Comments to Steve B.
We have with interest noted Steve Brett's comments to our DVNR tool-box =20
integrated with colour correction systems and would like to make the =20
following comment to broaden the discussion:
We have seen colour corrections suites where the colour corrector is =20
placed upstreams of image processing tools. There might be system =20
integration reasons for that, but we believe the optimum signal chain is =20
if the colour corrector is placed downstreams of e.g. the DVNR Image =20
Processor, mainly for two reasons:
1) The colour corrector will work more optimum on a picture where there =20
is less noise, scratches/dirt, better image stability etc. This is =20
especially the case with complex colour keying as in advanced secondary =20
2) The problem with the delay introduced between operator colour =20
correction adjustments of colour correction and resulting changes on the =20
monitor would be eliminated.
One other interesting subject is the location of the aperture corrector =20
and legalising of colour space. These processes we believe should be the =20
last ones in the chain, especially if more advanced detail processing is =20
used as e.g. colour adaptive aperture correction.
