How Daylight Varies
Golden Hour Photography

No Brasil

O Brasil está majoritariamente nos trópicos — a variação entre verão e inverno é menor que em latitudes altas. SP: 5h30-18h45 no verão, 6h30-17h30 no inverno. Porto Alegre: 5h10-19h20 verão, 7h00-17h20 inverno (maior variação por ser mais ao sul). A "hora dourada" para foto: 30-60 min após nascer e antes do pôr.

Usos

Fotografia, trilhas (calcule horas de luz), energia solar (horas de sol direto), pesca.

⚡ CalcWolf Insight

Landscape photographers call the 20 minutes around sunrise/sunset the "magic minutes" — when the sky can turn vivid pink, orange, and purple. Being set up and ready 30 minutes before sunrise is the difference between capturing a spectacular shot and missing it. This calculator helps you plan exactly when to arrive.
