Abstract
The present invention relates to a method and a special device for copying rephotographed backgrounds. The method is characterized in that an object and a background are respectively taken on the same negative film without mutual interference. The background shot by the present invention has high resolution, and false sensation to the combination of a foreground and the background is eliminated. A photographic work with a real foreground and scenery taken at different places which are naturally integrated in the same photograph when taking a photo indoors.
Description
The present invention relates to a kind of special effect cinematography method and device thereof, is that true foreground and people are given the system background to merge the method and the special device thereof of photography.
Existing closing in the scape photography has a kind of magic lantern that utilizes that background frame is projected in the screen, the projection method for imaging that true foreground and projected background are merged.This method makes in kind at the scenery photomontage of indoor shot acquisition with another place.But the background frame of this method be through projection on directional screen, make background resolution significantly descend.And be the high brightness that obtains background, the directional screen parts that are absolutely necessary.Therefore, the background resolution is low is that the weakness that the scape method for imaging is difficult to overcome is closed in projection.
The background that the purpose of this invention is to provide a kind of high definition, make the reproduction background have identical resolution with prospect in kind, to improve the true effect that closes the scape photography simultaneously, making the thing and the scape natural fusion that are in the strange land is the method for imaging of one, and provides the photograph technical design scheme of required device of this method of utilizing.
Fig. 1, background rephotographed attachment device and the camera site synoptic diagram thereof of taking pictures.
Fig. 2, background rephotographed camera and camera site synoptic diagram thereof.
Now in conjunction with the accompanying drawings and embodiments the present invention is described in detail.
Before the characteristics of the inventive method are to take camera 8, background positive 6, prospect in kind 2, object lens 4 are all placed (as shown in Figure 1) on the camera axis with orienting reflex screen 1.Flashlamp 10 places near the axis of camera 8, and when the reproduction background, the orienting reflex screen is thrown light on by object lens the light that flashlamp 10 sends with the background positive, on photographic plat 9, make it sensitization by copying lens 7 direct imagings.At this moment,, be lower than because of the luminance factor of prospect surplus the luminance factor ten of reflection screen times, say that relatively the brightness of prospect and screen brightness are shadows although prospect in kind is illuminated equally.Prospect in kind covers the reflected light of part orienting reflex screen, and the shadow that then stays next prospect in kind on egative film 9 is not by sensitization.When the prospect of shooting, the background positive is shifted out the visual field, prospect 2 is by flashlamp group 3 illuminations of illumination much larger than flashlamp, and imaging on egative film 9 makes it sensitization through object lens 4 and copying lens 7.The flashlamp group then by the direction of reflection screen reflected back flashlamp group, can not enter photographing object lens according to the light beyond prospect in kind, and historical facts or anecdotes thing prospect occupies outer part (being background parts) all can not sensitization.Utilize this method to finish reproduction background and shooting prospect respectively like this, make it all sensitization on same egative film, and do not disturb mutually.
Another characteristics of the inventive method are to establish half transparent image screen 17 near background positive 6.Imaging screen is positioned at outside the prospect imaging surface in kind, and prospect then in kind is blurred contour on imaging screen.When the reproduction background, the shadow that stays prospect partly is blurred contour like this.The scape that closes that adopts this method to make can the elimination prospect similarly be the feeling of unreality of cliping and pasting on the background, reaches the artistic processing requirements that satisfies photography.
Characteristics again of the inventive method are between object lens 4 and camera lens 7, near the imaging screen 17, establish a field lens 11.It can make the light by object lens 4 all enter camera lens 7, guarantees prospect in kind imaging on egative film.
According to the principle of the inventive method, designed a kind of background rephotographed attachment device of taking pictures.Its project organization signal as shown in Figure 1.Object lens 4 and copying lens 7 that this device uses camera 8 commonly used and market to purchase, its characteristics are that camera 8, object lens 4, camera lens 7, the background positive 6, field lens 11, the imaging screen 17 that connect rotating mechanism 5 are in-line to be arranged on the support 18, the seat top adds light-proof housing 15, and sets up programming controller 19.
Before scene is closed in shooting, attachment device, prospect in kind and orienting reflex screen are placed on the axis of camera.When the reproduction background, the background positive is opened flashlamp in the camera axial location, and the orienting reflex screen is thrown light on by object lens light with the background positive, at egative film, make it the sensitization reproduction by the copying lens direct imaging.Prospect has covered the screen reflected light, stays a fuzzy prospect profile simultaneously on egative film.Make the background positive shift out the camera visual field when stirring rotating mechanism, open flashlamp group illumination prospect, then through camera object lens 4, make the whole light by object lens 4 enter camera lens 7 by field lens 11, imaging on egative film 9 makes it sensitization and takes pictures.Then by the direction of backflash light modulation group after the screen orientation, do not enter camera lens 4 according to the light outside prospect, make all not sensitization of background parts, so promptly finished the photographic work that closes scape.
Another embodiment of the inventive method: the isolated plant of background rephotographed camera-the inventive method (as shown in Figure 2).
This camera has general camera function, have object lens 4, egative film 9 and shell 20, its characteristics are to be provided with between egative film and the object lens rotating mechanism 13 of turning 45 degree, have reflective mirror 14 in the mechanism, establish imaging screen 17, background positive 6 and field lens 11 above rotating mechanism.Copying lens 7 is established reflective mirror 12 for four jiaos in the shell 20, and is become miter angle with the camera axis at the egative film rear side.Light can pass through on the object lens direct projection egative film 9, then is general camera function, is used for the shooting prospect.Become 45 degree with the camera axis when opening rotating mechanism 13, i.e. position as shown in Figure 2, the light then reflective mirror on rotating mechanism reflects, through imaging screen, background positive and field lens, four jiaos reflective mirror and copying lens, reflective mirror 14 on reflective mirror 12 and rotating mechanism 13 enters on the egative film 9 again.At this moment, can be used for finishing the reproduction background.Framing eyepiece 16 is located at angle on the camera, sets up programming controller 19 simultaneously.
When using camera of the present invention, the prospect in kind back side will be set to the reflection screen, and flashlamp group 3 is used with flashlamp 10 in addition, and reproduction is closed the scape overall process and can be finished in 1/30 second by programming controller.
Use the present invention, can distinguish reproduction background and shooting prospect material object, sensitization and not disturbing mutually on same egative film, the background positive be by the direct reproduction of copying lens on egative film, the sharpness of background is improved greatly, the shadow of the prospect in kind that stays when the reproduction background is a blurred contour, the prospect of both having eliminated looks like to clip and paste the feeling of unreality in background, also satisfy the artistic processing requirements of photography, reach in pickup and can obtain a true foreground and strange land scenery natural fusion is the photographic work of one.
