Create an image of any subject using only ONE light source. Position the light source so the form and texture of the subject shows. Use the “Rule of Thirds” to compose your subject so it is not centered. Explore the interplay of highlights and shadows when using extremely directional light from a single source. A well lit landscape as on topic for this challenge. However, natural light spilling in from a window or door onto the primary subject can be very directional and dramatic.
Be creative. Use artificial light that you create or set up (candle, flashlight, etc) or natural light such as window light, one of the most beautiful forms of lighting in photography.
DO NOT USE YOUR ON-CAMERA FLASH FOR THIS ASSIGNMENT. You should be using another light source to light your images.

Using a single light source to show depth, form, texture and dimension. Following the Rule of Thirds to compose an interesting image.
