The 3 variables of photography are: Camera Angle, Lighting, and Proximity.
#1 Camera Angle
Camera angle is very important when taking picture. Camera angle is the angle at which the camera is pointed at the subject. A picture can be taken in many different angles such as: Eye level, above subject, below subject and not squared or slanted. When the camera is at eye level, it's normal because we see things at eye level. When the camera is above subject it makes us feel like we are looking down at the subject. Makes the viewer feel bigger and the subject smaller than it is. When taking a picture below subject, makes the viewer feel smaller, and the subject larger. If the camera is not squared, it makes the picture look uneven, and not stable.
#2 Lighting
Lighting is very important when taking a picture. If it's too dark, you won't be able to see the subject. If its too bright, then it will look too overwhelming. There are different types of lighting in photography such as: Sufficient, Insufficient, lit from above, lit from below, and lit from the side. If the photo is too dark, it may look too scary. If the photos light, it makes you feel at ease, and more calmer. But it really depends on what you want the viewer to think about the picture. Like if the picture was meant to be dark and scary, or if the picture was meant to be very bright.
#3Proximity
Proximity in photography is how far, or how close you want the picture to be shown as. Like the distance in the picture. The distance in the picture could be: far from the subject, medium-long, medium (face and torso), a close up, and an extreme close up.
