1. Lighting is very important in photography, and so is styling.
Why not have students practice lighting and styling on food rather than on people doing portraits? Seems over done - portraits of people/peers? Perhaps it's classic and traditional though? (portraits). -Could save the project for an advanced class or for extra credit?
2. Also interesting topic - Styling. Talk about ways or "tricks" people use to stylize their subject before being photographed. What would examples be for food or fashion?
3. I like the topic of food, maybe it could be used as an allegory or metaphor. Students could draw a word/emotion out of a bag and choose to shoot a food in a certain way (with particular lighting and styling) to make that word/emotion come across. Their artistic choices would be very important and there would have to be a writing component to explain the thought process.
