It looks like the "golden hour" may be hardcoded as the hour before sunset. May I suggest updating it to be based on the sun's position in the sky?

In high-northern and low-southern latitudes, the sun can stay close to the horizon for long stretches of the day depending on the season. For example, in Iceland in parts of the spring and fall, the golden hour lasts for most of the day - amazing for photography and just enjoying the scenery.
