FrozenInTime Posted January 21, 2017 Share #21 Posted January 21, 2017 Advertisement (gone after registration) what would a ND do differently than a proper exposure compensation or exposure setting? If the subject dynamic range is beyond that of the sensor, e.g. subject indoors at a window with a sunlit exterior, there is no single correct exposure that captures all the detail in the scene. Extending the sensor design to improve dynamic range would help in this situation. However with an increased dynamic range sensor, it is also important that the output bit depth of the analog to digital and de-mosaicing conversion is increased to maintain separation of details in low contrast scenes.

esquire53 Posted January 21, 2017 Author Share #22 Posted January 21, 2017 I think the dynamic range refers to the ISO range, not the A/D resolution Link to post Share on other sites More sharing options...

The effect would be to broaden the exposure range of the sensor as a whole, at the expense of resolution and ceiling ISO. At the end of the day, though, one would still need to ensure that the final, interpolated, full exposure-range image did not itself have blown-out highlights.

Joshua Lowe Posted January 22, 2017 Share #25 Posted January 22, 2017 How would that work? Conceptually, I've considered a few possibilities. Something akin to bracketing, but designed specifically with highlight preservation in mind. Or visual indicators like zebra striping when using EVF/LV. Bringing back the RAW histogram and zone indications from the original Monochrom would certainly be a step in the right direction, particularly if they were live.

muri Posted January 22, 2017 Share #26 Posted January 22, 2017 The next Monochrom needs highlight protection. The fragility of highlights was by far the biggest drawback for me. Shooting in bright daylight or high contrast environments was like trying to delicately cook an egg on a 2000 degree surface. If you change the light meeting from classic to advanced, it doesn't overexpose. But it is slower... Link to post Share on other sites More sharing options...
