The artist sees what others only catch a glimpse of.

For some, one the hardest decisions about choosing glasses is what to take as an elective. In University, electives are any class not related to your major. My major was Psychology, with a minor in Education. That left me with one opening for an elective. The struggle is choosing a subject a subject that doesn't require as much studying and work. You also want a subject far away from your major, yet one that also compliments it. I chose Theatre.
In high school, electives tend to be gym, the humanities or the arts. I didn't take art in high school, instead choosing music and drama. Although I thought they'd be easier, and fun, there was a lot of rehearsal time required, not to mention traveling to performances. There were times I wish I'd chosen art.
Now it's unlikely you'll find a nude model in a high school art class, but when it comes to University courses, or adult or community art classes, nude models are often part of the curriculum. Although not always, you often get models who are also students looking to earn some extra cash for school.
FH readers know I have a fascination about models who pose nude for art classes. In addition to featuring many visuals on the theme, I've also interviewed dozens of models who posed fully naked for a room full of clothed strangers. In addition to the CFNM/CMNM elements, there is something especially erotic about being the only nude person in the room.
As intense I envision the vulnerability to be, many of the models spoke of how much they enjoyed the experience. They also shared that although vulnerable and exposed, they also felt a power and control with being the center of attention. Since they must remain still, they have time to survey the room and as the students study every inch of their subject, the subject as well, studies those around them.
