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. 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.

Pentax K20D vs. Pentax K10D

Pentax K20D
Pentax K10D
4.0 MB (4672 x 3104)
3.0 MB (3872 x 2592)

Applying the same processing to the raw files of both the K10D and K20D is pretty revealing. It shows both how much detail the K10D was capable of producing, once liberated from the confines of its JPEG engine and how much of an improvement Pentax has made on that front with the K20D. Without the relatively high level of sharpening the K20D's JPEGs have as default, its output is much less striking but probably more balanced overall. Camera Raw seems to have lowered the K20D image's contrast a little, though.
