Yet another good photo/camera related article on noise (titled "Noise, Dynamic Range and Bit Depth in Digital SLRs" and referenced in Luminous Landscapes's "What's New" web page) is now available. According to LL the article : [QUOTE] . . . appeared online this week. It's quite academic and will take time to digest, but for those that care about this topic beyond the practical level, highly recommended.[/QUOTE] The multi-page article includes data from, and credit is given within to rpd/rpdss regulars Roger (N.) Clark and John Sheehy and others. [URL]http://theory.uchicago.edu/~ejm/pix/20d/tests/noise/index.html[/URL]
