The only thing I am still confused about.
 
ALRIGHT!

For the last time... High Knee vs. Low Knee... Which more closley approximates the natural highlight curve of film? Does high refer to the high point on the chart, and thus, a more sharp cutoff, or does Low refer to the amount of detail in highlights? I have gotten conflicting reports.

GAH!

LOW knee is what you want. This can sometimes give a bit of a milky look if you are in shadow but it does emulate film better. High knee will cause highlights to blow out to pure white.

To get the most detail and range out of an XL2 you can set the knee to low and the black to stretch. There is no other 1/3" SD CCD camera that can get that much detail and information out of the image.

Thanks Ash.

Love all your presets and such. Good to have an expert around.
I don't like the look of stretched blacks, looks quite video-e. Ugh

Stretching the blacks though will preserve detail during acquistion so that you have something to post process with. That's the whole concept in a nutshell. You can't work with what you don't have. Another good example is that you can't recover blown out highlights so definitely lower the knee so that the curve does a more gradual roll-off in response to brighter areas.
