Similar to humans, cancer is the leading cause of death among older cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any parts of the body.
Adaptive headlights make driving at night or under low-light conditions safer, by adjusting the car's headlights to curves in the road. Rather than pointing directly at the space in front of the vehicle, they adjust to illuminate the area that the car will occupy next.
Back lighting is when the light source comes from behind the subject. This gives a new dimension within the background and has the ability to create silhouettes. For example, within the 'Se7en' trailer, the use of back lighting is used to create a shadow. This is effective as it creates mystery around who the figure is, emphasising the mystery/thriller genre of the film. Low Key Lighting is created by using the key and back lights. Used together, they produce a sharp contrast between light and dark areas on screen.
