    i tried before...when i first got my camera...and i read from scott kelby's book...u don need a ND filter if u get the below rite...
    1) tune to lowest aperture, which i went down to f22
    2) use a CPL
    3) tripod mount
    4) Set ISO to lowest...
    5) Shoot at 6-7pm after sun set....

    i believe your pic was taken at night?

    mine was a freaking hot sunny day in the lovely tropical country, was so damn bright that the water reflects light like HID lamp for street racing... oh well, maybe like what chalib said, the lowest i went was the lowest my cam was capable of and apparently thats not enough... (ISO80 i believe is still alright, maybe its the aperture that needs to be improve. f8 still too wide? guess i shall have to live with it)
    hi ts, maybe you can try HDR as an alternative, it won't get the same effect as the one with filter, but at least it resolved the overexposure caused by the reflection from the water plus the added details from the shadows on the rock portion, here's the one i took at chinese garden on my 2nd month of owning a dslr so pardon my noob PP skills hehe:

    basically the problem, it is too bright for a slow shutter speed thus the over exposure
    if you are a newbie and do not yet understand exposure

    do not use manual mode

    1. mount camera on a tripod (to prevent camera shake using slow shutter speed)
    2. set your ISO speed to the lowest
    3. set your camera to aperture priority
    4. set your aperture to the smallest aperture you can (to cut the amount of light)
    5. shoot

    if it is not slow enough, you need to cut more light, you can do this by
    1. CPL (normally 2 stops)
    2. ND (depends on your filter)
    3. CPL + ND
    4. shoot when it is darker (twilight/evening)
    5. all of the above

    you can also bring a huge umbrella and cast a huge shadow over your scene

    only if the scene is small enough, if not you need an really, really, really big umbrella.

    even bigger than this

    thats very nice!

    mine was... argh. nightmare.

    pardon the poor and failed composition. wasnt really planning for anything cos just want to get the exposure right, hence, theres leaves on the left and people on the right

    i didnt try A-priorty but I got a feeling that it will choose a higher shutter speed and the waterfall silky effect wont be there.

    aperture priority mode will choose the correct shutter speed based on the aperture that you select, so you most likely will not get an overexposure.

    how about other methods? tried to minus exposure but doesnt work.

    today went botanic garden to shoot some waterfall, tried a 2 secs but the pic almost turned out white under the bright sunlight. should had put on the CPL filter (does CPL help)
    CPL defintely does helps as its equalivent to 2 stop ND (ND4) once polariszing effect is in place as it cuts out light...

    Lowest ISO, Smallest Aperture, Tripod Mount..

    Best bet is to invest in ND filters.. Lesson learnt, now u noe...

    I see.

    Which ND should I get in your opinion?

    Was thinking of getting a ND4, but after u said CPL also considered as ND4, that kinda defeat the purpose? (Or should I stack them?)

    Or just get a ND filter of ND8 (is it overkill?)

    u can those set one..for a newbie if u got budget constraint..can consider the tianya set...comes w many different ND and GND...

    if not, most of the time, i will just bring a ND8 with me...but bring a tripod...

    Again: read and understand the basics. If you had done so you could do the maths on your own. ND2 means: reducing the amount of incoming light to 1/2 (50%) - which means: 1 stop of exposure. ND4 cuts down to 1/4 (25%) = 2 stops. You get the idea? Now look back at your images, check the exif data and do some calculations. Based on your ISO, shutter speed and aperture you should be able to determine what kind of ND is required in order to get a silky waterfall.
    Sometimes you need to work through some more lines of text and simple quicks answer in 3 words is not sufficient. Light appears in many different ways, there are no "quick, works always" settings.
