Description
Technical field
The utility model relates to photographic goods field, specifically refers to the color filter lens package structure that a kind of centre wavelength is adjustable.
Background technology
Along with camera work development be gradually improved, the requirement of people to photographic goods also improves thereupon, filter is as a kind of supplementary mode of Professional Photography, and a kind of photographic accessory the most common, the visual effect that naked eyes at ordinary times be can't see can be realized, be widely used in Professional Photography, field of photography.
Filter conventional at present mainly comprises UV mirror, polariscope, gradual change mirror, gray out, dim light mirror and color filter etc.UV mirror can ultraviolet ray filtering; Polariscope is also known as PL mirror, only accept the light of single direction, get rid of the light of reflection, effect is exactly to photograph more blue sky the most intuitively, the object of shooting inside glass does not have reflective yet, is the filter that can improve picture that current each large-scale commerce camera mechanism uniquely accepts; Dim light mirror is also known as ND mirror, and its use is exactly the luminous flux being decreased through filter; Color filter is mainly used for intensifying when taking black-and-white photograph, such as red filter can absorb blue light, produce the effect at romantic sky effect or shooting similar moonlit night on daytime, for forcing down the color of sky and creating beautiful contrast to cloud layer in black and white landscape photography, black-and-white photograph does not have photochrome so gorgeous after all, realizes enough large contrast and can create the sky effect very with impulsive force.
But with regard to filter conventional at present, the filter of a type can only realize single visual effect usually, if need to reach multiple shooting effect, then need multiple filter superposition, compound use, this is very inconvenient concerning the photography of field.Meanwhile, different from simple later image process, due to the use of filter, the image effect of shooting is irreversible; Once employ filter irrelevantly, may form to the image of shooting the harmful effect being difficult to retrieve.
Utility model content
The purpose of this utility model is the color filter lens package structure providing a kind of centre wavelength adjustable, solve current filter color filtration single, use colour filter cause the irreversible problem of shooting effect, realize the function of multicolour filter.
The purpose of this utility model is achieved through the following technical solutions:
