Abstract
The utility model relates to a composite pinhole photographic lens, which is used with a digital single lens reflex and can take digital pinhole photos directly. In the technical scheme, a semitransparent imaging screen replaces a film of a traditional pinhole camera, and an optical lens is arranged on the other side of the imaging screen. The optical lens is arranged on the digital camera, the digital camera can directly take pinhole images on the semitransparent imaging screen, and a camera shutter is used for controlling exposure.
Description
Technical field:
The utility model relates to a kind of compound pinhole photography camera lens, cooperates single anti-digital camera to use, and can directly take digital pin hole photo.
Background technology:
The pinhole photography photo have unique big depth of field, with great visual angle, dim imaging, strongly but not distortion of perspective, characteristic such as angle secretly naturally, pursued the professional photographer and the shutterbugs' of unique imaging effect and artistic environment favor deeply.
Carry out the pinhole photography creation at present, mainly still use film that the pin hole image is directly exposed, exist the predicament of finding a view, long processing period, exposure control difficulty, expense high, can not see shortcoming such as effect when taking at once, and at present, no matter be that works modification, storage or printing and publishing, network are shared, all need digitized video, the photo that uses traditional pinhole camera to take finally still needs to be digital photograph by the technical change that grades of scanning, electricity.
Though also can lead to the logarithmic code camera reequips, directly carry out pinhole photography with digital camera, but the image area sensor of existing digital camera is too little, and, be limited by camera structure, can't lean on pin hole and imageing sensor too near, take the visual angle and be restricted, be difficult to present the perfect effect of pinhole photography.If adopt the digital pinhole camera of picture of large image scale sensor production, then cost is very expensive, and domestic consumer can't bear.
Summary of the invention:
In order to solve the deficiency of existing pinhole camera, take digital pin hole photo with lower cost, the utility model provides a kind of compound pinhole photography camera lens, cooperates existing digital camera to use, and can take the photo with the identical visual effect of film pinhole camera.
The technical scheme that its technical matters that solves the utility model adopts is: the film that replaces traditional pinhole camera with a semi-transparency type imaging screen, opposite side device optical lens at imaging screen, optical lens is installed on the digital camera, directly with the pin hole image on the digital camera shooting semi-transparency type imaging screen.Shutter with camera is controlled exposure.
The beneficial effects of the utility model are: use this device, but under the intense light irradiation condition live view, can accurately control exposure, obtain digital photograph after the shooting immediately, do not have material consumption in the use, the cheap and environmental protection of expense.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a light path principle figure of the present utility model.
