    White squares in photos

    Hi,
    I recently noticed that my pictures have white squares in them. These squares are very small and only visible when the photos are viewed at their original size or bigger. Does anyone know what the white squares are? They all are perfect squares and they even have a black border around LOL .. They are in the same spots on all pictures. I tried 3 different lenses and the squares are still there so I guess it's the camera doing it, not the glass. Why is the camera doing it? It's driving me crazy. Any help will be greatly appreciated.
    Thanks

    If you google dead pixels, that's what I reckon

    Dust on the sensor is the only other thing, but, that's usually round

    I agree dead pixel. Not unusual. Depending on your camera, some have a menu item called 'pixel mapping', check your manual, follow the instructions, run it, and they should go away.

    Hi
    Thank you guys for the hints and advice... My camera is OLYMPUS E-420. It is not under warranty, unfortunately.
    I've done as told.. read about dead/stuck pixels - I think that's them.
    I've ran the pixel mapping function in my camera but it didn't help. I took more pictures, on different backgrounds, different shutter speeds and they're still there. I have 3 of them in total - on every picture in the same spot.
    As they say.. There's always something good in everything bad - it looks like I'll be getting E-5 when it finally comes out.
    Thanks guys a lot... Never before have I heard about dead/stuck pixels on the camera's sensor.

    at least they are easy to get rid of. Cause they appear in the same spot every time (as dead pixels do), just clone em out. Depending on your editing software, you can create an action to do it automatically (also depending on your skill level at editing and creating actions etc).

    pixels will die with age/heat. denser sensors like yours will be prone to more of these
    when you upgrade you may want to consider a 1.5x crop camera.
