Description
Technical field
It the utility model is related to a kind of camera and its servicing unit, especially a kind of particular exposure apparatus for camera
And camera.
Background technology
We always inevitably meet when shooting honourable some big light than environment, i.e., ought up and down light than anti-
When difference is excessive, be exactly briefly to highlights when dark portion light-metering is foundation can serious overexposure, or to dark when highlights light-metering is foundation
Portion then it is black arrive without details when, and camera be different from we can visually automatically adjust, the limited tolerance of camera can not
Take into account bloom and dark portion well.Such as sky and ground, if light, than excessive situation, we have shot rear it finds that will
Or a piece of dead black sky of dark portion is a piece of dead white.This when, we will solve problem by some special means
.Such as：Shake black card technique.Black card technique light and shade portion transition is shaken naturally, color rendition is true, but needs photographer to shake black card in person
（Black card is one piece of light tight, non-reflective object）, difficulty is controlled, success rate will just be held the bottom of compared with the case where exposure is longer
Easily success.The use principle of black card：Everybody is only needed before shooting, in highlights and dark portion difference light-metering, then calculates both light
Than.In other words, as the gap of shadow exposure time and highlight exposure time.Afterwards appropriate portion is blocked using black card
Point.From top to bottom, mirror before camera lens is pressed close to, bright position is arrived in covering.So, highlights can be allowed to be hacked card coverage.
For example：Sunrise or sunset photo are shot, after light-metering calculates, sky portion needs exposure 1 second, and
Ground then needs 10 seconds, and that just blocks camera lens top（Clap the part of heavenwards）9 seconds.Black card is removed afterwards, it is possible to allows ground
The part of sky only exposes 1 second while face obtains exposure in 10 seconds.In this manner it is possible to reach it is anticipated that effect, allow dark portion
All remained with the details of highlights.Such as photo is hacked the local of card covering and there is huge without covered place
Exposure value difference, therefore obvious seam side together occurs, offends the eye very much and unsightly.At this moment, we can shake black
Card, to desalinate seam, allows photo to seem more natural.But to be paid attention to, if application method is improper, it is possible to allow photo to go out
The vestige of existing black card.Therefore, action can not be too slow, in order to avoid the mirror that is ingested.Therefore it is high manually to shake requirement of the black card to photographer,
Frequently result in operation failure.
The content of the invention
