I think it's important to repeat what someone else wrote earlier, and to
make another point.

1) The "excellent" pictures you're viewing are in greatly-reduced-
resolution digital representations of the real 4x5 transparencies.

2) The excellence comes from exquisitely skilled lighting, composition,
and framing, along with appropriate selection of subjects. Anybody with
a 10Mp camera can produce pictures with that _clarity_, but most wouldn't
likely be able to convey the _message_ with that clarity.

Most digicams don't work well with high numerical f stops. Thus, properly lighted, a 4x5
camera will have greater depth of field than a digicam. It was one of the first things I
learned when I went with compact digital cameras.


Wes, as a guy with two 4x5 cameras and 15 magazine covers behind me,
you'll have one hell of a time getting a lot of depth of field with a
4x5. When I've had to, it's been f/64 and use the swings and tilts.
I've also used an 8x10 Calumet for some trade-show Translites for
Casio. That sucker really shows you how depth of field disappears with
large sheet film.

When someone talks about "depth" in photography, I think of the things
that give the impression of actual, physical depth. Others have
pointed to expert lighting, and that's a big part of it. Kodachrome
also has (had) a slight inherent edge effect, which gives the
impression of more depth. And people like me, who made his living for
a while silver-masking Kodachrome slides, can tell you about another
edge effect. Or you can use Unsharp Masking in Photoshop and get
almost the same thing.

Anyway, it's there. But it's probably all lost in conversion to a
moderate-res digital copy for the Web. You'd have to blow it up and
look really close.

Some day, I'd like to own a DSLR with a 24x36 mm sensor, then what I learned on will be
relevant again.

Just my opinion,

Yeah... I had a Press Graffix 4x5 with a film-pack back.

It could do some sweet portrait work, though!

You have more patience than I do. I used my Speed Graphic for some
in-the-field shots for American Machinist, but I shot covers with a
Calumet 4x5 monorail. They were mostly tricky machine shots -- often
multiple exposures -- which the shutters excelled at. And I did a lot
of tabletop work for McGraw-Hill book company, freelance, before the
M-H publications company hired me.

But silver-masking actually paid better. It was a pretty obscure
darkroom skill, and I had work coming out my ears. Again, that was
when I was first freelancing.

When I ended that period, my wife says my eyes had shrunk to little
dots from spending full days in the darkroom. d8-)

Dunno where the killfile resident gets the idea that digital cameras
don't work well at high f stops. My 30d works very nicely at any f stop
that any of my lenses can achieve. On the other hand, the performance
of the lenses is compromised by diffraction at small apertures, but that
affects any type of sensor.

But if you want a mighty ****load of depth of field, go for one of the
little point-and-shoots.

My cell phone does well at that, too. d8-)

I sent Wes a photo I shot with my crappy cell phone (a dumb phone, not
a smart one) a couple of years ago. It has even sharpness from the
right pectoral fin of the bluefish all the way to Staten Island.

It must have a teeny little sensor but a little unsharp masking makes
the fish pop pretty well.

Check out the photo captioned (about number 26 down the page):
-----------------------------------------------------------------------------------------
"October 1942. "Thousands of North American Aviation employees at
Inglewood, California, look skyward as the bomber and fighter planes
they helped build perform overhead during a lunch period air show.
This plant produces the battle-tested B-25 'Billy Mitchell' bomber,
used in General Doolittle's raid on Tokyo, and the P-51 'Mustang'
fighter plane, which was first brought into prominence by the British
raid on Dieppe."
----------------------------------------------------------------------------------------

Lots of black bags under those folks' eyes. They look like they are
busting ass working long hours on not much sleep. Factory probably
going non-stop 24/7.

Even in 1942, they were probably smart enough to not do the show
directly above all those workers they needed... Many do seem to be
looking up at a low angle, but then again, most of the other pictures
were clearly "posed" for so the photographer may have just said "hey,
everyone look over there!"

That was worth the time I spent viewing it. From a time when exposing a 4x5 sheet of
color film was expensive enough to warrant spending the time to get composition and
lighting correct.
