"Swirls" in the background
Sep 16, 2014 20:44:37 #
Can someone please tell me what causes the "swirls" in the background of this photo and how to avoid them if possible? I shoot in raw and use PSE11 for PP.

if that isn't a stacked image i would say the lens has 'poor' bokeh.

That is banding likely caused by something you did in photo element.
Check you PM, please

Those are Jpeg compression artifacts. When you save your image you may have your jpeg settings set to low quality. Check your jpeg save settings.
I posted some high quality (low compression) and low quality (high compression) photos to demonstrate

stupid me, i assumed he would have checked to see if it had banding/halo before he peed on it.

Thank you all for your responses, I believe I did set the Jpeg to low quality. I will check tomorrow.

That's called posterization.
It happens when a nice gradual fade from one color to another is redefined in fewer colors/shades.
It can make for an amazingly beautiful effect, but really sucks when you aren't looking for it.

"see if it had banding/halo before he peed on it" is a bit of a distant relative too!

Banding is such a constant threat when stacking images that we tend to shy away from any shading/fading in our images or add it after the stack is completed.
Still, there are those rare occasions when the swoops and swirls can enhance or frame a subject.
And i'm sure every one of us has used compression of the dynamic range in order to obtain a little pseudo sharpening of an otherwise soft image.
Perhaps even going so far as nudging that contrast slider on occasion.?

Those bands are usually the result of low resolution, whether your jpeg compression is set wrong or you are just shooting at too low resolution setting in the camera. Either way, the camera isn't capturing enough information to blend the colors in the background of the photo. It is more apparent in the soft out of focus areas of a photo because, as for instance with your frog, it is sharply focused and there are details in that area of the pic that tend to mask the effect you are getting in the background.
