    I shot some fireworks for fun the other night and all my pictures have the same spots on them. I am just wondering what it is. I think it is dust, but where is it coming from? I have a D100.
    What is the best and cheapest way to fix it!

    Spots on pictures = glass or sensor dust... If its on the lens, clear the front and back with lint free micro fiber and lens cleaner (get from photo store)...

    If its on the sensor i recommend getting it professionally cleaned, dont want to break anything by doing it yourself.

    Probably dust on the sensor, that is if it is in the same spot all the time. Try cleaning the sensory (with extreme caution) assuming you know what you are doing.

    Post some pictures please, Spots of all shapes and sizes can result during fireworks. In order to accurately tell you what they are we need to see them.

    Post a couple of the pix. If the dots remain in the same position, they are certainly from dust on the sensor. NEVER use canned compressed air to clean it. You can try carefully using a good quality bulb, but you must be careful of mirror, shutter, etc. If that doesn't work, get it cleaned (my photo shop charges $45). Replacing a sensor is VERY expensive -- be careful.

    they are there!
    How do you post pictures directly to the thread? A bigger picture will show the spots better.

    I see them, What causes this is pixels giving out during long exposures. It happens on cameras that do not have internal noise reduction. Your sensor and lens are not dirty, this is a short comming in the equipment.

    You need an Image file url. Flickr has that multiple size dealie thing that makes it inappropriate to just copy past the url into image tags. You can retrieve this by right clicking and copying the location, then wraping it with img tags

    Thank you! My other pictures in all other conditions didn't have these spots. Didn't think about the long exposure. It was my first time playing around with these longer exposures.
