What are they used for?

Camera bags and cases are used to protect your digital photography gear while traveling and for storage when not in use. Camera cases can be fitted for your specific camera or more general purpose and larger to fit a variety of digital camera equipment. Camera straps are used to secure your camera to your body, either around the neck or shoulder. There are hand straps that help you to hold a larger digital camera, such as an DSLR (digital SLR) more securely. There are cases available for your digital camera lenses, flashes and even for your camera memory modules.
