    Did a mini photoshoot today and while importing the photos from the camera to LightRoom (version 3.6) I noticed these very intense black spots on one photo (rear taillight, front and rear fender)...

    9646271614_7e24a87a0a_b.



    They are NOT on the sensor since all my other photos from the set don't have them

    9645625272_a78e686c2a_b.



    Any ideas what it might be? Shadows perhaps?
    And, tips on how to remove them in post?

    TIA

    Just to make sure that the spots are not caused by dust on the sensor... try taking some shots of the sky or some other even-colored scene. like a beige wall or something with little or no additional coloration. and try both vertical and horizontal shots. then, if it is dust spots, they will definitely show up. However, on the first shot of the scirroco they do sort of look like shadows over the wheel wells. ???????

    Shadows maybe?

    Or reflections? Was the black car parked near the red car in the first photo?

    Thanks for the replies

    Tried the test for sensor dust and its not that

    Oh, and its a Corrado not a Scirocco :D


    Indeed the black car was parked near the red car :)


    Regarding the attempt for removal in PP, I tried the "spot removal" (LightRoom) with no success :(

    It's sensor dust, I suspect. The spots are identical in both photos, though (unless either shot is cropped) they seemed to have moved downward in the 2nd shot.

    No biggie. I get sensor dust all the time. Just order one of those LENSPEN sensor cleaners and have a little cleaning session. Easy peasy!

    If the spot removal tool doesn't work, simply use a cloning tool. Sometimes the old tools are the best.

    How about I try Sony's sensor cleaning mode first?

    Trying doesn't hurt, but it won't help. The basic sensor cleaning is activated every time you turn off the camera, so if that doesn't help, activating it manually hardly will help.

    No worry. I do it myself each time
    it is needed with Sensor Swab and Eclipse fluid. Works like a charm.

    Update:

    Spoke with a friend of mine who owns a photo service business (and takes care of all my gear) and I've booked my Nex for a wet cleaning session tomorrow. He adviced the wet cleaning vs the lenspen/blower method. Will probably have it back in a few days

    How much do they charge? Because my local camera store wanted €170 when I asked for a sensor cleaning ...

    He charges €50 so I guess that a good price. He's more like a home business though (not a big store etc) :)

    Even for 50, I'd do it myself. It's pretty easy with mirrorless cameras. But a professional clean can't hurt either.

    In my nearby photo store they will do it for € 40 which I still consider a bit on the high side, but on the plus side I'm only a few hours without a camera. I've had them clean my D300s once with good results, I always did mirrorless cameras myself with good enough results.

    Seems pretty clean! The last time I cleaned my sensor, I simply used a microfiber cloth (a new, dust-free one, of course) and it worked brilliant! Not sure whether I can recommend it though as it's pretty rough on the sensor.
