    Strange upside-down reflection???

    Ok I am asuming that this is a bounce off of the UV filter, but since I have never seen a reflectin quite like this I thought I'd ask around.

    This was taken at night in close to pitch black conditions @ ISO 200, 1/225, f4.0, with a 70-300mm lens set at 70mm. I used a flash gun for the strobe.

    The reflection is of the street sign, and slightly down and to the left of it.

    Got any clues?

    Exactly. If you were to separate the image of the ghost, then flip it upside down and reverse it left and right then it would be right on top of the actual sign in the shot. Film passes thru the camera this way (upside-down and inverted left-right) and digital sensors see this way too. It gets turned around the right way bouncing around inside the prism of an SLR viewfinder so you see it thru the camera with the correct orientation. You would see this upside-down and backwards world by looking thru the ground glass of a large format camera though.

    Here's an article about filter flare.

    Well I'm aware of all that. I just want to know how it got into the final image upside down. I have seen other such UV filter ghosts before in other cameras, but they were only mirrored, not upside-down.

    Thanks!

    Someone posted about this on Canon cameras before, and it was suggested it was reflection from the metering sensor.
    I haven't seen it on my 20D yet.

    Re: Strange upside-down reflection???

    I'm not sure that this all makes sense
    Sure we get an inverted image, but then ALL things should be inverted the same way.
    It appears that either the image here passed though without being inverted or reflected in such a way that it reached the film being inverted twice.
