The Impact PortaFrame Scrim Kit is a portable light-modifying solution. Use the 24 × 36-inch frames and scrims to reduce, diffuse or block harsh lighting for balanced-looking images. The locking frames set up in seconds, using their 3/8-inch mounting pin with most grip heads (not included). Easily slip the scrims over the frames and you’re ready to alter the light falling on your subject. This can vastly improve your photos and reduce harsh contrast between light and dark areas that affect your exposure, leaving you with even tones and better pictures.
