Read this excerpt from “Eavesdropping” and answer the question. Just as, of course, it [getting my distance] was an initial step when, in my first journalism job, I stumbled onto making pictures with a camera. Frame, proportion, perspective, the values of light and shade, all are determined by the distance of the observing eye.

What is the figurative language used in the above excerpt and what comparison does it best create?

“it [getting my distance] was an initial step when”; it was the beginning
“it [getting my distance] was an initial step when . . . I stumbled”; making pictures was a mistake
“I stumbled onto making pictures”; discovered pictures accidentally
“I stumbled onto making pictures with a camera”; a camera was found
