UFO or ……… ?


Recommended Posts

John,

 

Flare is a product of the lens, not the camera body. Many times it is exacerbated by the use of one (or more) filters (UV, Polarizer, etc). You can find lots of information on lens flare in a google search.

 

(As an aside, it is possible for a digital camera sensor to reflect light back into the lens causing flare, but in this case the flare is caused by the lens itself.)

This is NOT flare! This is a reflection of the micro-pendulum tool used inside the camera to determine its orientation: When the RED line is over the pendulum the camera is in portrait orientation. When the RED line is under the pendulum the camera is in landscape orientation.

Thanks Jim and all.

 

"But this is flare. Possibly exacerbated by by a reflection from the image sensor. Digital's do that, you know."

 

What does the sensor look like under the lens. It starts with a glass protective cover? Right? How thick and optical characteristics? Then what about the anti-aliasing filter that can be removed on some high end cameras? Anything over the physical pixel? Would really like to know everything that's happening inside the box. Regards.

Seriously, I venture this guess.

 

This is not really 'traditional' flare as we know it. We can observe the following:

 

1) the flare-like image is perfectly centered

 

2) it's made of the three primary color (R/G/B)

 

3) it is shaped exactly as it would be if you had shone a beam of light from the rear of a lens.

 

Thus, we can safely deduct that it was light reflected back onto the rear element (causing the R/G/B separation which here appears in reverse order of course) recorded by the sensor.
