K-5 Oddity

Took about 250 shots at an outing a few days ago and a couple have problems that I can't figure out.The one with the blue spot on the white bird was much overexposed the one with the striped was panned.

You need to look at the metering mode and for large white subjects on a dark background you should be using spot metering. Otherwise you will not get the detail inthe white. This is not a K5 problem but an understanding of exposure problem that has existed ever since there was metering built into cameras

It would have helped if he had circled the problem areas. Take another look. He's talking about the massive blue section on the white bird which looks like it came from another image. I'm not sure where the problem areas are on the second image but I'm guessing it is the same sort of problem. As far as the problem goes, I suspect the memory card is faulty. I'd reformat the card, and if the problem shows up again, I'd replace it.

The blue area is the opening between the birds body og the wing, and you can see the blue sky and the wingtips. On the image it look unnatural. It´s because the white bird i overexposed, and that makes it difficult to distinguish between the wing and the body.

I can only see one bird in the photo of the white bird (Great Egret). The only blue spot I can see is the underside of the tail. The lacy feathers protruding beyond the tail are long, ornamental upper-tail coverts.

Ok thanks. In that case I'd love to hear from the OP exactly what problems he is seeing with the images and whether there are similarly composed images that don't have the same problems. Right now it is too much of a guessing game.

Kjelav found the area on the white bird that I thought was a problem but not so.Hope someone can explain where the lines on the heron came from.

Out of the 250 or so images taken I guess the one with the lines on the heron are the only one that seems to be a problem.

They look like electrical wires.

Yep - electrical wires...

By the way, nice pictures, but as was mentioned be careful about blown whites.

Also, you may need to clean your sensor (see attached image). Do another blue-sky test at home to see if it is repeatable. It could be an out-of-focus bug in the foreground.

Could also be droplet or dust bunny on the lens. Seems bigger and less symmetric than the sensor shmutz I seem to accumulate.
