g'day my name is rod and i enjoy taking sunset pics from my front porch and as i took 1 particular pic i noticed thru my view finder on the camera that i had the green lights on indicating that the auto focus and flash were ready when a white light appear above these 2 lights.i pressed the shutter button and then looked to see what caused the white light.i could not see anything.i eventually downloaded the pics onto my PC. as i scrolled thru my pics i noticed a white dot. i enlarged it to reveal a whitish sphere. unfortunately i saved the enlargement without making a copy.this made me check all my sunset pics and found more "dots" that when enlarged revealed more of the same "dots".i simply don't know what these are.i realize there are reflections etc that can cause these but there is noting to reflect off.
