Sigma DP1 Review
Studio scene comparison (RAW)
For a (more) level playing field for comparison we also shot our studio scene in RAW mode with each camera. Usually we convert the images using Adobe Camera RAW but unfortunately ACR cannot read the DP1's RAW files. Therefore we have used Sigma's Photo Pro 2.5, which is currently the only available RAW converter for the DP1, to convert the DP1 images.
Sigma DP1 (RAW) vs. Nikon D60 (RAW)
- 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
- Sigma Photo Pro 2.5, default settings.
1,442 KB JPEG (2640 x 1760)
2,706 KB JPEG (3872 x 2592)
As you can see both cameras' RAW images look crisper and exhibit better detail than their JPEG counterparts but in relative terms the picture has not changed. The DP1's Foveon sensor is capable of capturing amazing pixel detail but the Nikon D60 makes up for that by simply capturing a significantly larger number of pixels.
