Re: black/white look
Joerg,
I think the best technique is to shoot in color and desaturate in postproduction. By selectively combining the red, green and blue channels--you can simulate the use of any common b&w filter (red, orange, yellow, green). For instance, if you want white clouds against dark dramatic skies--choose only the red channel and it will look like you shot b&w film with a red filter.

Re: black/white look
This question of how best to shoot b&w with miniDV came up on another forum a while back. The definitive answer was that it made no difference if you shoot in color and convert to b&w in post. Additionally, you have a color original for use later or as sellable stock footage. I don't have the original post at hand, but the answer came from a highly reliable source as I recall.

Re: black/white look
I always do it in post. That way, if I decided I wanted to keep the color (even if it's just one color, keeping the rest of the picture b&w) I can. If you shoot in black and white, you don't have any options later.

Re: black/white look
Keeping a color original is a good point of course. My answer only related to technical quality matters. I would love to read the related post...If the NLE processing approach is not taken into account I have my doubts on the source's reliability. The (simplified) reasoning is that, if the NLE creates the RGB data for processing out of the decompressed DV components (YUV), the reconstructed Y-only data after desaturation is the (weighted) summing up of the RGB signals which where first created out of the (full bandwidth) Y data and the (reduced bandwidth) U and V data, resulting in a partly degraded Y signal. The process difference can be compared to taking a B&W photo from a color screen, vs a photo from a screen with luma only(B&W). The latter is simular to desaturation in YUV mode in the NLE

Re: black/white look
The only reason of including ADDITIONAL gamma curves in the 100A was to satisfy the varying needs....so to my mind ALL ARE BEST if u use them at the right time. Same goes for other settings.
I think the best way is to experiment various combination of these settings, with ur cam connected to the television. for outside scenes you can take 10 sec test shots in difft situations. Seeing is Believing

Re: black/white look
Indeed gamma testing on the target display is crucial, especially when it concerns non CRT displays (LCD,DLP,Plasma) because they don't have the historically defined CRT gamma (about 2) and they all generate their own optimal "gamma". In addition, more and more high-end, non CRT displays allow to change the internal gamma settings. It would be much more logical to standardize the gamma in cams and leave the gamma settings on the display level only.

I had to do it.
