K10D 的JPG dynamic range(DR)窄的说法,源自dpreview的test report.
见[1] http://www.dpreview.com/reviews/pentaxk10d/page15.asp
但同页的另一张图,指出K10D Raw的DR:"The best we could achieve (with some pretty
extreme ACR settings) was just over 10 stops total dynamic range"
另一个更细致的测试见:

[2]和[1]测试方法不同点在于:[2]比较各款DSLR在不同noise thresholds下最低ISO的动态范围.结论是在high image quality下,
