Studio scene (Adobe Camera 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:

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.

In both cases we used our standard workflow (sharpening turned off in the raw converter and applied at an equal level in Photoshop before saving as JPEG):

  • Load RAW file into Adobe Camera RAW
  • Set Sharpness to zero (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

In this instance, because it more accurately matched the JPEG's brightness levels, we have processed both Canons using the 'Camera Standard' profile in ACR that attempts to match the manufacturer's rendering of colors.

Compared to... Canon PowerShot G10

Canon PowerShot G11
Canon PowerShot G10
ISO 80, 1/60 sec, F4
ISO 80, 1/60 sec, F4
3.5 MB JPEG (3648 x 2736)
5.6 MB JPEG (4416 x 3312)

If anything, the G10's advantage over its sibling is increased by processing the RAW files. In particular, the combination of the G10's sensor and Adobe Camera Raw's processing excels at the patterned detail in the third and forth crop. What is noticeable, however, is that ACR does not attempt to match the rather high sharpening that the Canons' JPEG engines produce.
