Photography is the art and science of capturing light to create images, built on a foundation of technical principles and creative vision. At its core, photography requires understanding the exposure triangle (aperture, shutter speed, ISO), mastering composition techniques, and controlling how light interacts with your camera's sensor. Unlike painting or drawing where you create from nothing, photography involves making critical decisions about what to include, exclude, and emphasize within a fraction of a second—meaning technical proficiency must become second nature to free your creative mind. The key insight: your camera captures what the sensor sees, not what your eye perceives; learning to "see" like your camera, especially through the histogram, transforms snapshots into intentional photographs.
