Reciprocity Is a photographic theory that states: that they are many different combinations of balanced exposures.

Reciprocity is Equal Balance Exposures We refer to these equal balanced exposures as > Equivalents <

“Review”

Equivalents Example: Balanced Exposure 1/125 1/500 1/250 1/125 1/60 1/30

All of the above shutter speed and f/stop combinations would be equivalent exposures and would result in balanced exposures for the subject being photographed.

Equivalents Quiz: 1/1000 1/___ 1/250 1/___ 1/60

Equivalents Answers: 1/1000 1/500 1/250 1/125 1/60

Why Do We Practice Reciprocity ?

Equivalents Which Shooting Mode Do You Use? Manual (gives you full control but do you need it?) Shutter Priority (TV) Aperture Priority (AV)

Equivalents Manual Mode: allows you to control both “Movement” and “Depth of Field” freely without having to switch shooting modes.

Equivalents Aperture Priority Mode: allows you to control “Depth of Field” by choosing the f/stop you wish to shoot at and the camera will choose the correct shutter speed to give you a balanced exposure.

Equivalents Shutter Priority Mode: allows you to control “Movement” by choosing the shutter speed you wish to shoot at and the camera will choose the correct f/stop to give you a balanced exposure.

Equivalents Both Shutter Priority & Aperture Priority Shooting Modes make it easier to do equivalents so we can take advantage of the creative controls that our cameras allow us to do!
