Funny story about these bottle caps. I went to this grocery store in my town, and they had coke in glass bottles! I love glass, especially glass soda bottles, cause they're old school. Anyway, I buy three bottles and leave. It turns out, the Coke is mexican. That's right. Mexican. The writing on the label was all in spanish, and it said "Hecho en México" which means "Made in Mexico"
On to the fun stuff. For this photo, I stacked the caps onto a plain white piece of paper, so there would be no distracting backgrounds. Plus, it brings our the white in the letters, and makes the red of the cap really pop. I used my desk lamp for the dramatic shadows and highlights, however I turned my flash off and as such it was a little dark, so I artificially increased the exposure level. I don't like to do that, usually, but it looks 100 times better now. I also manually focused, because the auto focus on my camera doesn't like macro shots xD
