OK, I have to admit that early morning light does make a difference. I have relied on mid-day shots for most of my pictures including many that have been entered and won competitions. This is primarily due to the time that I have been at a place in my travels, but it is also due to an aversion to getting up extremely early. My recent Xeriscape and Wilson's Creek pictures have convinced me to look more at that early morning light.
What about you? Do you mainly take pictures during the "Golden Hours" of early morning or late evening or do you just shoot when you want? Let me know...I am curious.
