: At its simplest, an image is a 2D array where each pixel has a specific location and an intensity value representing brightness.
The transition from raw data to a finished photograph involves a rigorous multi-step workflow. Imaging Data and Space Photography
: High-quality archival data includes rich metadata such as precise timestamps, exposure duration, spatial scale, and the target's latitude/longitude. How Raw Data Becomes Photography : At its simplest, an image is a
: To ensure accuracy, technicians take additional frames like Dark Frames (to reduce thermal noise) and Flat Frames (to remove dust spots and gradients). : At its simplest
: Non-optical telescopes detect radiation invisible to the human eye, including radio waves , infrared , X-rays , and gamma rays .
