Sobre os arquivos NEFComparativo de vantagens
GIF Vantagens
- Universal animation support — every browser, every chat app, every social network.
- Transparent backgrounds for compositing against any page color.
- Lossless for its limited palette — pixel-perfect at 256 colors.
- Self-contained: no codec, no browser plugin, no third-party player needed.
NEF Vantagens
- Deep metadata — Active D-Lighting, Picture Control, lens profile all preserved.
- Backward-compatible since 1999.
- Supported by every major raw processor (Lightroom, Capture One, DxO, Darktable).
- Embedded full-size JPEG preview.
- Lossless or moderately compressed variants available.
Limitações
GIF Limitações
- Limited to 256 colors per frame — looks posterized on photographs.
- Dithering for color-rich images makes files huge (often 10× an MP4 equivalent).
- No audio track.
- Transparency is 1-bit (on/off) — no smooth alpha blending.
- Poor compression compared to modern formats (WebP, MP4, AVIF).
NEF Limitações
- Proprietary — no official spec.
- Some Nikon makernote features don't round-trip through third-party tools.
- File sizes are large (20-60 MB typical).
- The 2005 encryption episode damaged trust in the format.
