Studio scene comparison

This is our standard studio scene comparison shot taken from exactly the same tripod position within minutes of each other. Lighting: 2 x 800W studio lights with dichroic daylight filters bounced off a white ceiling reflector. Crops magnified 200%. Ambient temperature was approximately 21°C (~70°F).

Kodak DCS Pro SLR/c (ISO 160) vs. Canon EOS-1Ds (ISO 160)

As you can see the EOS-1Ds proves to be almost a stop more sensitive than the Pro SLR/c, you can see a comparison with 'best settings' (EOS-1Ds at ISO 100) below. A parameter set with a sharpening setting of +2 was used on the EOS-1Ds to compensate for that camera's very low default sharpening (even with this setting sharpening is not as visibly strong as the SLR/c).

Camera settings:

  • Kodak DCS Pro SLR/c: Canon EF 50 mm F1.4, Aperture Priority,
    ISO 160, JPEG Large/Fine, Manual WB, Mirror Lock-up self-timer
  • Canon EOS-1Ds: Canon EF 50 mm F1.4, Aperture Priority,

There's little doubt that the SLR/c's additional 2.5 million pixels are resolving more details in some parts of the image, however it's also noticeable that some of this additional resolution is being destroyed by Kodak's heavy handed noise reduction algorithm. This is perhaps most noticeable in the crop of the Bailey's label where the tree detail is rendered far better on the EOS-1Ds. The EOS-1Ds here appears noisier than the SLR/c, it doesn't have any built-in noise reduction (other than for night exposures) and we have increased its sharpening level which will enhance the visibility of noise (on the next page you will find a strictly 'fairer' comparison with the EOS-1Ds at ISO 100). Other differences are the SLR/c's moiré which can be seen in various places around the image, the EOS-1Ds image has almost none.

Color wise I prefer the more vibrant appearance of the SLR/c image although it does have an overall slight green color cast probably introduced by Kodak's Lens Optimization (which was set to Auto), if you look at the third page of this comparison section you'll note that the converted RAW file doesn't suffer from this green cast.
