BMP vs DNG
Ein detaillierter Vergleich von BMP Image und Digital Negative (RAW) — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
BMP Image
Raster & Vector ImagesBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
Über BMP-DateienDigital Negative (RAW)
Raster & Vector ImagesDNG is Adobe's open RAW image format designed as a universal standard for camera raw data. It preserves full sensor data and extensive metadata, making it ideal for non-destructive photo editing.
Über DNG-DateienVorteilsvergleich
BMP Vorteile
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
DNG Vorteile
- Open, documented standard (ISO 12234-2) — future-proof for archival.
- Based on TIFF — broad tool support beyond Adobe.
- Can embed the original proprietary raw as a safety copy.
- Smaller than most proprietary raws thanks to lossless compression.
- Stores every Adobe Camera Raw adjustment inline, so edits travel with the file.
Einschränkungen
BMP Einschränkungen
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
- Multiple header versions mean "a BMP" is ambiguous — parsers must handle several variants.
DNG Einschränkungen
- Canon, Nikon, Sony, Fuji still refuse to adopt it.
- Some manufacturer-specific features (Fuji film simulations, Nikon Picture Control) are lost in conversion.
- Slower workflow — RAW from camera must go through DNG Converter first.
- Mobile ProRAW files are heavy (25-75 MB per shot on iPhone).

PNG is better than BMP in almost every scenario since it provides lossless compression (smaller files), transparency support, and wider cross-platform use. BMP is mainly relevant for legacy Windows applications.
