Using gels during a photoshoot develops a specific mood. I used blue and red gels to create  contrast between the model's face. I adjusted my camera to a shutter speed of 1/100, an aperture of f5.6, and an ISO of 400. These setting helped the colors stand out even though the room was dark. It's interesting how using a gel can completely change the feel of a picture and make a simple portrait seem more complex.
