Description

필터 삽입공을 갖는 카메라 후드Camera hood with filter insert hole
본 발명은 필터 삽입공을 갖는 카메라 후드에 관한 것으로서, 더욱 상세하게는, 촬영자가 촬영중 피사체 또는 촬영자의 의도에 따라 필터를 교환할 때 필터를 신속하게 교환할 수 있도록 한 필터 삽입공을 갖는 카메라 후드에 관한 것이다.The present invention relates to a camera hood having a filter insertion hole, and more particularly, to a camera having a filter insertion hole so that the photographer can quickly change the filter when the filter is changed according to the intention of the subject or the photographer during shooting. It's about the hood.
일반적으로 카메라에 사용되는 필터는, 사진을 부드럽게 해주는 소프트톤 필터와, 레인보우 필터, 크로스 필터, 그라데이션 필터 또는 편광필터 등 다양한 필터가 있으며, 이들 필터는 특정 빛을 걸러준다는 의미를 담고 있다.Generally, a filter used in a camera includes a soft tone filter that softens a picture, and various filters such as a rainbow filter, a cross filter, a gradient filter, or a polarization filter. These filters mean that they filter out specific light.
이와 같은 필터는 사진에서 빛이 필름에 닿기 전에 혼합된 광선을 구성하는 파장을 선택적으로 변화시키는 데 이용된다.Such filters are used to selectively change the wavelengths that make up the mixed light beam before light reaches the film in the photograph.
필터는 유색 유리, 플라스틱, 젤라틴으로 만들어지며, 이들 필터는 대부분 카메라 렌즈 앞에 장착되지만 어떤 경우는 동일한 효과를 가진 광원에 놓일 수도 있다. 흑백 필름은 감색성(感色性)이 불완전해 착색 필터로 광선을 변화시켜 피사체를 인간의 눈에 보이는 것과 일치하는 회색조로 전환시키는 데 이용된다. The filters are made of colored glass, plastic, and gelatin, most of which are mounted in front of the camera lens, but in some cases may be placed in a light source with the same effect. Black-and-white films are used to convert the light into a grayscale that matches the visible to the human eye by changing the light beam with an incomplete color filter.
또한 착색 필터는 노출시 부분적인 대조를 가능하게 하여 유색 피사체를 밝게 또는 어둡게 재현할 수 있다. 컬러 사진에서 착색 필터는 필름의 감색성에 맞도록 빛이 지닌 색채를 변경하는 데 이용된다.In addition, the color filter enables partial contrast upon exposure, allowing bright or dark reproduction of colored subjects. In color photography, color filters are used to change the color of light to match the film's darkness.
종래 카메라에 설치되는 필터는, 테두리 내부에 렌즈가 마련되고 테두리에는 나사가 형성된 것으로서 대부분 카메라 렌즈 앞에 나사결합되는 구성이다.The filter installed in a conventional camera is provided with a lens inside the rim and a screw is formed in the rim, and most of the filters are screwed in front of the camera lens.
