Digital Photography
by John Rettie
PMA should be an Eye-Opener
If this magazine didn’t languish in your
in-tray for days before you picked it up you’re probably reading
this at about the same time that the photo industry is descending on Las
Vegas for the annual PMA show. Of course I’m writing this column
one month before the event so it can’t be a show report! Fortunately,
I have been privileged to get an advanced look at some of the new products
that will be unveiled, although I suspect there will be many more products
shown that I have no inkling about at this time.

is a substantially upgraded replacement for the D60. |
 |
While many, including myself, expected Nikon would
unveil an all-new digital SLR camera that does not seem to be happening
at this time. Instead Canon will wow the crowds with the EOS 10D, which
is a replacement for the D60 and will sell for only $1499 (estimated street
price). Considering the D60 was only launched less than a year ago and
has been in short supply the whole time it is a very pleasant surprise
that it’s been upgraded already and will sell for $700 less. What’s
perhaps even more important is that Canon says it has upped production
threefold so it should be in good supply fairly soon after PMA. This means
those “unfortunate” Canon users who couldn’t get a D60
in the past few months should now be able to obtain a better camera for
less money.
The 10D does not, as its name might suggest, have
a 10-megapixel chip. Instead it utilizes the same 6.3 megapixel CMOS chip
that was used in the D60. That’s not a bad thing as the results
obtained by this chip are well liked by most everyone who uses the camera.
Officially the D60 was not described as a professional camera body, mainly
due to its slower operation and less robust body. It also had a few shortcomings,
including slow autofocusing in poor light. Nonetheless it appealed to
many professionals who used it with great success.
The Canon EOS-10D uses an all-new body that is
made out of rigid magnesium alloy and is much the same size as the D60.
It features a high-speed wide-area 7-point autofocus system that should
be much more efficient. Canon claims that its latest DIGIC-based image
processor produces improved image quality over the D60. The camera will
also be faster in operation as it is capable of shooting at 3 fps up to
nine consecutive frames, in RAW, JPEG or simultaneous RAW+JPEG.
On the surface it would appear that the 10D will
be an ideal camera for all but a few professionals who need the really
high speed and rugged waterproof body provided with the EOS-1Ds. From
a cost point it’s a no-brainer as you’ll be able to buy five
10D cameras for the price of one 1Ds. Because of this Canon will probably
have to lower the price of the EOS-1Ds before too long.
With Nikon introducing specially designed DX lenses
for digital SLRs with small chips, it would seem natural for Canon to
do the same. However, Canon officials remain tight lipped when asked the
question.

| Fujifilm’s fourth generation Super CCD chip
takes a new route to producing better dynamic range. Fuji engineers
use this analogy with film to describe how the chip works. Silver
halide film is coated with crystals of various shapes—highly
sensitive grains with large surface areas that respond to small amounts
of light, and low sensitivity grains with small surface area that
responds to large amounts of light. The Super CCD SR achieves a similar
division of labor by mixing low-sensitivity and high-sensitivity pixels. |

Fuji is another company that is upping the ante
in quality with the announcement of its fourth generation Super CCD chip.
Fuji engineers quite rightly state that the number of pixels in an image
capture device is not the only criteria for producing a quality image.
To this end it is introducing two versions of the new chip.
The Super CCD HR (high resolution) chip is similar
in concept to previous generations but packs 6.63 million pixels onto
a tiny (7.3 x 5.4mm) chip. That’s a density equivalent to over 140
million pixels on a full size chip or 58 million pixels on a chip as found
in the Canon 10D!
The second new chip, called the Super CCD SR (Super
Dynamic Range) is the more intriguing one as it features a second set
of small pixels coupled to the regular ones. Fuji claims that the new
configuration produces approximately four times wider dynamic range than
the previous Super CCD. Although the chip has 6.7 million pixels, its
resolution is actually the same as a 3.3 megapixel chip as half of them
are the so-called S-pixels and the other half R-pixels. When information
captured by the two sets of chips is combined, the resulting image delivers
more detail in shadows and highlights.
Fuji likens the results to a negative film with
good tonal range. In examples shown by Fuji the quality of images captured
when overexposed was as good as a perfectly exposed image captured by
the previous generation Super CCD. It seems to be particularly good at
avoiding blown highlights.
The FinePix F700 is the first camera to be introduced
with this chip, but it is only a consumer point-and-shoot model. We’ll
obviously have to wait until later in the year to see the technology incorporated
in a new Fujifilm SLR camera body. If one does some simple math, it’s
easy to see that a larger chip size as used in the FinePix S2 Pro, could
easily have a resolution of 12 megapixels and each photo site would still
be larger than those in the upcoming consumer camera. It sure looks as
though Fuji will be able to deliver a professional level image capture
chip with good resolution and great dynamic range without resorting to
a full frame chip.
Many people thought that Olympus would unveil a
new SLR system at PMA after announcing its plans for a new standard at
Photokina last year. However, unless the company changed its mind right
before the show, it indicated to us that nothing would be shown publicly.
It seems then that Nikon has beaten Olympus to the punch by delivering
a new lens series tailored for digital photography. Perhaps Olympus should
adopt the Nikon bayonet F-mount as its “standard” instead
of developing a new incompatible mount?
With Kodak having delayed the introduction of the
14N camera with a full-frame chip and the high price Canon has placed
on its full-frame model, it would seem that we are still some years away
from having low priced (under $2000) full-frame camera bodies. If Nikon
and Olympus prove to be right in predicting the need for different optics
in order to garner the best quality from digital image capture devices
and Fuji’s new chip delivers greater dynamic range we may find that
35mm size chips will never be needed for the majority of professional
or high-end amateur camera bodies. Maybe full frame 35mm chips are not
the Holy Grail.
Apple’s Improving Outlook
Every month it seems there’s more good news about upgraded Mac computers
or new OS X software. January certainly was no exception. At the MacWorld
exhibition in San Francisco Apple introduced two new versions of the PowerBook.
Most impressive is a large version with a 17-inch screen. When I reviewed
the 15-inch PowerBook last year I said that I could see that model becoming
my main computer. The 17-inch model makes even more sense as a single
computer that can be used as a desktop unit and easily moved on location.
It’s not surprising to hear Apple expects laptop computers to represent
50% of its sales in the future.
Apple also introduced a smaller version of the
PowerBook with a 12-inch screen. It’s smaller size and lighter weight
makes it ideal for those who need to travel light and work on an airplane
but can’t afford first class tickets. Despite its small size it
still includes an integrated CD-R drive and a G4 processor. About the
only thing it lacks is a PC card slot. Perhaps Apple should have included
a Compact Flash slot so photographers could download images without needing
a cable or external card reader.
In my experience one of the few shortcomings of
a Mac compared to a PC has been slow Internet access. It always seemed
that pages took longer to load on a Mac than on a PC. No more. It turns
out it wasn’t the computer but the software. Apple has introduced
its own web browser called Safari that loads pages much faster than Internet
Explorer, which has been the default web browser for many years. I have
made Safari my main browser and even though it is a beta copy it works
well and is quite stable. There are some bells and whistles missing such
as automatic form filling and the option to not print the background of
a web page.
There’s still one area where the Mac is losing
ground and that is pure speed. Intel and AMD have continued to produce
faster and faster CPUs that are now reaching 3GHz. Motorola, makers of
the Power PC chips used in the Mac, have had trouble getting chips to
run faster than 1.2 GHz. Although the actual workflow on a Mac may still
be just as fast, there’s no question that when it comes to processing
images and running complex filters in Photoshop pure processing speed
still counts.
If one reads between the lines it would appear
a solution is at hand. A week after Macworld, IBM announced that it would
be working with AMD on future CPUs. At the end of last year there were
persistent rumors that Apple might switch to using AMD chips. IBM has,
of course, been a partner in the Power PC chip business with Motorola
and Apple since the beginning. I reckon that behind the scenes IBM, Apple
and AMD engineers are feverishly designing a new CPU for use in high-end
Macs that will run more than twice as fast as those we’re seeing
today. It’ll probably not happen until the end of the year but Apple
has to do something to speed up its computers, it’s about all that’s
wrong.

The Lexmark workgroup color laser printer
produces color prints that are more than
adequate for proofing photographs and for
general high quality color fliers. |

Lexmark Color Laser printer A week before I finished
this column I got a Lexmark C750n color laser printer in for review. Although
laser printers are the only printer worth considering for general business
use they have been a non-starter for photographers as the images they
produce have not been acceptable for photographic work. When I saw the
output from a Lexmark color laser at Comdex last year I was amazed at
the quality in a sample I was shown. Okay it was not strictly 100% photo
quality but it was 90%. I realized that a color laser printer could make
an ideal proof printer as well as be used for producing customized fliers
and general office work.
Now that I’ve played with this printer for
a few days I’m even more convinced that a color laser printer can
make sense for many professional photographers. It’s not yet a substitute
for a good dye-sub or inkjet printer for final output of photographic
images. However for quick proofs it has distinct advantages, such as lower
material costs and speed.
I was also under the mistaken impression that good
color laser printers were still expensive. They are not. Smaller printers
are now available for under $1000. However, the C750n costs $2399, but
that is $1000 lower than when it was introduced. It’s big, heavy
(105 lbs) and fast plus it’s a networked workgroup printer that
can survive a duty cycle of 60,000 pages per month. Considering these
specs it’s actually a reasonable price.
When I plugged it into my Ethernet network I was
amazed when my Mac recognized it immediately. In addition, I was able
to print from applications running under Mac OS X without loading any
drivers or performing any set up procedures. On the other hand, on my
PC I had to download a driver and manually enter network addresses to
get it to work.
Fortunately I have the printer on loan for several
weeks so I plan to run more tests and see just how good an output I can
achieve. I’ll report back on more of my findings in a future column.
In the meantime if you do a lot of proof printing or need to produce printed
color work take a look at color laser printer. They’ve come a long
way in the past couple of years.
Quick Book Review:
Digital
Image Making
The name of the book could be applicable to an artist or a photographer
but the book’s subtitle is A Complete Visual Guide for Photographers.
This is because it is a book written by Les Meehan, a British photographer,
who used to be a computer programmer. However it’s not a normal
book that shows how to do retouching or produce the best prints. It’s
aimed more at those how want to explore the production of alternative
images or create stylized photographs.
Essentially each pair of pages in the 128-page
book ($24.95, published by Amphoto Books) covers a technique on altering
or improving a picture. Many of the techniques described are useful for
a photographer who is new to digital image making, while others will appeal
to those who’ve learned the rudimentaries of Photoshop but want
to begin experimenting. Each section shows the end result and briefly
describes procedures with full color images and screen shots.
