Re: Unusual Red Glow Over Minnesota (2009 February 17)

Hey TRL.

Unless you were photographing that pretty view of the sun illuminating the underside of clouds with a piece of glass or other reflecting material or fog in front of your lens, I doubt very much that any sort of auto focusing beam contributed to the color or realism of that picture.

Re: Unusual Red Glow Over Minnesota (2009 February 17)

Does it fire this light when the flash isn't on? I don't think I've seen any cameras (including my own Powershot) that use the autofocus as...

Re: Unusual Red Glow Over Minnesota (2009 February 17)

Hello. I think that glarysun got it right. I had also used google-earth to get exactly the same apparent altitute, orientation and angle as the photograph. After comparing the google-earth view with the APOD photograph (using Alt-Tab to go back and forth like a primitive blink-comparator), it seems ...
