In this photography lighting workshop, recorded LIVE, Karl demonstrates how creating a matt-black box, or using a small black studio space, can enhance your lighting control and help you create powerful, memorable images.  If you work in a small studio space – especially a white one in which light bounce-back poses problems – this workshop will inspire you to try something different.   Karl begins by explaining the principles and benefits of the matt-black studio, before describing how he and the team built the black box for this shoot.  As he shoots a series of portraits, making subtle adjustments to his simple lighting setup as he works, Karl demonstrates how to control shadow density with awesome precision.  You’ll cover rim and edge lighting, controlling flare, using projection attachments, shooting portraits with shallow depth of field, and more.
