What do you think

What do you think caused the bright spot where the moon just went behind the cloud (upper right) to look like feathers. This is a 30 second exposure. Not a great image but the feathers caught my eye.

Spoke with a photographer friend that was out with me when I captured this. He had similar results with his 30 second exposures. The clouds where moving quickly parallel to the ground. I know it's a crappy image. Just wondering if anybody has seen the same effect/light. M

I've never had it happen to me but I was going to say fast moving clouds

Cool -- I too think you caught it long enough to catch the bright light off of the moon. Normally you'd see the whole moon shinning like that if it were a clear night. The moving clouds helps with the displaying of the light.

I'd wouldn't say it's crappy at all. To me I really like it. Something different and something wonderful at the same time

I could hazard a guess but Mr. Cowley of Atmospheric Optics, if asked,
might provide you with a more critical complete answer.

I was looking for the clouds to smear. This is a borrowed 24mm f2.8. The first time I used it, to my eye f8 seemed pretty sharp edge to edge. This was the second time using it and at night. That appearance of sharpness is what caught my eye. It appears only part of the image is in focus. I know movement is the major factor, so the other part is the direct light of the moon. Like catching moonbeams. I wonder if it can be duplicated or improved? Thanks for the comments and the link will check it out. M
