ND Adjustment

I read the Abel Cine post describing the ND Adjustment feature that was unlocked within the firmware update 1.10.
"ND Adjustment – They have also enabled a slight color adjustment for the different ND filters. By adjusting these values, you can compensate for any color shift introduced by the ND filters."

This seems ridiculous as the F3 has plenty of color adjustment. I asked Joseph Schimizzi at Cine Gear yesterday he said the USA Sony people don't even have an updated manual for the new firmware release. Joe is looking into this for me and I will see him again later today.

I believe it adjusts/creases the amount of gain/ISO. The setting can dial up from Zero the 999. My gear is out right now so can anyone confirm the increase and how much the maximum 999 adjusts in stops?
 
Joe Schimizzi said he still didn't get the an answer to the ND feature but thought it was once called a Master Gain on older cameras.
 
Is it possible they added color adjustment to the ND so one can go form indoor lighting to outdoor and with a simple click of the ND wheel one can adjust both ND & Color balance. While the F3 is not a run and gun camera I can see where this convenience might come in handy in some unique shooting situations.
 
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.

I think I get it

I often think the ND wheel works too heavy. ND 1 being almost like a 2 1/2 or 3 stop difference. Sometimes all you want is a stop or so. That being said, now, instead of having to pull out an N3 filter for those small adjustments, you can adjust the value of the ND filter.

Does this make sense to anyone else?
 
Yes, it does make sense. I have the same issue and want to know exactly what 1/8 and 1/64 equate to in filter terms--ND6? ND9? Would be good to be able to control that. I believe we need an engineer to pipe in here!
 
That's why I picked up Schneider ND.3 (1.5 stops) and ND.6 (2.5 stops) to have more variation of the ND filters (since Sony only includes 2 ND filters instead of three.) The abrupt ND changes work but are a bit harsh for exact control.
 
You guys are mixing things up.The decimal point is very important. ND .3 = one stop, ND .6 = two stops ND .9 = three stops. ND2( no decimal point) = cuts the light in half, One stop. ND8 ( no decimal point) cuts the light by 1/8 or three stops ND64( no decimal point) cuts the light by 1/64 or 6 stops.
 
The question is, can we change them to Nd.3 and ND.6 equivalent with the 1.1 firmware update? And what would that be? Only has whole numbers. Will play around with it next week and try to figure it out. Thanks everybody.
