Originally posted by Derwin Purely in terms of maximising data-rate and minimising compression artefacts, and lets also set aside for the moment any considerations regarding the creative or technical limitations this may put on your available options in post, is there any advantage to be had in shooting direct to a tweaked-to-taste B&W picture style in-camera?
Only if you're delivering B&W product - you can't put the colour back in.
De-saturate by all means, but B&W means B&W, not simply colour reduced.
On the CoDec, pricture styles, and the like,... This afternoon I hooked up my K-01 to my Canopus ADVC100 via the camera's analog and sent the firewire connection in to Adobe OnLocation to display the waveform and histogram monitors,.. And had another camera recording the screen.
With the K-01 looking outside, I went through the Natural and Muted picture styles, and adjusted the Contrast and High/Low Key adjust to see what really happens.
Contrast up stretches white and black away from each other, down compresses them towards each other.
High/Low Key adjust works more like a screens Brightness control, more then like a TV camera's Gamma Knee - which is what I thought it did before.
So, by setting the exposure (ISO/Iris/Speed) to gain correct exposure overall, reducing Contrast lifted the blacks and lowered the whites, and then lowering the High/Low Key allowed me to reduce the over exposure of the sky while maintaining the overall correct exposure of the garden.
I have yet to check the vision the K-01 recorded at the time in Edius to compare the waveforms, but it's my opinion that reduced Contrast is better at preserving more information within the range of the standard video signal before compression.
High/Low Key biases the available space within the signal to have either more space for the highlights, or more for the Lows, at which point it becomes more a matter of how bright or dark your scene is - shooting outdoors in daytime, lower the High/Low Key, shooting in a dark room or at night, raise the High/Low Key to get more information in the dark areas of the frame.
I'll post the video of what I was recording to my Vimeo once I put a decent narration over it..... maybe with someone elses voice.
