2. whats a polarizer?

3. there are so many options, maybe someone could make a brief explanation of them. I see fog effect, diffusion filter, neutral density, skylight, spot filter (thats a strange one),


thanx

come on kid.... don't be like that. It isn't because I don't wanna help you, but I've forgotten all of that
you can find all of that with google.

I've seen a couple of pages that have lots of info, and without the classic things like "I believe that a filter with that color makes X oy Y thing"

1) I guess it's only purpose is to make a photo in a shade of a specific colour. A blue filter for example will give the picture colder colours.

2) A polarizer filter reduces the amount of light flare against reflective materials ie. chrome. Also the colours are more saturated. For example, when I take pictures of a monument whilst kneeling and the camera pointing to the sky, the monument will have nice colours yet the background will be totally white. With the filter, the sky will have it's natural colours.

3) Ask TT

I'm not an expert on photography so somebody correct me if I'm wrong. Hope that helps.

if you can download or have the focus st video from TG, you'll see what can a filter do.
JC pulls out a couple of filters and puts them in front of the camera.

There are indeed many different filters, but well, they usually do for different uses. If like me you mainly shoot cars, the only one you really need is the polarizer. To have a technical explanation google is your friend, but basically it is used to kill light reflecting on a given surface from a certain angle. You can rotate it in the position you prefer, to kill sky/clouds reflections on a windscreen, bonnet or on the sides of a car. Of course doing so it reduces the light coming in your camera :arrow: slower shutter speed, so especially with long focals a stabilizer becomes VERY handy, or a tripod, especially on cloudy days obviously.

The colored ones are just for fun IMO LOL.

Thanx guys, i just can't wait to get in to the photography course the next semester

also did my homework http://www.2filter.com/faq/filterfaq.html

google is the key. you'll always obtain more technical info about photo itself on the internet.
But you'll have more common advises to photograph cars here in JW

Well, they are intended for analogue-photography, where you can't adjust whitebalance on the fly etc. Also in b/w-photography they give different effects. Red for example gives lots of contrast in clouds etc, while green makes vegetation stand out.

[TT]

Ah lol indeed not having white balance adjustments must have been painfull

[MartijnGizmo]

The only other usefull filters for digital photography are graduated ND filters. They help prevent overexposing the sky in landscape-shots, something that's hard to achieve for example in Photoshop.
