What is TGA?

Truevision TGA/Targa is a raster graphics format widely used in video editing, 3D modeling, and legacy computer graphics.

What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

When Should You Use TGA vs ORF?

Use TGA When...

Reach for TGA when your priority is video editing, 3d textures, legacy graphics — its uncompromising quality ensures every detail is preserved.

Use ORF When...

Reach for ORF when your priority is olympus camera raw processing — its uncompromising quality ensures every detail is preserved.

TGA vs ORF: Key Differences

  • •TGA and ORF diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: N/A
  • •Storage footprint: Larger than BMP, smaller than an uncompressed TIFF for TGA vs 15-40MB per photo for ORF.
  • •Use case fit: TGA targets video editing, 3d textures, legacy graphics and ORF targets olympus camera raw processing — your choice depends on which workflow stage you are serving.

Advantages of TGA

  • ✓The lossless nature of TGA means file sizes stay reasonable while handling Video editing, 3D textures, legacy graphics efficiently.
  • ✓From mobile devices to enterprise servers, TGA is recognized and supported everywhere.
  • ✓The trade-off for TGA's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓TGA is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Best Practices for TGA to ORF Conversion

  • →Before converting TGA to ORF, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to ORF — you cannot recover detail lost during lossy compression
  • →Check the color profile: TGA images may use a wider gamut than ORF supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting TGA to ORF Conversion

  • !Converting TGA to ORF gives blurry output → increase the quality setting before conversion
  • !Colors look different in ORF than TGA → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → ORF uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in TGA turned white in ORF → ORF may not support transparency
