Raw format refers to a type of digital file that captures unprocessed data directly from a camera's sensor. Unlike standard image formats like JPEG or PNG, which compress and alter the image, raw files retain all the original information, allowing for greater flexibility in editing. This is particularly useful for photographers who want to make significant adjustments to exposure, color, and detail without losing quality. Raw format files are typically larger than compressed formats due to their unaltered nature. They require specific software, such as Adobe Lightroom or Photoshop, to open and edit. Because of their high fidelity, raw files are favored by professionals who need the best possible image quality for printing or large displays.
