The DP71 was launched in 2006.
Image noise is reduced by the CCD cooling mechanism. The DP17 can vividly capture weak fluorescent light and produce high-resolution fluorescent images. The CCD includes 1.41 effective megapixels but is capable of resolution equivalent to 12.5 megapixels with piezo shift technology. A spot measuring method is used for light measuring, with the camera capable of switching between 30%, 1%, and 0.1% average fixed spots.
Microphotography that had proved difficult with 35mm film cameras has become much easier with digital camera technology. Microphotography has now switched from silver halide to digital media. We have been through a generational shift in terms of both picture quality and ease of use.
