When do you white balance and what is your FS700 white balance workflow and why?

There is a tutorial that covers color grading at Free Final Cut Pro X Grading Tutorials (http://www.colorgradingcentral.com/final-cut-pro-x-color-grading-table-of-contents)

In the early part it talks about the order of operation, or workflow.

There are quite a few things to consider, such as exposure and "Look Building" before one even gets to the workflow of contrast and color balancing.

The tutorial uses FCPX so while your application may be different the sequence should be the same.

Can't speak to the camera question.

Now that was a very good resource!
