Photography Tips : Lighting is paramount since it dictates the shape, texture, contrast, and shadows in your images. The golden hour is about a one-hour window briefly after sunrise or before sunset.
The longer shadows and especially the more diffused light during these periods provide much more flattering light. Since the light is diffused, you’re much less likely to ‘blow out’ highlights or lose detail in the shadows that are difficult to avoid during the strong light available during most of the day.
