Ansel, primarily associated with the great western photographer Ansel Adams, famed for his magnificent photographs of the Yosemite Valley, could make a creative artist-hero choice. For Adams it was a family name--he was named after his uncle, Ansel Easton. And, in turn, Adams was the namesake of young heartthrob Ansel Elgort, son of a photographer.
Derived from the same root as Anselm (another possibility), Ansel is a medieval Germanic name, whose meaning is somewhat unclear.
Ansel has been far from a unique name--it was on and off the popularity lists in the late nineteenth and early twentieth centuries, reaching as high as Number 540 in 1893.
