Comparison of image detail and sharpness with EOS-1Ds, EOS-1D Mark II, 20D, D60 and EOS-1V with Astia 100F film.. All images were produced at ISO 100 with EF 28-70mm f/2.8 L lens at f/8, aperture priority, evaluative metering, automatic white balance on the same late afternoon. Partly cloudy conditions resulted in slight lighting variation (e.g., lighting was brightest during the EOS-1Ds exposures). Cameras were in sRGB color space with standard factory parameter settings. Three exposures were taken, and the sharpest image was selected to minimize effects of autofocus variation. All digital images shot in RAW and converted to 300 dpi tif with C1 Pro v. 3.5 with exception of the 20D images which were converted with Canon DPP v1.1. Cropped section converted to 72 dpi pixel image in Photoshop 7. Astia 100F Negatives were scanned with Nikon Super Coolscan 4000 ED scanner with autoexposure function with post-scanning adjustment of contrast and brightness. All images subjected to slight unsharp mask. Note: The lower shadow detail in the 20D images is most likely accounted for by differences in RAW processing software (C1 Pro vs. DPP) rather than camera differences. RAW 20D images will be reprocessed and posted here once Phase One updates C1 Pro for the 20D.
