Hey Vincèn,

That's a great pano ... and what an excellent day for skiing ! ;)

I like this one even more: Forest slope Crêt Granier at 7 Laux

Keep up the good work.

Nice action shot, great exposure and colours.

I noticed a small blending error at zenith in this panorama and a strange darker area in most of your other blue sky panoramas, at zenith ... and always opposite to the sun. It could be a vignetting problem. Are you shooting 6+6, no zenith ?

hum strange but by looking more in details I noticed what you talk about, it looks like I'm not looking enough zenith and sky :mrgreen: In fact I'm shooting at 24mm so 3 rows of 10 shots plus zenith plus 2 nadir :) I'll look more into that to correct it :)

Thanks,

You're welcome.

It might be a blending problem. Change your default blender and see if things get better.

Good point, looks like Bicubic softer blending is better than Lanczos 1024 I was using previously :) What do you think of sky that time ? looks better in my mind :)

Hi,

Bicubic and Lanczos are the interpolators used by PTGui when the image is remapped to the desired projection, but I was referring to the blending algorithm you used, as in: PTGui's own blender, Smartblend or Enblend.

Install Smartblend or Enblend and try to see if they make a difference.

Are you using by any chance a polarising filter on you lens ?

Your image should look more like this:

... with a nice blue gradient, instead of that darker area opposite to the sun, when you look up.
