Photography Workshop

April 16, 2011 - Southeast Louisiana National Wildlife Refuge Complex

Light is painted on the retina of the eye, film or the sensor and then on the monitor, paper or screen
The painting is controlled by the (natural) quantity of light (as modified by you)
And the (natural) quality of light (as modified by you)

ISO and ISO equivalents (film or digital sensor sensitivity) …for film this is ISO/ASA 25 to 800 (or more) and for digital cameras from ISO 100 to 1600 (or more…)
Shutter speed

- Generally, subject and camera movement is your enemy...

- The ability to stop movement increases as the shutter speed increases

- The ability to create artistic blurs and the sense of movement can (with skill) increase with slower shutter speed
Aperture (the size of the opening in the lens) expressed as f stops and the implications to depth of field and sharpness

- f/1.4 to f/32

- “Depth of Field” (depth of focus) increases as the aperture gets smaller and the f number gets larger for any lens.

- The longer the focal length of the lens, the narrower the inherent/available depth of field
And in the case of digital photography, "white balance or color balance."
How about some more photos that (hopefully) highlight the mastery of the technical variables?
