Shoe-mount flashes offer an incredibly versatile, powerful and effective lighting solution (not to mention affordable)
Syl Arena, author of The Indispensible Speedliter’s Handbook (Peachpit Press, 2011), puts it well: To create interesting pictures, you need interesting light. And to create interesting light, you need interesting shadows.How do you create those shadows? By moving the flash off-camera. On-camera flash produces a coarse light that draws flat, shapeless subjects with harsh highlights and black shadows. Think snapshot.
