렌즈를 낀 상태에서 수영을 하거나 따뜻한 물로 하는 탕 목욕하는 것은 피하세요. 수영장, 수로, 욕조는 박테리아, 세균, 그리고 때로는 화학물질을 지니고 있습니다. 튀는 물이나 피부에 닿은 물이 눈과 렌즈에 들어갈 수 있고 이는 렌즈를 망가뜨리거나 오염시킬 수 있습니다.
A pinhole digicam with a large aperture is blurry simply because Each and every pixel is essentially the shadow in the aperture stop, so its sizing isn't any more compact than the dimensions of your aperture (3rd graphic). Listed here a pixel is the world with the detector exposed to light from a point on the object.

Various forms of digicam lenses, such as large angle, telephoto and speciality A digicam lens (often called photographic lens or photographic goal) is surely an optical lens or assembly of lenses used along side a digital camera system and system to generate visuals of objects possibly on photographic film or on other media able to storing a picture chemically or electronically.

The complexity of the lens — the volume of things and their diploma of asphericity — relies upon upon the angle of look at, the most aperture, and supposed value issue, between other variables. An Severe wideangle lens of large aperture need to be of quite complex building to suitable for optical aberrations, that happen to be worse 바슈롬 at the edge of the sphere and when the edge of a giant lens is employed for graphic-forming. An extended-concentration lens of modest aperture can be of quite simple construction to achieve equivalent graphic top quality: a doublet (two elements) will generally suffice.
From the front of the camera, the modest hole (the aperture), could well be viewed. The virtual graphic of your aperture as witnessed from the entire world is called the lens's entrance pupil; ideally, all rays of sunshine leaving a point on the item that enter the doorway pupil might be focused to the same position on the picture sensor/movie (provided the item point is in the sphere of see). If a person were Within the digicam, one would begin to see the lens performing as being a projector. The virtual impression from the aperture from Within the digicam will be the lens's exit pupil.
