Shooting with color gels allows you to get amazing creative effects that big studios use to add depth to skin tones and cinematic light to your shots. The kit comes with Rose Pink, Yellow, and Peacock Blue color gels that attach magnetically to the C1 Plus. You can stack different color gels to make new colors. Stack the blue and yellow for green and the pink and yellow for orange. Each gel gives a different effect, keeping your subject from looking washed out or giving your shot a moody sunset vibe.
