About how deciding aperture is preferential in photography or shutter actor depends on first of different photography condition and different subject matter film. Aperture is preferential with shutter preferential it is the issue that involves photography exposure, it is the different pattern of automatic exposure.
Contemporary camera has pattern of 4 kinds of exposure commonly, it is respectively:
Exposure of P/ order pattern
A/AV aperture is preferential (aperture predetermination)
S/TV shutter is preferential (shutter predetermination)
M/ hand alters exposure
(before 3 kinds are automatic exposure mode, the 4th kind is the hand uses exposure pattern)
Aperture is preferential: Call aperture prerequisite again, in the automatic exposure of camera, regard dominant and set as the value with aperture, match the exposure pattern of shutter speed automatically. Should consider depth of field commonly (distinct range) wait for an element, light is used to encircle preferential mode when needing to control shutter rate. It is commonly in photography of a lot of scene, figure photography use aperture preferential.
Shutter is preferential: Call shutter prerequisite again, the main effect of shutter is the false or true that controls aspect of apply the brake, general use shutter is preferential when should needing to consider dynamic and video definition. In a lot of sports photography, dynamic object films in use shutter preferential.
Specific should use how old, want a basis to film circumstance and subject matter will decide actually:
Commonly used aperture is preferential, the aperture that films Xiaojing can use F2.8 dark painting of flowers and plants in traditional Chinese style, figure for instance is preferential, the small aperture that should film F16 or F22 can be used when the natural scene outdoor will acquire bigger depth of field.
Commonly used shutter is preferential, should film match of a few sports, the shutter rate that 1/250 second above uses more when high speed mobile is preferential, what use 5-10 ″ more when filming car light pulls off the rails mark is slow fast shutter is preferential. The shutter that films high speed uses 1/2000 second above even when caky trends is preferential.
But no matter make consumed group first,still be shutter preferential, need to match through adjusting the other condition such as speed to make when exposure correspondence reachs ultimate numerical value below the condition, very much even time should cooperate exposure compensation to get more exact exposure.
Whether did everybody understand shutter preferential with the characteristic with preferential aperture, the welcome leaves a message interactive.
