    Question Strange effect

    OK experts, any ideas on a strange effect in this shot, taken with my A200 & Tamron 70-300?



    (Large size to get the detail of the issue to stand out.)

    Note on the trombone players' face, collar, and shoulder to some extent, the radial dark, shadow like lines that weren't really there.

    They don't extend across the trombone, don't extend to the white glove, or onto the silver trim on the hat.

    They seem to be some short of reflective effect from some point toward the right side of the shot. Can this all be off the curvature of the back end of the trombone? I've never seen anything quite like this, and obviously didn't recreate it.

    Based on the direction of the sun ... and that polished curved chrome ... yeah, you have a decent reflection going. As long as there is a shadow
    (less lighted) surface to reflect it to ... viola, the reflection is projected to the nearest surface.

    You will often get these kinds of things from flash shots, too, when you snap an image of a reflective surface (e.g., glass, a mirror, shiny objects).
    Usually you have to "touch" them out.

    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.

    I think it's just a reflection from either the trombone or somewhere on the outfit.

    I've seen that before in an image that I took. It is just the sun reflecting off of the trombone.

    Light vs. dark

    I've seen unexplained (except by reflection) light spots, streaks, and etc., where extra reflected light made bright spots. On sunny days like that, with bright objects, I've had a lot of shots wash out. Especially when circumstances prevent being able to get an advantageous position, relative to the sun.

    It was the dark streaks that were somehow robbed of light without the benefit of an actual shadow that was a surprise.
