In the moist and warm summer evening, the old AGA lighthouse on the western tip of the small island of Ådkobb is waiting for work during the night, guarding the waterway. Toward the west and the sunset, the clouds remain disappearing August thunderstorms over the inland Östergötland in Sweden.
Lighthouses like this are rare today due to the expensive service needed in the summer each year. The gas supply had to be changed to new gas cylinders, as well as checking the the the Dalén burner giving the light its blinking character. You can see the larger Fresnel lens in the photograph, with the smaller sun valve on top to the right. The valve turned the light on in the evening and off when the sun came up.
Today, many AGA lighthouses are equipped with LED lights, driven by batteries charged by solar cells.

Interesting facts

The picture was taken on infrared bl&w neg film. A black filter was used in front of the lens, only letting through the infrared wavelengths. In nature, chlorophyll reflects this light to protect the plant from heat, making leaves and grass white in the photographs. Only dust and moisture reflect the light in the sky, making clear skies appear dark. This photograph shows a quite crowded atmosphere. As you move the camera toward the backlight, the sky will become lighter as you get closer to the sun. The infrared light will increase in intensity.

Kodak bl&w Infrared High-Speed Film 2484 (now discontinued) with a Kodak Wratten black filter nr. 87. The film hand developed by the photographer. Negative scanned 2020, adjusted, balanced, and retouched from scratches and dust in Adobe Lightroom and Photoshop, preparing it for Fine Art prints.
