    Yeah. It's used to prevent glare and lens flare and also to protect the lens.

    If I am not mistaken, beyond the flare prevention and lens protection, it is said to improve saturation and color as well. It prevents stray light rays from bouncing off the front elements.

    Ahuh, found an online verification for you

    Cheers~

    The improvement in saturation and color is a result of flare prevention

    Flare caused by unwanted incidental light internally reflecting within the elements can take several forms. Sometimes appearing like sunspots, sometimes it looks like a thin veil that lowers contrast and saturation

    so one thing, is it necessary to get a good hood? cos i went cathay photo store at penisular, and they told me that a rubber one would be good enough. and i bought it.

    As long as you get the correct one. Different lenses need specific hoods so that the hood will not vignette the picture. A hood for one lens may not be suitable for another.

    I dun carry hoods cause they are too bulky for me. I just use my palm or a cap that i bring along on trips.

    "The primary use for a lens hood is to prevent light from hitting the front lens element from the sides - reducing contrast and creating flare. Pictures taken with a lens hood installed will generally have richer colors, deeper saturation."

    From: http://www.the-digital-picture.com/C...ens-Hoods.aspx

    Hmm.. Sounds like a pretty noob question then... Will it serve any purpose in Night Indoor and Landscape Photography? Since stray light and all still exist and not so much on flare reduction? Don't wanna be labelled as a poser using a lens hood at night.. haha!

    Protection of the lens is also a factor.

    I have dropped a cam with the hood on face dow before and the hood absorbed the impact and cracked... well, it's far cheaper to replace a hood than a lens front element.

    if you're shooting under rain.. the hood will prevent water from going onto your front lens element or filter..

    At night there still is stray light, and I've encountered it quite badly when shooting night landscapes and there are many sources of stray light around. Especially on an UWA, where it is hard to stick your finger/hand in to just block the source of stray light, I keep my hoods on.

    Knowing which of your lenses are more prone to flare, and which aren't, also helps. For instance, I have one particular telephoto that is very prone to flaring, so I use that with the hood all the time, even though it's unwieldy to have it on such a long lens already.

    I use it to look more pro, and also it exposes the red ring.
    It is the camera, not the photographer.
