I've gotten my share of top-tier photos before...but they're often needles in the warehouse-of-haystacks kinda things. Good equipment helps, of course.
There's a story from my college that touches on the difference between professional and amateur. In 1976, The American Pavillion for the 1967 Montreal World Fair caught fire and burned spectacularly...becomming totally engulfed in flames for several minutes and looking like a stationary ball of fire. Across the river, no more than 3kms away and with an unobstructed view, the photo-class was walking through the library with their cameras in hand and loaded. 40 students, 40 cameras, 880 potential shots.
Not one single picture was taken by the students. The teacher finished off two rolls before it was done. It's the teacher's favorite story to explain about how a photographer always has to be ready.
BEFORE:
This is what the pavillion looks like now. It used to be covered with some fabric.
