Thread: Black dot

    Unhappy Black dot

    Hi guys!, I need help! I notice today that when I took a photo on the bright sky, there is a black dote which I don't know what . At first I thought is my lens dirty but when I change to another lens, the dote is still there at the same position. Is it my camera body dirty? I'm using Nikon D70s and sigma 18-200 lens and D70s kit lens. really need your advise. T hanks

    It could be dust on your sensor. Do you have a dust blower?

    no worries.

    Send to Nikon Service Center for sensor cleaning.

    Remember to check after they clean

    Steps
    (1) Stop down to f18, manual focusing
    (2) Fill the frame with white paper or just take one of the white background brochures there
    (3) Shoot and review to see if the dots are there or just shifted.

    Sometimes it takes more then one cleaning
    Cleaning is free during warranty, go more often!
    After that its 25, then consider using blower. seriously, blower sometimes add more dust if you dont know how to do it properly!

    Another option, use software to remove the black spots.

    Regards,

    A simple puff from the blower is usually enough to 'dislodge' the dust particle. If it's a stubborn stain, get it done at Nikon Service Centre.....unless you know how to do proper sensor cleaning.

    even after using a blower, there'll still be dust on your sensor, which become evident on long exposures. a sample from my camera which i took yeterday, and levels adjusted to show the dust

    20min exposure
