Hood classification and purposes
Many times we see others pretend long lens, front always with a Panasonic Lumix DMC-ZR1 Charger big hood, it feels like very professional, but everybody know hood true purposes? Now let us know about.
Hood purposes
Hood (Lens Hood) is installed on camera Panasonic Lumix DMC-FZ15 Charger the commonly used photography accessories, before metal, hard plastic, soft rubber and other material. Friend name is thought of justice, hood function is blocking extra light. The camera lens by more pieces of DangYang illumination, scored after a shot, the light will constantly reflection in the lens and lenses, generating between ghost or cause Meng feeling, photo ash can help to improve so hood image quality.
The blue line is normal in the optical path when into. Gray line is the interference light, the light around the bottom of the edge by lens reflex (red line) which, when light forward again with lens front, and back to the sensor produces reerberation produced the phenomenon of halo.
When light into JingShen conical shape, as a JingShen, but the shielding will blocked the light orthotropic don't need to become rectangle, so our image to see pictures will is rectangle and not round. Thus we can think like JingShen, on imaging, enter the light should help is a Panasonic Lumix DMC FS7 Charger rectangle four cone rather than cone, so the lens hood is effective blocking extra light, have installed hood photographs generally has more rich color and more in-depth saturation.
Filtering unnecessary light
Hood sort
1. Petals form hood
Petals form hood is in order to match the need of visual Angle camera around, so will the short and do some comparison is a few longer, petals form hood is formed in order to facilitate the formation of the light above four cones. PANASONIC LUMIX DMC-ZS3 Charger
2. Long hood
Hood longer, more separates light interference, reduce around the better effect on halo soundscape, so use long hood helps lens into light concentrate more.
3. The short form hood
Relatively, short form is more used to the wide-angle lens hood, Wide) lens (because the wide-angle lens needed to draw more light than a soundscape, thus obtains more broadly scenery.
On the market hood has have greatly small, everyone should follow lens size to purchase the right hood, such as 52mm lens (note 52mm does not mean the focal length of the lens, but lens size) should buy the hood, 52mm 72mm 72mm should buy the hood to cooperate.
Scenes from the lens size can find
Use the hood of benefits
Hood in addition to stop excess light outside, still have other benefits:
Use Panasonic Lumix DMC-ZS1 Charger hood can protect lens, hood can make unexpected touch and damage the surface of the mirror opportunity decreases
Hood can avoid by rain and dust affect lens
When the camera not carefully falls to the ground, hood help reduce generated by fall into the damage
When not using hood?
Also use the wide-angle lens and built-in flash light, hood have a chance to stop the flash light, forming shadows
You can use the filter (such as CPL began buying turns, hood might interfere with filters use Battery Charger
