Here's an image that I processed from 5 images. The images were processed in raw using sync.

Anyone know why there are "lines" in the sky??

nope but you can remove it with a blur tool

Looks like a very thin layer of clouds that are reflecting the sunset. Nice photos. Thanks

Since this from a series of 5 pictures, do you see any clues in the under exposed side of the series? Check also the over exposed, just in case.
HDR software can create bands like that but they need a starting point. Find it and you will find your explanation.

On RAW HDR, why 5 shots? You can get away with only three as each needs only to be 2 stops over lapped...
12.34.56 Under
    12.34.56 Correct
        12.34.56 Over
This gives you 10 stop HDR when a JPG would give you only 3!!!

My guess would be wrong white balance setting....

Should have been:
12.34.56 Under
          12.34.56 Correct
                    12.34.56 Over
And a result of 14 stops vs 10, Sorry

If there were clouds, then there ya go. I've had some (what I believe is called) banding in my images. Back off on some of the adjustment parameters (for which I cannot remember which at the moment, plus I don't know what sync is). Try a do over and tone down some (perhaps contrast/saturation) settings.

Several thoughts. Were you using a polarizing filter, in the HDR software did you see this while processing? I have had similar problems, mostly while using a polarizer but also not being sure what I was doing in the HDR program. I suggest you contact the help at the software developer and see if they can help you through the correct process.

Could you please explain the 12.34.56? Thanks, Mike

RAW is capable of 5 to 6 f-stop dynamic range.
1 is the first 2 the second 3....
The ',' separation is to show the comparative with JPG dynamic capability.
Sorry, I did not make that clear.
If your camera cannot bracket 4 stops at the time, bracket at 2 and kill the intermediaries shots. ONLY FOR RAW.

Actually, it looks like the vapor from a decaying contrail.

Could be. I didn't like it so I muted it with the healing tool.
Here's the revised image-

Now you just need to fix the edges and you are good to go!

Are you referring to the lighter colors around the right side? I didn't do any adjustments there. Appears as if it's from polarization. What do you think? All of the raw images have that tone.
