RAW is not one format — it’s a category. The term dates back to the Kodak DCS 100 (1991), the first commercial digital SLR, which stored unprocessed sensor data in a vendor-specific container. Every subsequent digital camera added its own raw format (Canon CR2/CR3, Nikon NEF/NRW, Sony ARW, Fuji RAF, Olympus ORF, Panasonic RW2, Leica DNG, Pentax PEF, Sigma X3F…) — over 40 distinct raw dialects exist in 2026.

The generic .raw extension, when encountered, almost always comes from a very old camera (Panasonic pre-2008, Kodak/Leica legacy, Fuji pre-2003) or a scientific/industrial imaging tool. Modern cameras use their own branded extension. Practitioners and raw processors use "raw" as shorthand for the entire family.

MERAK EDİLENLER VE
İLGİNÇ BİLGİLER.

Over 40 distinct raw camera formats exist in 2026 — each manufacturer fiercely protects its own dialect.

The first commercial digital SLR, the Kodak DCS 100 (1991), already stored raw sensor data — the concept is as old as digital photography.

Raw files are often called "digital negatives" because they contain unprocessed sensor data, like a film negative before development.

Converting raw files to DNG is the most common way to consolidate a library that spans multiple camera brands.

Raw files weigh 2-6× more than equivalent JPEGs because they store one value per sensor pixel at full bit depth, without demosaicing.

GÜÇLÜ YÖNLER VE
SINIRLAMALAR.

Güçlü Yönler

Every bit of sensor data preserved for post-processing latitude.
Higher bit depth (12-16 bits) than JPEG (8-bit) — smoother gradients.
Non-destructive editing in raw processors.
Rich metadata (EXIF, makernotes, camera settings).

Sınırlamalar

Proprietary per brand — Canon CR2 will not open in a pure-Canon-free processor.
Huge files compared to JPEG.
Requires dedicated software (Lightroom, Capture One, Darktable, etc.).
No universal standard — DNG aims to solve this but adoption is partial.
