This image is from the July page of my 2018 calender. It’s the center part of a larger panorama. The projection is rectilinear. I used a neutral density filter with 10 f-stops to get an exposure time of 8 seconds.

Recently I got a question about this panorama I published on Maps Views:
Here I try to explain the problem. In short: I’ve just been too lazy to make an “up” shot (zenith). It is completely missing. The stitching result has not been retouched at all.
When making a horizontal pole shot the “zenith” and “nadir” end up near the equator of the photo sphere. You can see this clearly in the image below, where the red image borders cross. “Zenith” and “nadir” in this case means the direction where the pole is pointing!
When removing all images but one, this looks like the image below. You can clearly see, that the worst part of the fish eye lens ends up in an area of interest. In this case the right side of the river bank.
This image shows the original fish eye shot. You see the bad part of the lens ending up on the right hand side of the river bank.
The solution to this problem is easy: You just need to take an “up” shot. However in this case “up” is again in the direction of the pole! Unfortunately for minimizing the parallax problems I would have needed a different mounting option for my camera.
This image is a panoramic image in rectilinear projection. It’s stitched from 3 images in landscape orientation. Each of the images was taken with a neutral density filter (10 f-stops) to get an exposure time of 15 seconds.
This year I entered some images for the Epson International Pano Awards. In the fourth year of the competition I was awarded with two silver awards. All the other images were awarded with a bronze award.
The first silver award was assigned for the following reprojection of this spherical panorama. It reached the 40th place in the category ‘The Built Environment – Open Award‘.
The second silver award was assigned to the following image. It reached the 11th place in the category ‘Nature – Amateur Award‘.

We hadn’t visited the mountain Herðubreið but we went back to Germany with the plane Herðubreið 😉
A short stop at Strandarkirkja and the blue lagoon before we spent our final night in Kevlavík.
Today we visited a lava field of the vulcano Hekla and we had a great dinner 😉
