Most Gaussian Splatting projects see diminishing returns above 30MP.

RAW Format Importance

RAW capture is essential for quality Gaussian Splatting work. RAW files contain complete sensor data without compression. This extra information helps reconstruction algorithms create cleaner point clouds. All recommended cameras except the Canon EOS R100 support RAW capture. The difference between RAW and JPEG becomes apparent in challenging lighting conditions. When scanning interiors with mixed lighting, RAW files recover detail in shadows and highlights that JPEG loses permanently.

Lens Selection

Wide-angle lenses between 16mm and 35mm work best for most Gaussian Splatting scenarios. Prime lenses typically offer better sharpness than zooms. A 24mm prime lens provides excellent coverage for interior scanning. APS-C cameras need wider focal lengths to achieve equivalent fields of view. The Sony 20mm f/1.8 G lens pairs beautifully with the a6400 for interior work. Full-frame shooters should consider 28mm or 35mm primes for balanced coverage.

High ISO Performance for Interior Scanning

Interior Gaussian Splatting often requires high ISO settings. Full-frame sensors excel here with cleaner results at ISO 1600-6400. The Sony a7 III maintains usable images even at ISO 6400. APS-C cameras typically show more noise above ISO 1600. When scanning dimly lit spaces, full-frame cameras provide cleaner files for reconstruction. This advantage alone justifies the extra cost for interior scanning applications.

Budget Considerations

Gaussian Splatting cameras range from under $600 to over $3000. The Canon EOS R100 provides an entry point under $600 for learning basics. The Sony a6400 around $1500 offers excellent value for serious work. Full-frame options like the Sony a7 III near $2000 deliver professional results.
