Walking into a camera
store, many a photographer automatically assumes that if a camera
has more megapixels, it takes a better picture and, therefore, is
the better buy. Such an assumption doesn’t reveal the whole
truth, however. The reality is that although higher megapixels promise
bigger prints, pixel count doesn’t tell a photographer much
about shutter lag, battery consumption or color accuracy. And as
photographers go out and use their cameras, they soon discover that
their high-resolution camera isn’t always translating into
equally high performance.
Today, cameras are more than just the sum of their megapixels. With
digital cameras offering resolutions of up to 8 megapixels for less
than $1,000, the ability for photographers to produce quality enlargements
is available to everyone, not just the pros. As a result, camera
manufacturers are competing on a much broader battlefield, each
trying to distinguish themselves.
To understand what’s happening, we spoke to several representatives
from the leading manufacturers for their insight into where digital
technology is now and where it’s going.
About Those Megapixels
Less than a decade ago, a 2-megapixel digital SLR cost more than
$40,000. Now, digital SLRs with three times the resolution are available
for less than $1,000. That’s a remarkable change in less than
10 years. The top-of-the-line cameras now offer resolutions of 12,
16 and even 22 megapixels (with the Mamiya ZD). Yet as these higher-resolution
cameras become available, a photographer wonders how high will it
go and how many megapixels does one actually need?
“There will be technology improvements that will increase
resolution,” says John Knaur, senior marketing manager for
digital SLRs for Olympus Imaging America. “But we’ll
also meet a point of diminishing returns, the key point being how
much resolution do you actually need to create a 4x6 print or an
8x10 print? In reality, I think we’ve gotten pretty close
to that point with most people.”
Resolution is related primarily to the intended print size and not
exclusively to overall image quality. Four- to 6-megapixel cameras
provide more than adequate resolution to create excellent-quality
8x10 prints. For photographers who prefer making enlargements up
to 16x20, digital cameras boasting up to 8 megapixels are both available
and affordable. While resolution is important, consumers and manufacturers
are focusing on the other attributes that lead to successful photography.
“Resolution will continue to climb as manufacturers innovate,
but I have a feeling that the industry is starting to pay attention
to other things,” comments Steve Heiner, Nikon’s general
manager for digital SLR systems and Nikkor lenses. “For example,
on the professional end of the business, there are a myriad of cameras
that provide photographers with the resolution necessary to do the
things that they need to do. Many can argue that they can do things
now with digital that they couldn’t do with film.”
As photographers’ experiences with digital cameras have grown,
so has their awareness of what ultimately makes a difference in
a camera.
“Today’s consumers are becoming second- and third- rather
than first-time digital camera buyers,” notes Andy LaGuardia,
senior manager of corporate communications for Fujifilm. “When
they bought their first digital camera, they wanted as many megapixels
as they could get or afford. Now they’re coming to the camera
store with experience that tells them to look into battery consumption,
shutter lag and other performance issues.”
There’s a distinguishing line to be made between consumer
and professional cameras, however. Although today’s compact
and affordable digital SLRs offer more than ample resolutions for
most photographers, professional cameras will likely still see further
increases in resolution.
“In the digital SLR category, there’s room at the top
of the market for professional cameras to exceed the 16.7-megapixel
benchmark established by the Canon EOS-1Ds Mark II,” says
Chuck Westfall, Canon USA’s director of technical marketing.
“Speaking strictly about image sensors, there are no significant
limits on sensor physical dimensions using CMOS technology, but
the bulk of the market will continue to be in the 35mm size of the
24x36mm category and smaller because of other factors like lens
selection and conventional 35mm-based SLR camera body design.”
Moving Beyond The Sensor
Issues such as signal noise, color accuracy, shutter lag and image
processing are increasingly becoming key qualities to evaluate when
considering any digital camera.
“I think now where you’ll see the technology pushes
are in the ‘individual technologies’ that happen behind
the scene,” says Nikon’s Heiner. “You’re
going to start to see new noise-reduction algorithms employed and
other things that improve image quality.”
Along with such features, the ease with which photographers can
create good-quality images and see them to the final print has grown
in desirability. This is especially the case with understanding
the importance of in-camera image processing.
“Image processing plays a big role,” says Fujifilm’s
LaGuardia. “Someone said that image processing is the ‘secret
sauce’ for every manufacturer. It’s that image processing
that helps produce the color and the effects that make each digital
camera, each manufacturer unique to itself.”
Such processing allows the camera to take full advantage of the
data recorded by the image sensor, as in the example given by LaGuardia
of the Fujifilm FinePix S3 Pro, which utilizes its sensor’s
expanded dynamic range to simulate the color and tones of negative
and slide films.
Whether photographers want the camera to handle everything automatically
or desire to maintain complete control, today’s cameras are
designed to provide the best of both worlds.
“Photographers who don’t want to spend a lot of time
in front of the computer influenced one of the design concepts behind
the Nikon D70,” explains Heiner. “The D70 produces in-camera
the kind of colors people expect in their photographs. In the case
of the consumer camera, we want it to be as good as it can possibly
be so the consumer can go directly to the printer and get the best
results.
“If it’s a professional, we want to give them the most
versatility possible by offering them the NEF file [Nikon’s
version of RAW] that gives them all sorts of image-processing options,
but maintains the integrity of the original file.”
The concept behind many of today’s digital cameras, particularly
SLRs, is to make a camera that can automatically produce images
with excellent color, tonality and exposure that lead to an efficient
and speedy workflow. They’re also being designed with controls
and features, including RAW, that offer photographers total control.
“It really depends on the photographer and the type of imaging
that’s being done,” says Canon’s Westfall, explaining
the choice between RAW and JPEG. “For example, photojournalism
and sports photography is heavily based on a JPEG workflow for speed,
whereas commercial studio photography relies on RAW files for quality.”
“The workflow is constantly changing” says Olympus’
Knaur. “It was once simply about downloading. Now RAW is like
developing film and prints during the old darkroom days. RAW allows
you to tweak your digital negative to a much higher level for a
much greater use. It has made it all much faster and more reliable
to produce a higher percentage of better pictures.”
Creating Distinctions
Understanding color and exposure always has been critical, but it’s
now even more crucial for digital image creation. Today’s
cameras can produce great results automatically, but they’re
not foolproof. To create quality digital files, photographers have
to understand what’s possible with their cameras.
“The current generation of EOS digital SLRs offers a great
range of in-camera color adjustments for photographers,” says
Westfall. “The cameras include custom tone curves, multiple
white-balance settings, dual-axis white-balance compensation, white-balance
bracketing and multiple color spaces. As we move forward, we’ll
continue to improve our products based on customer feedback and
advancements in technology.”
One must consider color space, believes Knaur, who explains that
the complete digital workflow from camera to printer to final print
involves photographers having a greater understanding of computers
and, specifically, a color-managed workflow. As a result, camera
manufacturers have had to become software engineers, too. Says Knaur,
“It creates more of a challenge because we have to build more
into the camera. Adobe Photoshop provides us the control that was
once only available at your corner film lab. Now we have the ability
to help photographers not only take their pictures, but edit, enhance
and output their photographs.”
While requiring new skills, this development has given photographers
greater control over their creativity.
“One of the most important aspects of digital photography
is that it completes the entire creative circle,” offers Heiner.
“Before, if you imagined an image in your mind, you had to
hand that film to somebody else. With digital photography and understanding
all the steps in the process, you now can imagine an image in your
mind and carry it all the way through to matting it, framing it
and hanging it on your wall.”
The fierce competition of the megapixel war has inspired innovation.
Along with that progress, much of what consumers have wanted—larger
LCD screens, reduced shutter lag, easier-to-use software—has
found its way into each new generation of cameras.
