I am shooting in plain blue skies with no clouds, constant exposure, but get sky streaks of dark or weird color at the edges of the subframes.
I find they are almost entirely gone if I combine in simple/linear, but then there is ghosting.
If I choose anti-ghosting the panorama is much sharper but the sky has streaks.
So I am going to use anti-ghosting to make the land, and overlay the sky from a simple combine on top. Is this making more work than is needed? Can I get anti-ghosting with no sky streaks by changing some settings?
The panos almost always have perfect beautiful skies when in the Autopano app, it's only the rendered product with the sky streaks. I assume this is because the app uses a simple combine for display?
thanks
Mike

how do you take your Images? Auto WB? anithing other not in Manual mode?
it can be vignetting from your lens & f-stop used.
which autopano Version do you use? pro/giga/1.x/2.x/3.x?
some screenshots would help too...

Hello, thanks for your post.
1) I will look at my WB settings and validate everything was constant. Even if I am on AWB, I force all frames to "shade" or "daylight" when doing the conversions.
2) I am using Autopano Giga x64 3.0.5
3) Can Autopano Giga parse the EOS 6D raw files and force them all to a single WB?
4) I am using EF 300 f/2.8 lens at f/5.6 vignetting should be neglible, I think.
Here is one of my better results so far

Hmmm i cannot post attachment images in here of the difficulty?

Hi
You will see vignetting in clear sky up to f/16 if not corrected, even with a 600mm!
Try it out and take a single image with clear sky. Copy the corner and move it to the middle.
You will be surprisingly!
APG isn't able to correct vignetting at the moment, so you have to do it first with other software.
Btw: If I load "Mount Denali" in iE 9, I only see a small vertical strip.
With firefox, it's ok.

OK thanks for pointing out the issue with IE. Also, I did find out yesterday that my problems are on most vignetted series at f/4.
f/5.6 is definitely a bit better but vignetting correction is needed on all as you say.
I am still getting odd color differences between frames even though everything is being set constant. Is there easy software for saying... make this sky the exact same color as this image sky.... (Photoshop match color?)

Yes --- Photoshop 
Did you shoot in the sun direction without sunshade ?

Actually the Sun wasn't up yet in the most troublesome series, but the shots ranged from 90 degrees away from the Sun to quite closer.
