Provence Photographic Workshop Tour July 2-7, 2017



Built on the foothills of the Monts of Vaucluse, facing the Luberon, Gordes is one of the most well known hilltop villages in the region, and one of the most beautiful in France. Its houses and buildings of white stone root themselves into the sharp cliff of the mountain, its labyrinth of narrow cobblestone streets delights visitors and provide photographic opportunities.

The Luberon was one of my favorite shoots with W Stephen Johnson​ Gwyn Marschall Williams​ Jane Wilhelm​ Robert Parry​ Elizabeth Clasgens​ and Deborah Bondar bringing enthusiasm and laughter to the the hilltop villages and lavender fields.

The interaction of Aperture/F-Stop, shutter speed and ISO/ASA when Capturing your Images

1st Aperture/F-Stop, 2nd shutter speed and 3rd ISO/ASA

These 3 settings depend on one another and their interaction with light. A photograph is created by a chemical process where light is exposed to film, or a sensor in digital cameras. I always shoot on manual mode which gives me complete control on how I want to capture each image. I usually start my clients on Aperture Priority.



F/2.8 is wide open and allows the greatest amount of light to hit the Film or Sensor for your shortest possible exposure in a low light situation. F/2.8 will also give you the shallowest depth of field. When you have a shallow depth of field your main subject matter can stay in focus but your background will become a soft blur.

F/22 is stopped down and allows the least amount of light to hit the Film or Sensor. F/22 if used correctly will give you an infinite depth of field. Stopping down all the way requires a longer exposure which can cause motion blur

When you stop down two stops from F/2.8 to F/5.6   1/4th the amount of light will hit the Film or Sensor if your shutter speed and ISO/ASA remains the same.

You can either decrease your shutter speed by 400%
Or increase your ISO/ASA by 400%

F/2.8 at 1/120 sec with an ISO/ASA 100
F/5.6 at   1/30 sec with an ISO/ASA 100
F/5.6 at 1/120 sec with an ISO/ASA 400

If your exposure is too long you have a chance of motion blur
If your ISO/ASA is too high you will create noise
