This is the sunset that occurs closest to the Autumn equinox, which is the point in the year when the sun crosses the celestial equator heading southward, marking the transition from summer to fall. This event results in equal lengths of day and night, creating a unique and balanced twilight experience.
But with so many trees around, the experience is limited to a narrow field of view towards the sunset. Nevertheless, the experience remains wonderful.
This panorama is the September 2024 Equinox contribution for the 'September Wrinkle' event of WorldWidePanorama.
Automated control points arenât an option here because the individual images are predominantly black:
There are 6 pictures taken every 60°, including Zenit and Nadir (6+Z+N). To establish the control points, the brightness in PTGui was increased by +5EV.
Without precise control points, a 360°x180° panorama can become warped and distorted. It might seem that creating panoramas with large areas of uniform dark color would be easier, but unfortunately, there are no shortcuts in this process. Accurate control points are essential for maintaining the integrity of the image.
My Nikon F2 has a battery cap that can be opened or closed using a coin.
To avoid scratching the cap using a coin or any other metal shaped object, I want to fabricate a plastic tool specifically designed for this purpose. This tool would allow me to open and close the cap without causing any scratches.
The only measurable aspects of the slot are its length and depth (a is half length, b is depth).
However, I need the radius: r=f(a,b)
The radius r and side a form a right-angled triangle:
The hypotenuse (longest side) is also r, so c = r - b.
Using the Pythagorean theorem:
All this gets a radius r of 22,9mm.
Machined from a 50mm plastic round stock on the lathe, the middle ridge has precisely the calculated diameter of 45.8mm.
Das Snoqualmie Falls Wasserkraftwerk besteht aus zwei Kraftwerken mit einer kombinierten KapazitĂ€t von 53,9 MW. Es entnimmt Wasser aus einem Stausee oberhalb der WasserfĂ€lle, um saubere Wasserkraft fĂŒr etwa 40.000 Haushalte in der NĂ€he von Seattle zu erzeugen. ZusĂ€tzlich hat das Kraftwerk historische Bedeutung und bietet öffentliche Parks und Wanderwege entlang des Snoqualmie River.

The Snoqualmie Falls Hydroelectric Plant comprises two powerhouses with a combined capacity of 53.9 MW. It draws water from a reservoir above the falls to produce clean hydropower for approximately 40,000 homes near Seattle. Additionally, the plant holds historical significance and provides public parks and trails along the Snoqualmie River.

FrĂŒh morgens waren schon viele Leute unterwegs. Damit mir niemand die Sicht versperrt hat, habe ich bei den einzelnen Bildern immmer auf den richtigen Moment gewartet.
Es war sehr sonnig an diesem Tag, und natĂŒrlich sind die Schatten bei hellem Sonnenlicht ausgeprĂ€gter. Um den Schatten der Kamera am GelĂ€nder zu entfernen, habe ich zusĂ€tzliche Bilder von dem GelĂ€nder und der Plattform aus gröĂerer Entfernung gemacht.
Diese Bilder wurden dem Projekt als zusĂ€tzliche Bilder hinzugefĂŒgt, fĂŒr die Brennweite optimiert und entsprechend maskiert, um die Schatten so gut wie möglich zu ersetzen.
Behind the scenes
While it was early in the morning, there were already a lot of people around. When taking the individual pictures, I waited for time gaps in order to have as few people blocking the view as possible from the railing.
It was very sunny that day, and of course shadows are more pronounced in bright sunlight. To remove the cast from the nodal adapter and the camera on the railing, I took additional pictures of the railing and platform handheld from a larger distance.
Those pictures were added as additional images to the project, optimized for focal length, and masked accordingly to replace the shadows as best as possible.
