pixel count. "More tightly packed" is another
way of saying "smaller", and therefore noisier, pixels.

>Thus, according to the writer, assuming the same pixel count, 
>the smaller sensor would capture and reveal more detail.
>Why do I doubt the assumption?

Because, although it may theoretically capture more detail per unit
area, the sensor is smaller and the image will therefore require more
magnification for a print of the same size as one made with a larger
sensor, therefore losing resolution in the final image. And, as the
image is magnified for the final image, so will be noise, which is
already higher with smaller sensor pixels.

It's remarkably similar to film: The less magnification you have to do
to your capture when making the final print, the better off you are.

Re: The Nature of Film's Final Throws

2005-08-26 Thread Bob Blakely
There will always be a niche market for film, even 35mm. Digital will 
supplant it for most real applications, most importantly in the consumer 
market where the dollars, euros, pounds, yen, etc. are, but film still 
offers some image advantages (or at least claimed advantages), and 
aficionados will still provide some market, enough for perhaps two or so 
small outfits to produce it. The intelligence agencies still use it for best 
detail and (what's the word?) acuity and will continue to use it for non 
real time airborne reconnaissance, so someone will continue making that. 
Slitting it  to 35mm and perforating it is a small thing, and it can then be 
sold to those few consumers who still want it. Astronomers will still demand 
it for some applications, though the format will be larger, still, it starts 
out as rolls that can be slit. Why 35mm? Well, in my opinion it provides the 
best compromise between versatility (as a function of size) and quality (as 
a function of image area). FYI, while I'm sure that many will not agree, 
this is the same reason I would prefer a 24x36mm sensor for a 35mm sized 
camera. As it is with film, so it is with sensors - the larger the format, 
the greater quality potential.

How much longer will starving film cameras demand 35mm
color pos/neg films be produced? What level of
production and availability would qualify as "in
production"?
What's the likelihood of film's resuscitation through
some manner of structural breakthrough?

I have to pass along one more endearing film
experience;
My now 41 year old daughter who, when asked to suggest
some High School graduation gifts, immediately named,
"a good camera".
She received a Pentax K1000 w/M-50mm f/1.7 (I
believe)and has since added short and medium Pentax
zooms.
Must mention that her K1000, also, got stolen. I
replaced it while remembering my experience.
Some while back, while tinkering with our cameras, she
mentioned that she had "always liked the smell of
film". At that moment, we became even closer.

David,
Thanks for the retro trip.
My memories (too far back to totally relate here)
begin with  sitting by my father in his basement
"darkroom" , nostrils full of the smell of chemistry,
and being amazed each time an image developed in the
tray.
First camera, Baby Brownie in about 1942. Took it to
school to show off and (Mom was right) it got stolen.
Crushing day.
Still have the first picture taken.

As fewer shooters are using film, the market,
obviously, becomes unable to absorb current production
volume. 
Reduced production levels, then re-balances with
demand. A supply v demand competition might satisfy
film users for some time. It's that "time" value I and
the owners of millions of film cameras, are wonderin'
about.
At my age, no way will I see the end of film.

I don't know if film will actually die.  Someone somewhere will continue to
manufacture film stock if there is any demand at all.  It's interesting 
but some
discontinued film types have even made something of a comeback.  
Expensive but
available.  A few years ago you couldn't get 620 or 828 sized film.  Now 
both are
available if ordered on the Internet.  There will probably always be 
enthusiasts who want to
shoot b&w film.  At least enough world wide to create enough demand for 
one or two maybe
even more manufacturers.  Maybe not Kodak, or Fuji, but someone will be 
there to satisfy
the demand.
