Studio scene comparison (RAW)

In order to achieve as near to a level playing field for comparison as possible, we also shot our studio scene in RAW mode with each camera and converted it using Adobe Camera RAW (in this case ACR 5.6). Because Adobe Camera RAW applies different levels of sharpening to different cameras (this confirmed) we 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.

Nikon D3S vs. Nikon D300S

Nikon D3S
Nikon D300S
4.1MB JPEG (4256 x 2832)
4.6MB (4288 X 2448)

The results from both of these cameras are again, virtually indistinguishable from one another. It seems (unsurprisingly) that in favorable conditions, at base ISO, the full-frame sensor of the D3S offers no tangible advantages in image quality over the smaller, equal resolution sensor of the D300S. Both cameras, however, are capable of better image quality in raw mode, but again, this is entirely to be expected.
