I've got a waveform vectorscope I'll see what effect it has. Is their any particular tests someone wants done?

Interesting, on the scopes it appeared to be adjusting the color slightly as well. I'll test this again to see, whatever it did was very slight.

Re: New ND-adjustment feature?
 
OK I have preformed a very unscientific experiment with the ND Adjustment feature using my Panasonic BT-LH1760p monitor using the waveform and vector scope. I pointed the camera at a white box and covered a portion to darken the area just behind the number counter in hopes it would aid in reading it from the still pictures I took. I started with setting a stop that put the waveform right at the 50% mark and I never changed the aperture during this test , I then dialed up the counter of the Clear ND to 333, it moved the waveform exposure to 60%, I then dialed the Clear ND to 666 and it move the waveform exposure to 70%, then I dialed the Clear ND counter to 999 and it move the waveform exposure to near 80%. At each point I took a picture of the waveform monitor and vector scope and from what I see the ND Adjustment feature only adds gain and doesn't change any color.
