Description
Technical field
The utility model relates to a kind of photography and shakes black card device with portable.
Background technology
In landscape photography, take pictures especially the photos such as sunrise sunset time often run into a problem, that is exactly that dark portion will be very dark with the photo photographed during sky outage light part light-metering.If but during with dark portion light-metering, then will to be that a slice is pale make photo sky overexposure to sky outage light part.
Black card technique is shaken in order to address this problem just to create.Concrete enforcement is that a dim light mirror to be enclosed within before camera lens to force down logical light quantity by cameraman, so just can obtain the longer time shutter, with can with hand-held black card control exposure.First with some light-metering to sky outage light part light-metering, be such as 4 seconds be 30 seconds to dark portion light-metering gained again, difference 26 seconds between them.Such cameraman just can with a black block before camera lens, high light and dark portion intersection, fluctuate with certain frequency (under 4-5 per second) and certain amplitude (1 centimetre), black card, first expose and then rapid black card to be removed for 26 seconds, remaining 4 seconds of exposure again, a photo just can complete.Why to shake black card in exposure? avoid exactly leaving black card vestige when exposing.
Reaching 30 second time shutter needs people to remain certain amplitude and frequency, shakes its difficulty and well imagines, also will count the number of seconds exposed at this simultaneously.Needs are also had to mention, be exactly that slr camera is when exposing, reflector lifts, picture is can't see in finder, like this we shake black card position can't see, take pictures and can say so shake black card each time and felt completely, this to shake black card technique be the gimmick that large light ratio photo often uses of taking pictures at present, even photography master-hand, absolutely success also can not be accomplished when shaking black card and taking pictures.
At present, automatic black card device technology is had to solve the problem.Patent of invention " camera black card device (patent No. 200510100081.3) " proposes the black card aut.eq. of camera, but the defect that this automatic black card device exists has: this device is directly contained in above camera, black card swings up and down and can produce vibrations, can have an impact to camera imaging; Complex structure, complex operation, cost is higher, expensive; Electric Machine Control needs loading routine or instruction, uses loaded down with trivial details.Need black card to remove fast after height light Partial exposure when shaking black card, this patent is not mentioned and how to be realized, and many parts may be divided to have blocked once photo taking shaking black card, its device can not complete.
In view of this, the utility model proposes an automatic photography and shake black card device with portable, the utility model is exactly produce in this context, to realize a kind of portable, easy, easy-operating black card automatic rocking device.
Utility model content
The purpose of this utility model is to avoid the Problems existing in above-mentioned background technology and not enough and a kind of photography between automatic and manual operation that is that provide shakes black card device with portable.It both can realize shaking the function that black card technique takes large radiograph, can reduce again the workload of photographer and improve the accuracy of at every turn shaking black card, solving the problem of manually shaking black card; The feature of device and camera split avoids black card and swings up and down the vibrations produced camera, have again that structure is simple simultaneously, highly versatile, flexible operation, feature lightweight, with low cost, solve defect and the deficiency from shaking black card device.
The purpose of this utility model is achieved in that and connects a disk with a reducing motor, and disk fills an eccentric pin.Connect a slide plate with connecting rod, the line activities becoming and slide up and down is moved in the transhipment of determining of motor.The amplitude slided up and down and frequency imitate the action of manually shaking black card.During use, black card only need be cut into required beginning by cameraman, is then contained in lock-screw on slide plate, by slide plate pulled down to minimum point, before being placed on camera lens, and high light and dark portion intersection.This device hand-held is motionless, trips, and presses the button on lower device, then easily completes shooting work by the exposure of watch hand data.
The utility model is compared with background technology, and tool has the following advantages:
(1) motor power consumption is very little, and powering with 2 pieces of button cells just can work really long days;
(2) lightweight, with hand-held just can easy manipulation;
(3) black paperboard convenient mounting and clamping, firmly, black paperboard can be convenient for changing and open;
(4) use flexibly, easy to adjust;
(5) accurate positioning, shake amplitude-frequency is stablized, and has very strong practical value.
Accompanying drawing explanation
Fig. 1 is the utility model device inner structure floor map.
In figure: 1, motor; 2, button cell; 3, slide plate; 4, lock-screw; 5, black card; 6, disk; 7, connecting rod; 8, clamping plate; 9, button; 10, general supply gauge tap; 11, casing.
Embodiment
As Fig. 1, the utility model is made up of motor 1, button cell 2, slide plate 3, lock-screw 4, black card 5, disk 6, connecting rod 7, clamping plate 8, button 9, general supply gauge tap 10, casing 11; Two pieces of button cells 2 connect motor 1, connect a disk 6 with a reducing motor 1, and disk 6 fills an eccentric pin.Connect a slide plate 3 with connecting rod 7, eccentric pin, connecting rod 7, slide plate 3 form gear train, and gear train is placed in casing 11, and this device can move the transhipment of determining of motor the line activities becoming and slide up and down, and the amplitude slided up and down and frequency are fixed.During use, black card 5 only need be cut into required size by cameraman, is then contained in lock-screw 4 on slide plate 3, by slide plate pulled down to minimum point, before being placed on camera lens, and high light and dark portion intersection.This device hand-held is motionless, trips, and by the shift knob 9 on lower device, then easily complete shooting work, hand-held device half-twist by the exposure of watch hand data, black card can do side-to-side movement.This device is placed in bag or in luggage case, and for preventing touching shift knob 9 easily thus automatic starting device, general supply gauge tap 10 can be closed, Switching Power Supply 9 lost efficacy, and causes misoperation to avoid button 9 to be touched unintentionally.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have the same or analogous technical scheme with the application, all drops within protection domain of the present utility model.
