1. Re: Using a calibration target with a waveform monitor to get the right contrast?

You are doing it kind of wrong.
What you should use that Black /Grey White TOOL for is to set an exposure at the camera. (NOT in Post Production..but it does have an application in post)
If your Camera has the Zebras set at 95-100% White...you would point camera at the "TOOL" and adjust exposure so that the zeras display on the white section. You can not do anything about the black. (It will fall into place from the exposure on the white)
Now the above assumes that as a photographer...you actuall want the white level to photograph as white for the particular shot that you are taking.
Exposure is all about tones. Black to white thru grey tone actually. (Forget about color)
Hope this helps but I am happy to expand if you wish.

JSS1138 Nov 29, 2010 8:45 PM (in response to shooternz)You can not do anything about the black.
You can adjust the pedestal in a lot of cameras. This may help bring the black down into black if it isn't already.

Dave Dugdale Nov 29, 2010 8:49 PM (in response to JSS1138)@Jim I have a Canon T2i, I have read the manual a couple of time but I not sure I saw a pedestal adjustment. I will keep looking, thanks for your help.

shooternz Nov 29, 2010 9:28 PM (in response to JSS1138)I cant recall a Ped in any Digital Camera I have used but possibly hidden away in a menu somewhere.
I used to have a tweaker for this purpose in the old studio cameras much to the chagrin of the Tech Dir.s of the time.
The way I obtain Black in a scene is by lighting up the mids and high lights in the scene and exposing accordingly.
I also use negative fill.
I usually leave some detail in Black so I can move it in post.

Dave Dugdale Nov 30, 2010 7:44 AM (in response to shooternz)@shooternz what is negative fill?

shooternz Nov 30, 2010 11:26 AM (in response to Dave Dugdale)Negative fill can be a black board or cutter placed in a position to prevent any bounce or fill light coming from a direction that you want to control.
eg you have a key light on the right hand side and there is ambient or bounce light coming in from the left that you dont want. A "black" will cut this off the subject.
Its the opposite to fill light from a white surface or reflector.

My lowly Panny DVC80 has it. (It is a menu setting, one of the Scene File adjustable options.) I can't believe your HVX doesn't.

shooternz Nov 30, 2010 7:30 PM (in response to JSS1138)I will take a look at the DVX and the HVX.
I dont go into the menu much. I got a AC that knows the gear far better than I ever would.
I checked and yep... I got Master Ped in the DVX and the HVX cams. menus.
Now ...where did I put that darn "tweaker"?
