Creating a panorama can often lead to uncovered areas. For example a panorama created from these pictures (Seattle Waterfront Park Project):

The stitched panorama has uncovered areas. It is not a perfect rectangular area:

Using the fill hole option in the PTGui editor blends in those areas:

This is the cropped panorama without the fill hole option:

And with the option to fill holes, more of the original areas of the image are preserved:

The Laowa 4mm f/2.8 is a manual focus Circular Fisheye lens for APS-C cameras.

Best setting for 360°×180° Panoramas is at the beginning of the infinity mark and f/5.6. This puts everything from near to infinity in focus:

The 4mm Circular Fisheye lens allows you to capture stunning and unique shots:

Interactive Panorama Laowa 4mm

On a sunny day, position yourself so that your shadow falls within the area of overlap (your shadow is perpendicular to the direction you are looking):

The overlap with the lens's 210° field of view at the seam is large enough to cover the shadow. Even for a nodal point adapter with a small footprint.
This is not possible with a 180° Fisheye.

With the lens at a height of 1.6m, the 30° overlap is 1.6m*2*tan(15°)=0.85m (2ft 9").

Shadow covered:

It is common for fisheye lenses to have decreased image quality toward the edges, but not really an issue if it is only used for web/social media. The ordinary Tiktok brain doesn't recognize this deficiency anyway.
The two images were taken without a tripod, so the stitch doesn't result in everything perfectly vertical and also has some minor misalignments. And with only two images, there is not much to vary. A nodal point adapter is recommended.

And there are internal reflections at the edges with bright sun light:

Und um die Tiefenschärfe zu erhöhen, wird das Focus-Stacking angewendet, siehe Combine pictures with PTGui, Focus stacking

Mehrere Bilder werden mit verschiedenen Fokussierungspunkten aufgenommen und kombiniert.

In PTGui werden die Masken mit den fokussierten Bereichen gemalt und dann kombiniert.
