*What is a DSLR camera? DSLR stands for Digital Single-Lens Reflex. DSLR models typically offer interchangeable lenses, full manual controls, external flash units, and through-the-lens (TTL) viewfinders. They are usually large models and they closely resemble 35mm film cameras with handgrips and large lens housings. If you do not have a DSLR camera please consider taking the Point and Shoot Basic Course held at the Santa Barbara store.
