What kinds of filters do I need?

I've had chances to take some night shots, but I got those "finger prints" lookalike on many of my photos, what kind of filters will get rid of them for good? of is there any web site that explain all different kinds of filters? Thank you.

Here are the examples:

what you have is lens flare as the result of shooting into a bright direct light.

No filter will take this away.

you need to be careful about pointing at a bright object (light source) which is directed at the lens. In this case it is the headlamps on the cars.

Thanks for the advise...

How about the second pic? there is no light around except a light on the ground that shooting towards the people I am shooting. Is that also the lens flare? ... I guess I can only be careful...

I agree it is lens flare in #1 but number two may actually me a smudge on the lens. Sounds silly but I have done it once or twice myself check that and check into a lens hood to help with the flare.

i think #2 is also a form of flair, due to the bright lighting off the falls.

if you look there is a repeated pattern of internal reflection just like #1 i can't believe a symetrically repeated smudge on the lens.

the only difference is that in #2, I would be willing to bet that the lens is wide open, as opposed to #1 which is stopped down slightly

You can't eliminate flare, but lenses with "ghostless coating" (late FA or new DA's) do a very god job of reducing it, even in direct light.

I keep UV filters on all my lenses to protect their front elements (i.e. my FA* 85mm), but always make sure you're buying the right kind of filter, since some low-quality filters actually add a type of haze to your photos! And don't forget to have a hood on each wide lens!

BEWARE!!! Don't be confused by filters which claim to "reduce reflection" - they reduce the reflection caused by the filter itself - but if you're doing night shots like this, it has to be NO FILTER! Filters at night = reflections. Good filters means less reflection - from the filter. You will still get some reflection from the lens AND the filter!

WHAT YOU NEED IS A HOOD - and you can even extend the effect by blocking bright lights which are "out of shot" with your hands even.

But if the lights are in the shot and causing reflection, in the end all you can do is try a different angle or something.

Thanks everyone for the reply.

I think I need to have my hood on all the time, even at night... ... I thought the hood is for sunny day only before... @_@
