Race against the Sunset

Sometimes the sky just won't be ignored. I knew it was getting dark and I was losing the light. I had been taking pictures through the back roads of farm country on my way home. As I drove on the sky just kept screaming to get out and shoot this. So I did. The first few shots were fuzzy and dark until I realized my ISO was to low. It was a race against the sunset. My exposure was 1/3200 my f stop was 4. focal length was at 70. I had a canon EFS l series 70/200 mm lens. No filter. My camera was Canon T1i. The sun had set by the time I got all this figured out. But I still like the shot. What I learned that day was know my camera better to get the shot quicker. I don't do "AUTO" anything. The more I shoot the faster I get at the right exposure and f stop. I take my camera everywhere.
