Highlight range in raw will normally match that in JPEG quite closely. In
addition, there'll be about a stop more recoverable in the highlights, but
with no guarantee of colour accuracy (due to successive clipping of the
colour channels).
For the shadows, see our fairly-standard 3 stop push test, and the gradation
demonstration, here: http://www.dpreview.com/reviews/olympusem5/15
In practical photographic terms, this should cover what you most need to
know."
"3 stop push test"测试的结论是"Trying to push-process our dynamic range test
shot shows the E-M5 is able to capture a similar range of tones in the
shadows as the NEX-5N, suggesting it's not simply giving cleaner shadows by
clipping to black sooner than the Sony."
也就是说通过用raw做的3 stop push test测试, EM5和NEX-5N的宽容度基本一样. |
