Readers tackled this week's Mashable Photo Challenge Guest Series with incredible artistic talent.
We saw a great mix of black-and-white images and vibrantly colorful photos, all featuring strong uses of shadow. Guest curator Victor Bezrukov, a photographer based in Israel, selected his favorite 16 from the submissions.
"It was a very difficult task to choose the best photos," he said. "Thank you, submitters, for all your fantastic work!"
