We are currently working on “Hauptfriedhof”, a documentary by Melanie Jilg. The film has been shot on Orwo monochrome film material and puts our color transform matrix to the test, any color abbreviation will be visible as a color tint of the whole picture. Besides that the biggest possible bit depth has to be maintained over the whole process to avoid rough color transitions or color panes in the image. A standard bit depth of 8 bit per channel enables 16.7 million colors whereas in a monochrome picture will only form 256 different shades of gray!
In this case the source material was available as HDCAM SR in 10 bit, full contrast range has been brought to the sreen: the directrice Melanie Jilg was completely satisfied with the result.
