To check sun rise and sun set is a useful routine for photographers. I downloaded an app years ago. It’s called ‘Blaue Stunde’. Where ever I am I can check the blue hour, the golden hour, when the sun sets and when the sun rises. I also learn about the length of the day. Right now we have 9 hours and 22 minutes day light.
Sun rise and sun set can structure a day. We became so independent from the rhythm of the sun as we have electric light sources nowadays. Yet for those who are interested in light sun rise and sun set becomes interesting again.
