Have the students concentrate on a project concentration:
Portraits of one person indoors. Linda McCartney did these of her kids.
Landscapes looking out various windows at different times of day. Matisse
Still Lifes: antiques, flowers, studio - product photography (commercial),
still life's in motion a la Salvador Dali (Still Life - Fast Moving)
Shadows In Interior Settings
Experimental: Tungsten film used on an interior still life with outdoor
Colored shadows cast by colored water (wine) and rainbows created by
crystalware on a white tablecloth.
Hope this helps
