Nikon has announced two new versions of its D1 professional-quality single-lens reflex (SLR) digital camera, both with new ICC-compatible internal colour spaces.


The high-resolution D1X uses a new CCD to capture 5.32m pixels, output as a 3,008x1,960 pixel 16.88MB image file.


The original D1s 2.7mp CCD produced very clean, low-noise images and Nikon claims to have further improved noise reduction, so the D1X images should be suitable for full-page A4 or larger reproduction at magazine screen rulings.


The D1H uses the original 2.7mp CCD, but has been modified for very fast shooting of up to five frames per second for news and sports use the large buffer memory can store up to 40 consecutive shots and a sensitivity range of 200-1,600 ISO. This is the fastest digital SLR to date. The D1X operates at 3fps for nine shots and has a sensitivity range of 125-800 ISO.


Both cameras include two built-in colour modes: the sRGB colour space optimised for web/monitor and the Adobe RGB 1998 space for pre-press. The latter should fit straight into Photoshops standard colour management workflow. Both can output 8- or 16-bit pixel depths in a choice of RGB TIFF, YCbCr TIFF, RGB JPEG or Raw modes.
