Photography tips
How this image was taken
This shot uses an aperture of f/2 and an ISO of 1600 to capture enough light for the night scene during the two-second exposure. The 12 mm focal length provides a wide angle that combines the hotel with the sky.
- Choose an aperture that is as wide as possible to achieve sufficient brightness in challenging light conditions.
- Use a short focal length to capture extensive structures like the mountain massif completely.
- Adjust the ISO value so that enough details remain visible in the image during short exposure times.
