Back light is popular for creating drama and makes for good silhouettes. Indirect backlight can add depth and dimension to an image. Drama lives here, but we need to be careful with exposure to avoid overexposing the light source, a blown out sun never looks good, meter carefully to expose for the highlights.
Like any other light source, backlight can be direct, indirect, or diffuse.
