As you progress with your photography you may find it necessary to use more advanced equipment. Perhaps you’re struggling to ensure perfectly colour accurate images, capture greater depth of field, or create tiny, controllable patches of light…  Having worked as a commercial photographer for 20+ years, Karl shares some of the specialist kit he, and other professional photographers, often use for product shoots.  In this class, Karl discusses these various bits of equipment and why they’re useful. He also explains some budget alternatives to some of the gear shown in this tutorial.
