1. %keyword%: What Are They?
1.1. Definition of a Camera
A camera, in its simplest form, is a device that captures images by recording light. It consists of a lens, which focuses light onto a sensor or film, and a shutter, which controls the duration of exposure.
1.2. Types of Cameras
Cameras come in various types, each optimized for specific purposes:
- Digital Single-Lens Reflex (DSLR): High-quality cameras with interchangeable lenses, providing flexibility for professional photographers.
- Mirrorless Interchangeable-Lens Camera (MILC): Compact cameras with similar capabilities to DSLRs, but without a mirror mechanism.
- Compact Digital Camera (Point-and-Shoot): User-friendly cameras designed for everyday use, with fixed lenses and simplified controls.
- Action Camera: Durable cameras designed for capturing extreme sports and outdoor activities.
- Smartphone Camera: Integrated cameras in smartphones, offering convenience and portability.
