In this example I transcoded the footage in Cineform's HDlink to high bit rate Cineform intermediate files. Then I turned the contrast down to 0.542 on both files in Firstlight. I then exported using Microsoft expression encoder to 35 mbps MP4.
Download the original file I uploaded and view on an HD monitor to compare. Watch the shadows and the apple for example to spot clear differences. N.B - this is with a none moving target - things get clearer if you have a moving target - the high bit rate stuff holds together much better IMHO.
