Strange anomalies in my photo

penev10

Can anyone identify if these weird marks on this photo are dirt on the sensor, chromatic aberrations etc?



I took another shot from a slightly different angle and they're not in it. Nor are they in any other shot I took that day.

Here's a close up:

Are they flying pigs ? that are moving really fast , and hence appear blurry .

How long was the shutter open for?

DaireQuinlan

Either midges/flies if they're relatively close to the lens, or swallows/swifts/sparrows or something similar otherwise. You've left the shutter open just long enough for them to become blurs on the exposure.

-edit-

Just from looking at the EXIF, 1/13th of a second is probably enough for this to occur all right.

Cheers. Never seen it before but this makes the most sense.

Strange things happen when you're in Amsterdam!

I'd agree with DaireQuinlan on this one.

Wikipedia has it covered:
http://en.wikipedia.org/wiki/Rod_(optics)

the fast passage before the camera of an insect flapping its wings has been shown to produce rodlike effects, due to motion blur, if the camera is shooting with relatively long exposure times

Pretty sure they are frankfurters in flight - a rare sight indeed.

My money is on insects too.

Chromatic Aberration is the coloured fringe you can see along the edge of objects:
