Truth is, almost always these transparencies end up in the circular file. Here's an example though of a photograph that breaks the above rule. It breaks the rule against mid-day shooting because the subject matter itself is so arresting. As it is I had to enhance the image digitally somewhat by making the yellow stripe a bit brighter than it otherwise appeared. Still, this photograph would have been even stronger if the buttes of Monument Valley in the distance were illuminated by the rising or setting sun, or if the clouds in the distance had a bit more definition as a result of stronger side-lighting.
Early morning is in many ways more preferable for shooting than is sunset.
In the Southwest it is always a lot cooler then, and as well the air is frequently cleaner and clearer. In many locations early morning is also a time of ground mists. Even when the day is overcast these conditions can create a moody effect that enhances an otherwise mundane scene. Fifteen minutes after this picture was taken the sun burned off the mist and the scene because harsh and uninteresting. Fog, mist, rain or atmospheric haze.
