Studio scene comparison (JPEG)

This is our standard studio scene comparison shot framed to match (as closely as possible) vertical framing. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F).

Sigma DP1 vs. Nikon D60 (downscaled image)

Camera settings:

  • Sigma DP1: Aperture Priority, ISO 100, JPEG Large/Fine, Manual WB
    Default Parameters, Self-Timer

  • Nikon D60: Nikkor 50 mm F1.8 lens, Aperture Priority, ISO 100
    JPEG Large/Fine, Manual WB, Default Parameters, Self-Timer

For the purpose of this comparison we have downscaled the Nikon D60's images to match the size of the DP1's output. The images were resampled using the Bicubic Sharper option in Adobe Photoshop CS3.

At an identical viewing size the DP1 is still slightly ahead in terms of per pixel detail (check the tree on the Baileys bottle) but after reducing the D60 image the difference is not as obvious any more. The Foveon sensor can clearly capture a remarkable amount of detail but the Nikon's Bayer sensor makes (at least partially) up for it by recording a much larger image.
