Photography 101

Through the eyes of a new photographer- by Kim de Araujo

When Ray and Debra offered to teach me more about the art of
photography, I was thrilled and jumped at the chance. Although, I have
had my Canon XTI for almost two years and have taken THOUSANDS of
photographs of my two young sons, I never thought I was completely up
to speed on everything my camera had to offer. I have very basic
knowledge of the art of photography and have been thirsty for knowledge.

When I arrived for my first lesson, the teaching studio was all set-up
and ready. I realized quickly that not only do Ray and Debra take
great photos; they have a wealth technical knowledge.

Our first lesson was short and sweet-just the basic elements of what
make up an “exposure”(for you professionals and seasoned amateurs out
there, I am sure it seems rather elementary, but bear with me).

Intensity (ISO)-is the film's rating, or how sensitive the film is to light.

In the digital world, ISO refers to the camera sensor.

200-400 is considered a day light exposure
400-800 is dusk or interior lighting
800 and above is for darkness


Time (the Tv setting on your digital SLR)-the burst of light (length
of time that your sensor is exposed to light) or shutter speed.
Shutter speeds are measured in seconds or fractions of seconds (1/125,
1/250, etc).

Aperture (the Av setting on your digital SLR) f/stop - the size of the
lens opening that lets the light into the camera. Aperture controls
the depth-of-field, which is what is in focus in the picture. Those
are expressed as f/2.8, f/5.6, etc. A wider aperture (low f/stop) will
narrow the depth-of-field giving a selective focus effect.

We put these “exposure” methods into practice by playing with shutter
speed and aperture to change the depth-of-field of our subject (which
was a line of bottles). It was amazing to see how little and how much
you can bring into focus just by moving these elements around on your
camera.

I have lots of practicing to do and more time I need to spend with my
canon’s manual before our next lesson. I can’t wait though. Thanks, Ray & Debra
