    Hey, Im new to photography. The last yr just learning through trial and
    error to take clear, nice shots.
    I feel good enough now to start experimenting with filters.
    Can you put more than one filter on at a time?

    Thanks for your help

    Short answer. Yes, you can. The long answer requires you to think about the
    filters you want to use, and the desired effect. I always have a UV filter
    on my lens no matter what. They only cost about 10 bucks online and protect
    you lens from scratches and finger prints and dust and etc. Much cheaper
    then replacing lens glass. Then I just screw on the next filter that I want
    to use. i.e. polarizing. Just be careful on how many you put on. Any more
    that 2 or 3 might give you a shadow ring on your picture. Which can be a
    cool effect if you want to use it some how, but also can be a real bugger if
    you didnt plan on having it there. ;o)

    In many cases you can. Most filters have threads in the front that
    allow another filter to be screwed ontop of it. Some slimline filters
    don't have the front threads.

    In some cases, though, you may not want to do this, because the
    additional filters may cause vignetting. This happens primarily on
    wide angle prime lenses or zooms with wide angle capability...however,
    it can happen on other focal lengths as well, just depends on the
    particular lens.

    There are some combination filters made, such as Skylight/Polarizer or
    Warming/Polarizer, which combine two filters into one.

  4. The filter factors have to be considered as well, as they are additive. The
    more you use the less light entering the lens, and the greater exposure
    needed. Cameras with through the lens metering should alert you to an
    appropriate setting, but some head scatching and calulating is in order when
    using a hand held light meter.

    I'd be interested to know what specific combinations of filters he has in
    mind . . .

    He says that he is going to "start experimenting" with filters, and that he
    has just learned, through trial and error, to take "nice clear shots."

    I get the feeling that the term "filter factor" probably doesn't mean a
    thing to him, at his current level of expertise.

  6. Well perhaps, but would not the rest of my post let him infer that filter
    factor refers to the reduction of light transmission? It would though be
    prudent to say that filter factors are measured in stops. A 2x factor needs
    2 stops additional exposure, unless my math is as usual faulty.

    To answer your questions (hopefully)

    1) yes, you can put filters over filters. However, as others have pointed
    out, you have to be wary of vignetting. In other words, if you put too many
    filters on, vignetting is when the filters starting cutting off the image at
    the corners.

    2) some filters reduce the amount of light entering the lens. However, you
    most likely have a camera with thru the lens metering, so the camera meter
    will adjust for the filters

    3) with a polarizing filter, if you have a newer camera, you probably need a
    circular polarizer. If your camera is older, you might get by with a regular
    polarizer (but are regular polarizers available any more?)

    Now, sort of a soap box speech......

    Realize that I come from a photojournalism background. Thus, I sort of
    follow a minimalist approach to "gadgets" including filters. Other people
    will have different opinions.

    Use filters sparingly. When I started out with photography, I had visions in
    my mind of all the cool effects I could make with filters. Yes, they seemed
    neat then, but now, when going through my stock images, I cringe when I see
    all the Cokin filters I used. Personally, I think that the key to effective
    filter use is to create an image with little to no clue that a filter was
    used. If you want effects, scan it in and play with it with all the image
    enhancement software currently available.

    The filters I would recommend (if I may be so bold).....polarizer, gradiated
    neutral density, regular neutral density, a red one for black and white and
    black and white infrared (sorry, can't remember the number), and a SLIGHT
    warming filter.

    Focus your energy and creative passion on....
    - observing your surroundings. Many people with cameras are impatient, thus
    they take minimal amount of time to snap the shutter.
    - getting up close to your subjects. favor the 35mm lens range versus the
    telephoto range. the 35mm combined with getting up close to your subjects
    will pull your viewers in. yes, it's difficult to be comfortable operating
    so close, but learn how to do it before you learn how you can get neat
    effects with filters.
    - trying a bunch of different types of film. don't just stick with royal
    gold, kodak max, or whatever fuji and kodak are selling at target or
    walmart. try the pro don't have to be one to use them. try the
    high speed and low speed. try chromes. learn what type of film best brings
    across what you'd like to bring across...not what a majority in this news
    group say is the film to use.

    This is by no means an exhaustive list, but I need to get to bed. Above all,
    experiment, but don't think that a bunch of special effects filters make a
    good image.

    just a thought,

    Just to clear Polarizing Filters up a little. When you say old camera you
    mean a camera that does not have "through the lens metering" (TTL) and when
    you say new camera you mean a camera that has "through the lens metering."

    No TTL = Linear Polarizer (which are still available)
    TTL = Circular Polarizer

    Have we thrown enough information at you? :eek:P

    Not correct. A Canon AE-1 can take a regular polarizer, yet it has through
    the lens metering. The Canon F-1N (still an older camera) needs the
    circular. Many, if not all, of the autofocus cameras today need the
