Acme Enterprises: Digital Photography: The Fuji S2 Across The Digital Divide
Did you really get the shot?
(With digital, you know.)
|
Like most folks, I waited.
Several years ago, 1 megapixel point-n-shoot curiosities became
2 MP cameras that were actually usable. Early adopters like
Bill Groll
produced entire web sites with one, putting his Epson on auto
and shooting with gusto.
I waited.
The point-n-shoots were just that, while true digital SLR's were
ridiculously expensive -- $16,000 for Kodak's best. Film and a
scanner sufficed for me, buying time as technology pushed ahead.
About two years ago, Canon's D30 DSLR made digital photography
real, with images challenging 35mm film at a price many could
almost afford. No film or processing costs, no scanning, instant
feedback, and no grain -- the D30 was seductive, even at $3,500.
I waited.
Was 3 megapixels enough? Barely, and the next year or two would
increase the pixel count significantly. After nearly 20 years,
Moore's Law still holds -- the density of semiconductors doubles
every 18 months
Early in 2002, several manufacturers announced 6 megapixel
DSLR's and the lines began forming in cyberspace. User forums
filled with rumors and purloined test shots, as official
details and list prices trickled out -- 1/3 less $$$ than the
D30 being obsoleted.
Exhaustive reviews by
Digital Photography Review
made it clear -- 35mm film was in trouble. The new breed
of DSLR's could very nearly match film for resolution, but
the smooth grainless images sharpened better, producing
images most folks preferred.
I bought.

Just in time for 11+ megapixel DSLR's to be announced
at Photokina, of course. My spiffy $2,400 Fuji S2 is already
yesterday's news; I'll be lucky to eBay it for $1,000 in
18-24 months when I upgrade.
The good news is, film and processing savings paid for the
camera in a year. There's an almost giddy sense of freedom
that comes from shooting at no cost, which encourages folks
to shoot more, which may be the whole point of this
exercise.
So did I blow it? Should I have stayed on that fence another
year or two? It's a question some will ask forever, as quality
and features ramp up. So ask it another way:
When is enough enough?

|

Some exhaustive web reports
indicate the S2 is sharpest of the current 6MP DSLRs,
by a small margin. In side-by-side comparisons to 35mm
film scanned with my Nikon LS-2000 scanner, with optimal
sharpening applied to both, the S2 images look better.
Considerably better, though I'm really going to miss
Velvia's stunning color saturation...
For me, that's "enough". But it's not the whole story --
a story in progress.

When the box arrived, I just held the S2 for a while. It had
several times the complexity of the Nikon N80 on which it is
based, which has way more buttons than the Nikon F4 I used
for years. I'm a geek, so the downside of exponentially
increasing confusion wasn't lost on me.
Gingerly, I loaded both sets of batteries, aimed at a living
room wall, and fired. Amazing -- it worked. Right out of the
box, using factory defaults, without even a Compact Flash card,
a nicely balanced image popped up on the rear viewer.
I spent weeks photographing that wall, trying out ISO's and
external flash, climbing through custom features and controls
for resolution, color balance, viewer balance, under/over exposure,
and so on. Normally, I'm very methodical in testing the
capabalities of a new machine, but with no film costs and that
viewer, I fired off hundreds of frames trying every lunatic
variation I could think of.
Years of film shooting taught me to find a few settings that
actually work, and stick to them. The S2 had so many intriguing
options, it should have been terrifying. But it wasn't -- not
with instant feedback from a TFT viewer.
What it was, was fun...

See this motel way up in the Texas Panhandle? Just try
balancing neon, fill flash, and lightning with a film camera.
It's a photo I wouldn't have even considered, knowing Polaroids
or a half dozen sessions would be needed to get a decent
balance.

I was 5 miles down the road before it even occurred to me
the S2 might be able to handle this. I turned around, and with
instant feedback, it was not only easy but a hoot. That's the
real promise of digital -- photography becomes exciting again,
rich in new possibility.

Here's another experiment, shot in a dark neighborhood bar
with bounce flash at ISO 1600 (!) off a dark green (!!!)
ceiling. It took a few tries, but the S2 did most of the work,
producing color that required little tweaking and allowing me
to balance the minimal ambient light.
I've shot at Ginny's Little Longhorn before using film
and TTL flash, but I never attempted a ceiling bounce --
just too chancey. The S2 encouraged me try something
different, with an unexpected benefit:
Musicians stopped wincing, looking away, or closing their eyes
at just the wrong moment.

Bouncing seems to be a lot easier on performers than blasting
out retinas with direct flash in near-darkness. The S2
allowed me to capture this sensitive portrait of Dale Watson,
lost in his lyrics and the moment. That, or watching sports
on a TV above the refrigerator.
Ginny's is just that kind of bar...

After 18 months with this machine, here's a list of picks and
pans. It's a list in progress, so complaints are more likely
due to my ignorance than Fuji's engineering.
-
Briefly:
The S2 is very different from any film camera I've ever
used. Expect to change your shooting methodology to
accomodate it -- not vice versa.
That said, I'm not going back to film. The S2 produces
terrific images when its quirks are embraced, and design
bugs tend to get fixed over time. My bottom line is image
quality, which the S2 delivers better than any 6 megapixel
DSLR on the market, and considerably better than 35mm film.
-
Nikon N80:
The N80 has a decent feature set, but lacks 1/250th
flash sync or mirror lock-up. Multiple web comments
suggest it has enough mirror/shutter vibration to
make it a lousy candidate for crisp telephoto shots.
My own experience confirms that, despite using a
hefty tripod. A $2,000 camera should offer
mirror-lockup, which suggests Fuji needs to start
building its own camera bodies. So should Kodak,
offering more pixels but the same amateurish Nikon
body.
-
Digital Workflow
With no film costs and no scanning time, I'm shooting 3-4X
my normal number of frames. After shooting 100 S2 frames,
it takes only minutes to transfer the images to a computer
and do a rough evaluation. With film-based images, the
process of "loupe/cut/scan/examine" takes me about 5 minutes
per image.
A purely digital workflow like the S2 is a
huge time saver!!!
-
Image Control:
S2 images tend to be a little warm, much like putting an
81B warming filter over the lens. That works well for
flesh tones, and even some landscapers prefer the look,
but I find it dulls a blue sky. Largely correctible
in Photoshop, of course...
The S2 allows the user to roughly set image density and
contrast via the "Color" and "Tone" options, but color
balance is another matter. For landscape work, I find
Fuji's standard settings work best.
Images can also be saved in RAW mode for maximum
post-processing correction, but at the expense of storage
size and speed. Expect to add several minutes to
your normal touch-up time on a PC, since each RAW image
must first be converted by a dedicated program. Personally,
I don't find sufficient advantage to justify using RAW mode
instead of Fuji's 12MP jpeg mode.
A simpler approach might be a custom white balance, aiming
at a lightly colored sheet of paper instead of pure white.
Mentioned briefly in the user's manual, Fuji might
facillitate this technique with a dozen tinted 4x6 sheets --
the equivalent of colored lens filters without the cost.
-
Image Sharpness:
Many folks have initially been surprised at how "unsharp"
an S2 image is, right out of the camera with no post-processing.
Including me, so I ran some tests.
These images were shot at 6 megapixels, ISO 100, using a recently
realigned Nikon 28-105mm at 50mm (effectively 80mm on the S2).
The images below have been "auto-leveled" and judiciously sharpened
in PhotoShop, and are shown at 100% (1 S2 pixel = 1 screen pixel).
I tried a wide range of shutter speeds, but these are typical.
Hand-held, 1/250th
|
Monopod, 1/250th
|
Tripod, 1/250th
|
It's hard to judge the monpod-vs-tripod tests without viewing
at 200%, but the tripod was always the winner. The clear loser
was the hand-held shot, even at a shutter speed much faster
than that recommended by the old "Daylight Rule" -- 1/focal length.
Surprised, I reshot the scene on film, using the same
lens at 80mm to match the "effective focal length" of the
S2 tests. As expected after several decades exposing film,
the tripod and hand-held images were very similar at 1/250th.

So digital requires a tripod when film doesn't? This
is progress?!
Take a deep breath, and look at those shots again.
Notice that the hand-held S2 image is about equal to the
hand-held and tripod shots on film, while the S2 tripod
shot is clearly superior.
To me, this suggests the S2 is capable of better resolution
than Reala scanned on my Nikon LS-2000 film scanner. Both
film shots are similar because Reala just can't show the
addtional detail possible with a tripod.
The S2 can...
Cool -- those "soft images" I worried about were probably at
least as sharp as the same shot done with film. Still, to
really do the S2 justice, use a sturdy tripod. An old adage,
but more relevant than ever...
-
High ISO settings:
The S2 produces very usable images at ISO 800 and
even 1600 if a little grain is acceptable, but TTL
flash seems most reliable at lower ISO's. Fuji
specifies ISO 400 as a maximum.
Reaction time seems to be the culprit. At wide apertures
and moderate distances, flash times become so short that
the S2 can't turn most flashes off quickly enough.
Even at ISO 400, an f-stop of 5.6 or 8.0 may be required
to avoid overexposure. That may prove disappointing
to folks who paid handsomely for an 85mm f1.4,
hoping the S2 would provide fill flash to balance
but not overwhelm weak ambient light.
The solution is to add "neutral density" to the strobe
head and make the flash fire longer, giving the S2 more time
to quench the strobe. I've gotten some arguments about
this approach, but adding some ND acetate or even a
Stofen or Lumiquest softbox to the strobe head can often
save the shot.
Despite Fuji's admonition to stick to ISO 400, instant feedback
and a few test shots can make flash useful at higher ISO's.
That ISO 1600 shot of Dale Watson above convinced me, and
my recent
Billy Bacon page
was shot entirely at ISO 800 and TTL, with 2 stops of ND
material over the strobe.
Why all this emphasis on high ISO shots, where grain becomes
objectionable? Because grain can be tamed, using programs
like
Neat Image.
-
Batteries:
The S2 seems conflicted by its dual battery system. The
base Nikon N80 uses CR-123A batteries to power metering, AF,
and that cute pop-up flash. Fuji added a lot of electronics
and powers it all with a battery tray holding 4 AA's.
The net effect is erratic behavior which can be crippling
during a fast-moving shoot. The S2 just stops cold for
no apparent reason, sometimes even after CR-123A's and AA's
were recently installed. This is a real problem, and
Fuji really needs to fix it.
Fortunately (sic), the camera will operate on just AA's,
which often seems to calm the S2 down. That pop-up strobe
won't work without CR-123A's, but otherwise the camera seems
to function reliably.
Currently, I'm using PowerEx 2200 NiMH batteries and
CR-123A's. The S2's electrical problems seem largely
solved by a steady voltage supply, and NiMH batteries
do that better than alkalines. Since switching to
this setup, I haven't had a problem.
Need a source for cheap CR-123A's? Try
Botach Tactical
, where Toshiba CR-123A's go for about $1 each.
Hot Tip:
If your S2 quits and seems dead to the world, take out
both sets of batteries and install only fresh AA's --
no CR-123A's. Let the S2 sit a few minutes before
turning it back on. No guarantees, but this may save
you a trip to a Fuji repair center...
-
User Interface:
Superb... almost.
The S2 features a set of buttons and a small display
for commonly adjusted settings, and it's back-lighted.
Changing white balance or image resolution takes seconds,
and it can all be locked to avoid resetings by a nose or
errant finger. Brilliant!
But I was baffled the first time a CompactFlash card
filled and the S2 stopped working. The TFT display
indicated some current settings but nothing so helpful
as "Storage Full". Hint to Fuji-san: that display is a
swell place for user-friendly messages in large fonts.
Also puzzling was the steady "ERR" message that shows
up occasionally in the LCD panel on top. Resorting to
the manual alerted me to depleted batteries, but "BAT"
would be more helpful. Probably a Nikonism, not Fuji's
fault, but it should be addressed.
-
TFT Viewer:
As with every other digital camera, the TFT viewer on
the back is nearly useless in full daylight. I tried
one of those silly "chimney" add-ons and wasn't impressed.
My next "solution" may be a dark cloth, borrowed from
earlier flirtations with a 4x5 field camera.
Even in dim light, the viewer isn't a perfect indicator.
Changing your angle of view just a few degrees changes
the apparent density of the image, making exposure
judgements difficult.
Happily, the S2 histogram can roughly indicate density,
though I'd also like to see problem areas highlighted
directly on the TFT image, like most image editors already
do. It'd be nice to know if that histogram spike indicates
a blown-out cloud, or if you've just lost important detail
in a bridal gown.
However, the proper place for a TFT display isn't on the
back but in the viewfinder, shielded from external light
and prying eyes. A fast efficient 1 megapixel EVF (electronic
viewfinder) should rival a traditional SLR viewfinder, and
opens up a lot of design possibilities.
First, the mirror can be eliminated, since the EVF would
get its signal directly from the sensor. With the mirror
gone, lenses can be moved closer to the sensor. Sharper
and more compact lenses could be designed -- one reason
mirrorless rangefinders like the Contax G2 and the Leica
outperform 35mm cameras.
Heck, the sensor itself can be moved, simulating the
rear standard motion of a 4x5 view camera. Every lens
gains some "perspective control" capability, though
most current 35mm lenses don't have a sufficiently
wide image circle to much movement of the sensor.
Yet another reason for new lens designs...
Realtime image previews also become possible -- a feature
already offered by even the lowliest digicam. With a mirror
in the mix, a photograph must be taken before it can be
examined -- archaic in a digital camera.
Another potential bonus: dial in the desired image
format (35mm, 645, square, TV, panoramic) and see
only that in the viewfinder and in the final image.
I hate trying to make an image framed for 4x6 fit
into a 5x7 frame -- something always gets lopped
off. A maskable viewfinder would help.
An all-electronic viewfinder, no mirror, a new line of
sharp short-mount lenses -- it's major design leap, to be
sure. But somebody will do it -- the advantages are
compelling, and the competition is relentless.
