I had never done a photo shoot that required me to get up at 3:30 AM so it was high time I organized one. The idea was to get to the location as the sun rose. While the sky remained cloudy throughout the morning, I really don't regret heading out that early as we still ended up getting really wonderful pictures.
While I hate getting up early in the morning, the forest looked so beautiful and calm at that time and I think it really came through in the images. 10 out of 10 - would go again.
