Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filter for photography. Along with the recent advances in photographic technology, various filters have been developed according to the purpose and application. The choice of these filters is the most important part of photographers.

[0002]

[Prior art]

 In the conventional filter for photography, one type was set in the camera for shooting.

[0003]

[Problems to be solved by the device]

 It was very difficult to compare the effects of several filters when the subject changes from moment to moment. Shooting with the most appropriate filters relied on the cameraman's experience and good luck. Therefore, shooting with the filter that seems to be the most appropriate cannot be carried out depending on the nature of the subject, creating a problem that the photographer is dissatisfied.

An object of the present invention is to make it possible to easily and quickly select an appropriate filter even when the subject changes momentarily.

[0005]

[Means for Solving the Problems]

 The figure is an explanatory view of the configuration of the present invention. In the figure, 1 is a multiplicity of filters. 2 is a filter carrier (slide), which is set in the holder of 3.

The holder 3 can be installed in the front part of the camera as shown in FIG. 2, or can be left stationary between the subject and the lens as shown in FIG.

[0007]

[Action]

 In the present invention, since various types of filters (infrared, ultraviolet, visible range, etc.) can be instantly slid and exchanged for use, even when the subject changes momentarily, various filters are used and conditions can be changed. It is possible to change the shooting.

[0008]

【Example】

 In Fig. 2, the slide holder for the lens is combined with a slide-type multi-sided photography filter and attached to the front of the lens. Further, as shown in FIG. 3, it is also possible to use a stationary holder.

As the filters, it is possible to select and combine various filters having different sizes and shapes (circular, square, etc.) and wavelengths according to the type of subject and shooting application.

[0010]

[Effect of device]

 As described above, according to the present invention, it is possible to quickly and easily select a filter, and it is possible to shoot under different conditions even when the subject changes moment by moment. Therefore, it greatly contributes to the improvement of photography technology in various fields.

Even if the subject is the same, it is possible to easily compare the effects of various types of filters.
