Title: How to add a band of blue sky to a croped panorama?
Post by: thierrylegros396 on August 15, 2014, 04:26:16 am
I've made a panorama with Hugin and some old photos taken without tripod.

It worked well (no junction or artefacts problems), but the top blue sky is cropped.

Of course I wanted to use Photoshop (CS5) to add a band of blue sky!

But how to do this seamless, because the blue is not perfectly uniform  ???

Hpe there are people that can help me  ;) ;)

Have a Nice Day.

An image would help to see the level of the problem you are facing and aid in offering suggestions for potential fixes

My first thought would be to try PS's content-aware fill.

Yes, it usually works very well for the sky unless you have branches/leaves and other fin details. In that case, you'll need to do some manual work.

Yes I have done it this way and it can work well. There is however the added crinkle that a natural sky appearance often requires that blue luminance be higher near the horizon and lesser as you reach the border of the sheet. To do that one would create two adjustment layers of differing blue tone and blend them using a gradient clipped to one of them.

Many Thanks to all.

No branches because photo taken at 3000m altitude in Saint-Moritz, so no trees present ;)

Will try that tip ASAP.

Have a Nice Day.

Far from perfect but satisfies me  ;) ;) ;)

Hi Thierry,

It's not bad - I think a bit of adjustment of the gradient to make the transition a bit smoother would make it better, but you've got the basic fix there.
