Evaluate the pic : got a black spot in sun

[mik0930]

The picture was taken last Holy Week: April 13, 2006 while in a ferry ride from Samal to Davao (both in Philippines). I took the photo and noticed a black spot in both pictures. Can anyone explain the spot. Anyway, it was took about 4:50PM, the last ferry going to Davao.

Well, yes it was.

And, having been created within three minutes of the other thread back on Sept 23, it would have died a quiet death then and there - if you hadn't bumped it back up.
