Sunny Sunday afternoon at the Kirkland Piers.

Hidden, but in plain sight. This pier is next to the popular Marina park, but since the entrance is hidden behind the street, it was empty.
The long shadow (picture #4 in the index) was covered by taking a nadir picture (picture #8 in the index) off center. Almost. One piece of the shadow is still visible at the siding of the pier.

This panorama is the 2025 spring contribution for the event 'hidden' of WorldWidePanorama.

Die Herstellung

Focus stacking involves taking multiple photos at different focus points and merging them into a single image that contains only the sharpest areas.

Three images, each focused on different points -foreground, middle ground, and background- were taken and subsequently merged using PTGui and HeliconFocus.

PTGui

PTGui automatically established control points and precisely aligned all the images, performing as expected for a panoramic image application. Using a simple mask, the three in-focus areas were seamlessly integrated.

HeliconFocus

Since all the images were taken handheld, there are slight variations in perspective. This is evident in the results from HeliconFocus. It is likely that a dedicated focus stacking application expects images to be captured using a tripod for optimal results.

Is it not surprising how well a panorama stitching app performs compared to a dedicated focus stacking app?

I took this panorama about an hour before sunset without a tripod while waiting at the main exit. The main challenge was aligning the pathway with the building's geometric facade.
Taking more pictures than necessary helps with panoramas because it allows for better adjustments and alignment.
Using the mask feature in PTGui is another significant advantage. It allows you to force the seamlines into less prominent areas, thereby minimizing visible overlaps and reducing poor alignment.

Only the central parts of the images were used, which minimized errors. Note the nearly uniform size of the horizontal image parts, with the exception of the pair on the left side of the large building.

At one point, I had this rare PTGui result:
