There's a specific time each evening when the light is perfect and everything has a beautiful golden glow. Right now it's about 7pm in my area (I'm sure that there's a similar golden time each morning, but I wouldn't know because I don't get up that early). I try to schedule all of my photo sessions to start at about 6:30pm so I can be sure to catch it. And I've been experimenting more lately with shooting toward the sun during this time of day. It definitely takes more thought in terms of settings and exposure, but can produce some really gorgeous results. I've been noticing some shots in our Flickr pool that clearly utilize this golden time of night, but I'd love to see more! Go experiment and show us your results.
