    Are you using a 10 stop? Looks like it's causing reflection.

    f11, 5 min exposure, no clouds in sky, this timing of shot... i also blur...

    to just have still water effect, dun think need 5 min exposure so long... since there is still light in the sky, 45sec-1min should suffice.

    don't need 5 mins.


    please don't tell me you didn't do some test shots to determine how long the exposure is needed before you set up for the shoot.

    Well, I always teach that anyone who shoots in bulb mode yet have a shutter speed that's odd number, clearly doesnt know anything about bulb mode....

    reposition...or use a lens hood or something better to keep strong light from straying into the lens

    2nd those who asked why you will need 5 minute exposure.

    There are many possibilities. One question I have is the compatibility of your holder and the filters you used. Gaskets provided by the filters may not match your holder if they did not come from the same source. I also seen some sellers in the market didn't even apply gaskets to 10 stop filters!

    Could you let us know more specifics about the lens you use, the filter holder you have too?

    If not, work with the shop that you got this from? If they are selling you these filters, I have to assume that they should be cluey enough to help you out.

    you may want to use back haida holder, lee holder may not be a good fit.

    check back my link above and think to yourself again why u need 5 min exposure.

    Looks like lens flare to me, turned into a hotspot because of the long exposure. Pointing into the sun will often do that to a greater or lesser extent, depending on your lens.
