Ki Pro Mini and picture profiles/cinegammas

I have decided to use the Ki Pro Mini as my external recorder for the F3 but I am still confused as to how I am supposed to expose when recording 10-bit 4:2:2 without S-Log (unfortunately S-Log will not be an option for me).

I know that when using S-Log that the picture profiles are disabled so that grading can be done in post. If I am only recording 4:2:2 to the Ki Pro Mini are the picture profiles still going to be enabled? If so, what should I set the profiles to so that they will have the most flexibility in post?

Finally, do I need to make any compensation when shooting 4:2:2 without S-Log? I have heard that when shooting with S-Log that you are supposed to shoot middle grey at a lower exposure.

Thanks.
 
Where you expose your "grey" and which cinegamma you use will depend largely on what else is going on on the scene. ie. when would you need more range in the low-end verus the high-end? Or when might you want even amounts of range above and below your mid point? These are the questions you need to answer when shooting with SLOG, or without SLOG and cinegammas. Whether you shoot 420, 422 or 444 really doesn't impact how you chose your exposure in my opinion.

I use a lightmeter to set my grey point and get consistent light exposure on my skin from scene to scene, location to location, light source to light source. If you don't have one or don't want to fiddle with one, then use the marker function on the F3, or better yet use a waveform monitor on an ext. LCD to see your levels and get an idea of what's going on in your scene.

Use this handy guide I put together to illustrate the different gamma curves and where middle grey is found: http://www.starcentral.ca/Sony PMW.pdf
 
Below was a really good thread with some opinions/debate on how to set exposure on the F3. ie. using a meter, zebras, exposing for highlights, etc..

DVX thread.

Also found on page 2 of that thread is some information I subsequently posted on my blog with sample frames I shot and the technique/settings I used to expose various images.
