Problems solved by technology

However, this shooting method requires the two cameras to be synchronized in shutter, focal length, aperture, color, exposure, sensitivity and other aspects. It is very troublesome to adjust, and it is beyond the operation and control of ordinary people.
At the same time, due to the characteristics of the half-mirror itself, ghost images will appear in the shooting picture when the light and dark light are relatively large, which will seriously affect the image quality.
In addition, you can use the method of stand-alone translation to shoot stereo macro, but this method is not suitable for shooting dynamic pictures

Embodiment 1

[0045] Such as figure 1 As shown, the camera is equipped with a shifting lens and a photosensitive element, and the shifting lens achieves The purpose of the perspective relationship of the photographed image or the focus of the whole area.

Embodiment 2

[0047] Described photographing method comprises telephoto lens reflection stereo macro photographing method in large aperture, and this photographing method comprises the following steps:

[0048] Step 1, the shooting device is placed horizontally, the shooting direction is vertically upward, and the object 51 to be photographed forms an inverted real image 61 on the photosensitive element of the camera;

[0049] Step 2, add a circular black opaque sheet filter 04 in front of the lens of the shooting device, the filter 04 is close to the front lens of the lens, a small hole is opened in the middle of the filter 04, and the light can only enter the lens through the small hole;

[0050] Step 3: Adjust the aperture of the lens to the maximum when shooting. The size of the small hole of the filter 04 should be such that no vignetting or black edges appear on the edge of the image during normal shooting. The small hole is the aperture of the lens;

[0051] Step 4, add a reflector 0...

Embodiment 3

[0057] Such as Figure 4 As shown, the shooting method also includes the position and angle setting of adding a reflector to the small-diameter wide-angle lens:

[0058] The reflective mirror 01 is close to the edge of the lens 02 and is perpendicular to the lens cross-section, and black edges do not appear in the image taken by the shooting device, and the object 51 to be photographed forms a symmetrical virtual image 52 of equal size with the reflective mirror 01 as the axis of symmetry; the object to be photographed and After its virtual image passes through the clear aperture of the filter 04 and the lens 02, it forms a pair of horizontal side by side inverted and symmetrical first image 61 and second image 62 on the photosensitive element of the camera; since the reflective lens 01 is not in the middle of the lens, the reflective lens The front end of the front end close to the bottom of the object deviates from the center of the image field, and the distance of the devia...

Abstract

The invention discloses a symmetric type three-dimensional microspur shooting method and a shooting device of a single lens reflex. According to a tilt-shift lens full-zone focusing principle and a plane mirror reflecting principle, a piece of front surface reflector is additionally arranged in front of a single lens, a shot object forms a symmetric virtual image in the reflector, and the lens records the shot object and the symmetrical virtual image with tiny parallax on a photosensitive element of a camera, so that the real-time shooting of a three-dimensional microspur image is realized. The method overcomes the defects of traditional double-unit shooting; firstly only the single camera is needed, and a lens device is additionally arranged, so that the camera is convenient to carry; secondly, the single camera shoots through one-time shutter, so that the synchronism is good; thirdly, the front surface reflector is adopted, so that a double image phenomenon cannot occur on the image.The symmetric type three-dimensional microspur shooting method and the shooting device of the single lens reflex provided by the invention are applicable to a large-aperture middle-long focal lens ora small-bore wide-angle lens, and have the characteristics of simplicity and practicability.

Description

technical field [0001] The invention relates to the field of photographic and photographic aids, in particular to a single-lens symmetrical stereoscopic macro photographing method and photographing device. Background technique [0002] Stereo shooting and display is the future development trend. As we all know, the lack of three-dimensional display content is one of the bottlenecks restricting the development of the three-dimensional industry. The content of stereoscopic display mainly comes from stereoscopic shooting, so the popularization of stereoscopic shooting method seems particularly important and imminent. [0003] Stereo macro photography is one of the important contents of stereo photography. Stereo macro photography is more difficult than general medium and long-distance stereo photography. At present, there is no product specially used for stereoscopic macro shooting. Generally, vertical double racks and half mirrors are used for dual camera combination shooti...
