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 (in this case a Beta version of ACR 5.6 - the only version available that supports the EOS 7D). 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.
Nikon D300S vs. Canon EOS 7D
Canon EOS 7D
4.6MB JPEG (4672 x 3104)
6.1MB JPEG (5184 x 3456)
As we have become accustomed to seeing, the Nikon produces a much more comparable image when processed from RAW. The higher pixel count of the 7D gives it a slight edge at capturing the finest detail but there's really very little to call between the two - it's hard to think of a situation in which either of these cameras could be claimed to be better than the other, in image quality terms.
