The audience for this video would be mostly 18-year old high school graduates.
Wow! I hadn't realised the "kids" might be 18. In any secondary school in the U.K.(about 11yr olds to 16 yr olds) this use of the word "kids" would have lost the audience at about 12 year old maximum. University students start at 18 and to all intents and purposes an 18 yr old is an adult in the U.K.
My mother still refers to 57 year old me as one of her "kids".
“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”
