El Jem (Thysdrus) Amphitheater, Tunisia

360°, Pocket APN, no tripod, ...

Whole pic is 11302 x 1450 pixels (click for full size)

Image

Note some problem on center area, with the metalic grid on the floor as well as color auto adjustments that are not done on a 360° basis.

And oh, there are some real ghosts too ! ;-) 100% crop :

That's right, Autopano Pro did not detect this panorama as a full 360°. Maybe you can try with higher (maximum) settings for detectivity.

To my eyes, overlap between the max-left and the max-right images is less than 20%, and some subjects have moved.
That's why it did not succeed with default settings.

Even if APP cant's find the full stich, you can greatly improve the color correction result. Set a hard anchor on 3 correctly exposed images: one left, one center, one right. Set all others in "white balance + transfert" mode. Results should be great ;) If you still get color deviations, set other photos in "Transfer function" only.

Now, i'm interested in results :)

That's a typical ghost from moving subjects and multiband blend.

There is already the option of the multi-layered psd output, that allow to mask manualy ghosts in order to get a perfect result.

Antighost blend is planned, it will allows incredible results even with low quality sources !

Where can it be done ?

I've used the Panorama built'in APN function to achieve minimal overlap. But yes, subjects have moved :)

Ok; I'm having a try :)

You can change the settings for the whole application in the options, or change for this only group (icon with a hammer)
Higher settings will give more tolerance with small overlaps.

Small overlap is the main difficulty of these sources. Sure, 80% overlap is overkill, but min. 30% is great for accuracy of the geometric and color corrections.

Cool :)

PS : multi-layer output is editable in Gimp too.

Here is it (click for full view):

Now, color reflects the right luminosity (witch has changed from one side to other, because of wind and clouds). For comparison, the old one :

Nice !
Color and contrasts are far better like that.

With some experience you'll quickly find how to get the proper exposure from your shots.
That's like learning to take better shots with a new camera. It takes some times and trials ;)
