    Default Glare/Dots in the Photo

    Hi Fellow Shooter,

    Newbie here and would like to know the problem of my cam I just shot tonight.

    A lot of black dots and glare in the photo particularly in the sky area. What is the cause of it?
    Cam or lens?

    BTW, I used D7100 + Tokina 11-16 DXII with B+W filter.
    Specs: 12mm, F22, 10Sec, ISO400

    bro, did u do a mirror up and check the sensor?

    also try viewing thru viewfinder or do live view on a white background. so are the black dots visible?

    for the flare, could it be due to filter?

    Black dots looks like on the same positions.. so maybe dust particles on the sensor... use blower should be good enough..
    Glare could be either lens or filter? oil smear/ worn out coating/ just inherent lens characteristic???

    sensor dust spot
    remove your filter
    and why you use ISO 400, f22 and 10sec?


    you can use ISO 200, f16 and 10sec, there is no need to have f22, unless you want to see more sensor dust spot and some star burst.

    and why you need 10sec? this place is too bright and not much traffic, you won't see much light trails.

    hmm just a side thought.

    I used a Tokina 11-16mm f2.8before but it was version one and it flared like mad even at the slightest light source. but tokina supposedly has improved the flaring in the version 2 with new coating. I don't think it should flare that badly in the second photo. perhaps it's the filter or some reflection off something?

    Same experience I encounter using the same setup (D7100 + Tokina 11-16).

    What I do is dial out F-no. down from F22 to F16 then to F11 then F8, and see if the flare thingy is still very visible. Mine usually got minimal with F11.

    Also try at slightly shorter shutter speed to minimise the creation of flare.

    That's for me; I play around with Aperture and shutter speed to minimise the flare (somehow tokina lens is pretty tough not to get any flare).

    Another best way for me is recompose to such a way the flare does not become bad.

    The lens is 1 week old and this was the 1st time I tried using it in night shot.

    Hi i do not think it is the lens but it looks like reflections on the filter you should remove it
