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 (version 5.6 in this case). 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.

When we applied the workflow that is detailed above to the Ricoh A12 50mm's DNG files we found that the results are softer and less detailed than the camera's out-of-camera JPEGs. It appears ACR's RAW conversion routines for the GXR's DNG files are not fully optimized (yet). This can be easily fixed by simply applying more sharpening during RAW conversion. The image on the left is the result of our usual workflow. Additional sharpening was applied to the image on the right in ACR (Amount 88, Radius 0.5, Detail 49, Masking 8). Although the image on the right is over-sharpened it does show that there's a lot more in thefile than the default output might suggest. For consistency we have stuck with the left version for the comparisons on the following pages.
