The “golden hour” is generally defined as the hour of sunlight just before sunset. It is particularly conducive to natural light portraiture, though other things, including landscapes and cityscapes, look better in this light, too.
I also think that there is a golden hour in the morning. But to catch it on a summer morning in South Dakota means being out sometime around 4:30 am, which is not exactly “golden” for most portrait subjects. But I will say that Lonesome Lake, where I took this photo, is flattered by this light. Even my 59 year old face might have been improved by the soft cloud and fog filtered light present on this morning. 🙂
