Etymology
Origin of photo1
First recorded in 1855–60; shortened form of photograph
Origin of photo-2
< Greek, combining form of phôs (genitive phōtós )
Explanation
Snap a picture with your camera and you get a photo, a recorded image made using light. To get a passport, driver's license, or school I.D., you need to have your photo taken. The word photo is short for photograph, a word whose Greek roots mean "written in light." It only took about 20 years after the invention of photographs for people to start using the colloquial (and quicker) photo. If you haven't visited a photo booth with your best friend, you really should; you'll leave with a strip of wonderfully silly photos of the two of you.
