In this portrait photography class, Karl uses a Para 133 to create a bright, fresh image of model Markie Pearl. As. you’ll see, paras are great for portrait photography because they provide beautiful contoured lighting.  Here Karl explains each step of his four-light setup, including why it’s important to test each individual light.  You’ll learn how to balance multiple studio lights, control shadows and adjust your background tone through lighting ratios and position.
