Studio scene comparison (RAW)

For a (more) level playing field for comparison we also shot our studio scene in RAW mode with each camera and converted it using Adobe Camera RAW. Because Adobe Camera RAW applies different levels of sharpening to different cameras (this confirmed) we had to use the following workflow for these conversions:

  • Load RAW file into Adobe Camera RAW (Auto mode disabled)
  • Set Sharpness to 0 (all other settings default)
  • Open file to Photoshop
  • Apply a Unsharp mask: 80%, Radius 1.0, Threshold 0
  • Save as a TIFF (for cropping) and as a JPEG quality 11 for download

This is our standard studio scene comparison shot taken from exactly the same tripod position. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F). Camera settings as per previous pages (24-70mm f2.8 L lens)

Canon EOS-1DS Mark III (RAW) vs.
Canon EOS-1DS Mark II (RAW)

Canon EOS-1Ds Mark III (RAW)
Canon EOS-1DS Mark II (RAW)
5.5 MB JPEG (5616 x 3744)
4.5 MB JPEG (4256 x 2382)

Interestingly switching to raw and using the same processing (and crucially the same sharpening) shows that the resolution gap between the Mark III and the Mark II is minimal, and (aside from differences in depth of field) the output from the new camera is pretty similar, just bigger (you're getting maybe 10% more resolution in each direction).
