Below is the abstract of today’s Veteran’s Photography Workshop lesson plan. The assignment is at the bottom.
Two types of light meters:
Reflective: Measure how much light bounces off a subject. Most cameras have this type of meter and it calculates the scene and the amount of light to produce a medium grey or average scene.
Incident: Measures how much light is actually falling on the subject. These are typically hand-held devices and are very accurate.
Rule of thumb metering: f16=bright sunshine, f11=partly sunny, f8=hazy overcast, f5.6=overcast
Cameras have three basic controls to control exposure for light and shadow
Sensor/film speed: The ISO setting on your camera is for adjusting the sensitivity of the light meter. Low light generally requires a higher sensitivity (high ISO) and bright days generally require lower. The subject matter of your scene will ultimately determine what settings you need to use.
Shutter (Tv): The mechanism that determines how long light is exposed to the sensor/film. Controls motion.
Aperture (Av): The variable opening of the lens that admits light, measured in f-stops. Controls depth of field.
All of these controls impact the amount of light reaching the sensor/film—proper exposure.
Assignment
To photographically tell an action story, motion is key. Produce two images, properly exposed, showing motion: 1) an image showing sharp subject and blurred background and 2) an image with sharp background and the subject in motion with some blur—make sure the subject is recognizable.
