    i was looking through some photos and flickr and now i have a few questions..

    so, how do you get the water to "Flow" in waterfall photos?

    and also, how do you create photos like this, where there is obvious motion, but the photo is still properly exposed

    Slow shutter speed (on a good support to avoid handheld blur).... with the appropriate exposure. The exposure is established by using a small aperture, lower ISO, and or an ND filter.

    Long exposures. Generally either by stopping the lens down and/or decreasing ISO (for a resultant increase in shutter speed) or better yet by using neutral density filters to give you a longer exposure time. "Flowing" water is usually about 2-4 seconds. I often stack 2-3 ND filters to get what I need on a bright, sunny day...

    yup
    Just a tripod + long exposure

    if its bright out then a ND filter is needed.( basically a dark piece of glass in front of the lens which allows it to be open for longer period of time)

    ah, i've been doing long exposures but they become overexposed. so a neutral density filter is what i need?

    As usayit said... you also need you make sure you have a small aperture (high f stop number) this prevents the amount of light entering the camera...

    A ND filter will definatly help.... but if you have a polarizer in you bag try that first.....

    As has been said alredy small aperture (f/22, f/32 or f/64) with med-long exposure.

    You can also do it in low light situations that may require you to wait untill wether is right or late evening if the ND filter is out of reach.

    I had the same problem... but I've found that even an exposure of just under a second can create the flow..
    Manual mode.. lowest ISO, highest aperature and a tripod (or other support)

    yeah
    just keep messing with it. an ND filter isnt needed.. but will help alot.
    if no ND filter you just need to wait until its getting dark out, or a cloudy day.

    those 3 were taken without an ND filter.
    it was just a darker day outside.

    http://coop81.deviantart.com/art/port-may-18th-85968416

    that was taken with an ND and a polarizer filter on.
    long ( il have to look biut it was like 20-30 seconds) exposure to give the smooth water effect, as it was really wavey, they were splashing over the whole pier.

    http://coop81.deviantart.com/art/Port-lighthouse-3-84178165

    this was also with an ND and polarizer on, 30 second exposure.
    but it was also at about 9:45pm.


    the pic you posted on the escalator you prob wouldnt need a ND filter at all.
    just get a tripod and set it on the stair, then set your appurature to the smallest ( ie f22) then take a like 1/2 second exposure. ( depending on lighting in the building you will have to change that up a little)
    or you could try shutter prioirty mode and see what that gives you as it will do the fstop for you to get the proper exposure.

    The escalator picture would actually be pretty easy I think. They are inside so the light is already lower...so I'm guessing the photographer just focused on the stationary corner of the step and played with exposure until he/she got it right.

    The other cool thing about polarizers is that if you rotate it correctly you can see what is under the water as well! :)
