Pixels to pictures
A digital primer to help you break the celluloid habit
By Marty McLennan
RARELY IN THE LAST decade have I
boarded a plane with less than three cameras
strung around my neck and a halfdozen
lenses and several boxes of
expensive film in my backpack. In my job
as a professional photographer, my trusted
35mm-film cameras have been a lifeline for
capturing high-quality images in unfamiliar
locations under impossible deadlines.
I had tested digital components over the
years, but I found the only means of achieving
photographs suitable for glossy travel
magazines and coffee-table books was with
analog cameras and slide film.
Or so I thought. A couple of years ago,
I invested in a digital camera for a twoweek
assignment, and the unexpected happened.
By lunch on the first day, I stopped
using film - cold turkey. Since then, I
have rarely bought a roll.
THE MIGHTY MICROCHIP
Quite simply, a microchip revolutionized
photography. Known as a charge coupled
device (CCD) or a complementary metaloxide
semiconductor (CMOS), this flat,
light-sensitive chip has replaced those cumbersome
and costly rolls of celluloid. The
CCD combines with a tiny in-camera computer
to offer luxuries only dreamt of in the
past. For instance, a digital camera allows
you to change the light sensitivity of your
"film" with the flick of a switch, easing the
transition from interior to exterior conditions.
At the processing end, the "development"
of images is instantaneous. You
preview results on the screen on the back
of the camera and can easily print your
own images.
When it comes to photo sensors, size
matters. Digital cameras typically range
between 3 and 10 megapixels, although
some models run as high as 16. The bigger
the chip, the greater the number of sensor
elements, or megapixels. Want to make
poster-sized prints? Pick up a 10-megapixel
camera. Oversized colour glossies? A
6-megapixel model will be more than
enough. Family portraits? A run-of-the-mill
3-megapixel will do. More megapixels offer better resolution, which translates into
larger and higher-quality reproductions.
In the digital age, where you can process
your own pictures at home, be sure your
camera doesn't exceed the capabilities of
your computer and printer. As you move
beyond 5 megapixels or if you plan to print
numerous high-quality images, you may
need to upgrade both.
