What caused this?

Hi Folks

This is a sun set photo converted to black and white. I tried to burn the mid tones in the sky along the upper right toward the middle using a big soft edge brush at 3%. It left a herring bone sort of pattern that wasn't in the clouds. Moving the brush at different speeds didn't make any difference. Any one out there think they know what happened?

Thanks

Cannot really say I see what you are seeing. Not a bad image, looks as if you were shooting into the light, its kind of dark too. I cannot see what is in the shadows but it looks like a mountain range. I might try taking this again in the morning, with a cooperative sky of course. It looks like it was taken in the evening, is that right?

Can you circle the pattern you are talking about - I'm not sure I see where it is.

It COULD be that the image is just 30k and what you are seeing is pixilization. Is the pattern the same on your hi res image?

Here is a larger sample. It's fairly hard to see at this file size but if you tilt your head, squint with one eye and stick your tongue out its noticable. You're right jjeling I was shooting into the sun set with out a ND filter so I had issues without trying HDR. Which raises another question. If you can only buy 1 ND filter which would it be for shooting sun sets, ND, ND grad, light , medium or dark?

Thanks again folks
