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 5.4 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. i

When we applied the workflow that is detailed above to the Ricoh S10 24-70 mm's DNG files we found, just like on the A12 module, 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). We've tried a range of RAW converters with the S10 files (see also the RAW page of this review) and found that Graphic Converter 6.7 (DCRaw) got us the most detailed results. This page shows the Graphic Converter output compared to Adobe Camera RAW. For consistency we have stuck with the ACR version for the comparisons on the following pages.

Adobe ACR 5.6 vs Graphic Converter 6.7 (DCRaw)

Ricoh GXR/S10 24-72mm (ACR)
Ricoh GXR/S10 24-72mm (GC)
3.6 MB JPEG (3648 x 2736)
3.5 MB JPEG (3648 x 2736)

The Graphic Converter (DCRaw) image is visibly sharper with more detail (see the coin in the first crop) but on the downside shows more noise in shadow areas of the image. We've seen in the RAW noise section of this review that in ACR (and by the looks of it most other RAW converters) noise redcution is applied to the GXR RAW files. The samples above suggest that in DCRaw that's not the case.
