We also made some tests on different PCs, with different scanners and with different images and we couldn?t reproduce this misbehaviour. In fact, it could be a problem with your scanner.
However, there was a bug, when "reset all" was pressed in combination with NegaFix
. A scan after "reset all" possibly showed different brigthness and colors than the preview. A workaround for this bug is to press the "auto" button in the NegaFix
expert dialog after "reset all".
