With my photography I want to bring the beauty of places and situations to the viewer. The lighting mood has crucial impact on each shot. I focus on capturing special lighting moods. Tiny differences in shooting and post-processing result in big difference in the final picture. Locations and buildings need special moods to capture the viewer's attention. Does the scene come into its own best in daylight or in the golden or blue hour? The weather, season, accessibility or visitor frequency can also be decisive factors. Based on these considerations, I determine a time frame that gives me a good probability of encountering the desired conditions.
For compositions that include celestial events, there is often only one day of the year when everything fits perfectly. For rare events such as a lunar eclipse, the planning is also done in reverse. If you know at what time the moon is at what altitude, you have to find a suitable subject that can be photographed at the right angle from a calculated distance.
Thanks to apps like Photo Pills or The Photographers Ephemeris, it's easy to determine when an object will be illuminated at the right angle with the desired position of the sun, so these calculations usually specify the time window for a shot.
