    Dark spot on Photos

    Canon SD870IS
    I get a dark spot in the upper right corner in photos taken using the telephoto. No spot unless telephoto is used.
    What is the problem?

    Is it the same lens? that you always see the spot? or do you see it when you use different lenses?

    Re: Dark spot on Photos

    Since he hasn't replied yet.... I'm having the same problem. I actually googled this and this thread came up. Here's a sample:



    the rest of the spots are on my car itself. I needed a shot of something one solid color to show the spot ;)

    also, it's not on any of the lenses. when I look through the viewfinder, it doesn't show. It only shows AFTER the picture is taken (on the screen). Please help!

    Looks like dust on the sensor.
    If it looks more obvious and sharp when you stop down to f/16 and it almost disappears at f/2 then it's definitely dust on the sensor.

    eh.. I'm not sure what f2 is ;/ but my friend looked at it yesterday and said it's probably on the sensor. So how to fix it?

    I took mine to a camera store where he opened up the camera, turned it upside down and used a rocket blower.
    Never blow into your camera because you will cause condensation to enter from your breath.
    Take it to the camera store and get them to show you how to do it properly.

    Re: Dark spot on Photos

    There are several 'how to clean sensor' threads in the 'help' forums. Can be done by yourself but may be good idea to have it done at a shop first to see how it is done.

    If you are comfortable handling your camera... this is my favorite camera sensor cleaning site/ products... they have great totorials how to clean, and how to shoot the pictures which will show you dirty sensor... I shoot horse shows so I have to clean my own sensor... or I would nEVER have my camera back from the shop...lol...

    I think the black spot is due to dust partical. Art pictures commission portrait and prints play an important role in home decorating for several reasons. They do not only reflect and put your own personality into the room, but they can also help as a solution to change the look and feel of a room by giving the illusion of height, width and length

    Re: Dark spot on Photos

    Hello folks,
    Found this site and this thread by searching for solution on my less than a yr old Sony A300 camera. Recently I'd notice a right top and bottom black corner spots when I took pictures with zoom out to max, does not happen when I zoom back in a bit.
    Any solution for this, TIA.



    Right rotate to top,

    Re: Dark spot on Photos

    Kit lens? If not, what lens? Is the image different than the viewfinder? Do you have filter(s) or non-stock hood on the front of the lens? Does your SSS indicator flash all the time (lower right in viewfinder)? - TF

    Re: Dark spot on Photos

    Looks like vignetting but shouldn't happen when zoomed out. Should only happen at widest angle.

    Re: Dark spot on Photos

    I use kit lens.
    Same in the viewfinder that’s how I found out and zoom in a bit to have normal images.
    I have the polarizing filter when took these pictures, did not try without it yet.
    I believed the SSS bar only jumps up and down at the LCD not viewfinder, I can double check it tonight.

    Re: Dark spot on Photos

    ok, with the Sunpak 55mm circular polarizer off from the camera I don't see any black spots on the right top and bottom corners. Should I buy a different filter? if so recommedation on brands.

    Re: Dark spot on Photos

    If you were zoomed all the way out ( aka the widest angle) do you know what the length of the lens would be? is it a 18mm or what?

    depending how low that number is, no filter will fit on with out vingetting, its just a fact of life.

    Re: Dark spot on Photos

    You started by saying that it only happens when you, "zoom out to max" which, to me, would be 70mm. You meam at 18mm, correct?

    As was said, any filter will show up at 18mm on this lens. You will just have to frame a little larger and crop it off.

    My concern is why it is uneven. It should show the same amount of vignetting in all four corners unless the sensor is not centered. Did you check to see if the SSS indicator is flashing?

    Re: Dark spot on Photos

    Yes at 18mm.
    From viewfinder the SSS flashes all the times until I zoomed to near or at 18mm.
    From liveview it seems to flashes all the times no matter at 18 or to 70.
    TIA.

    Re: Dark spot on Photos

    I taking a stab that your using filters which fit into a holder (Cokin) and the holder in one is square and the other its at an angle, so only affecting one corner. It happened to me a long time ago on a film camera and took me a while to figure out what was happening.

    I was rotating the polariser and the holder rotated with it.

    Re: Dark spot on Photos

    I think that we’re getting somewhere.
    Just removed the filter to check for square or angles from the filter or on Sony lens but could not see any, but I did making sure that the filter screws in while the camera lens not rotating with it and now the SSS stop flashing at 34mm on both Viewfinder and Liveview. But the right dark corners are still there at 18mm but less, I can use it at 19mm.
    Should I worry about not centered ?.

    Re: Dark spot on Photos

    If the SSS indicator in the viewfinder flashes all the time (not the little bars going up/down, but flashes) - even when SSS is turned off - it means that it is broke. When it dies, the sensor stops at some point in the movememnt and may be off center. This would explain why only the two corners are dark. - TF

    Re: Dark spot on Photos

    Then again, here is a shot with my A350 at 16mm. These aren't even either and if it was 18mm, it might only show in two corners. - TF
