Studio scene comparison (RAW)

For a (more) level playing field for comparison we usually 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 has beem 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

However, because Adobe Camera RAW doesn't appear to be capable of rendering the levels of detail we'd expect, we're testing it against the output from Phase One's Capture One Pro. In this instance we've matched the exposure back to the brightness of the JPEG and ACR output, then disabled all sharpening, before subjecting the resultant TIFF to our standard sharpening routine (described above).

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.

E-620 (RAW) Adobe Camera Raw vs. E-620 (RAW) Capture One

E-620 (RAW) Adobe Camera Raw
E-620 (RAW) Capture One
3.3 MB JPEG (4032 x 3024)
4.8 MB JPEG (4032 x 3024)

We have been given reason to believe Adobe Camera Raw's handling of files from the latest generation of Olympus DSLRs was not fully optimized, not least because it doesn't seem capable of rendering as much fine detail as the camera's JPEG engine. Looking really closely Capture One appears, in this instance, to be doing a slightly better job of representing the very finest detail from the E-620, so, to ensure we are not showing the Olympus in an unfair light, we will use the Capture One crops on this occasion but, as you can see, the results would be very similar even if we'd used ACR.
