What is "zedoShadows" Print setting?

Post by kentech »

On Mac OS X 10.6.8 + Canon i9900, in the Print dialog I see under the main popup the item Printer Features > "zedoShadows." Experiments show that varying this parameter (50% - 200%) vastly changes shadow detail while leaving highlights alone.

Where is this documented? No search on your site or this forum reveals anything about it. (And how is it a "Printer Feature"?) Seems useful in tweaking paper response to match calibrated monitor.

Hello,

zedoShadows is a new experimental feature that is not yet officially supported and not yet documented in the manual. It is to compensate for different lighting situations: visibility of shadow details depends on illumination, e.g. a details are clearly visible if a print is directly iluminated by spot lighting, but more difficult to detect when lighting is poor. Increasing "zedoShadows" will make dark areas a bit brighter and leave highlights alone. Reducing "zedoShadows" will do the opposite.
