The Green Blob

What the heck is going on here? I took a picture in burst mode (three consecutive pictures taken at 3fps). The first picture has some weird green blog in it (click on either image to embiggen):

…and the very next shot, the green blob is gone…

DSC_2881

…thoughts? I was shooting with my 4 year old Nikon D70 with 18-70mm Nikkor Lens without a hood. Could it be an artifact from the sun over saturating the sensor?

  1. This is just me blindly hypothesizing with my limited knowledge of how SLR works… but is it possible for the mirror to have “stuck” or slowed down, causing an underexposed strip in the middle of the shutter release? It’s a vertical shot, right, so it couldn’t be the shutter itself; that would have left a horizontal underexposed line in the portrait orientation of the photo. Just a thought.

  2. I doubt it was the mirror because if it was, the line should be universal along the entire frame, not just a small section.

    The shutter does sweep left to right (or vice versa, I don’t remember which way I rotated the camera for this shot), however I would also expect the blob to be along the entire frame, not just the small section.
