In Michaels review he mentions in the 16 bit plugin you can select monochrome in the profile dialog box. I can find the profiles,auto(color),and none(no correction) but the monochrome selection he shows in his review is completely missing in my plugin
Need a lot more info to figure out the problem. Works fine here. My setup:
1) Win XP SP2
2) Plugin version 2.01 from Canon Europe (think it was there in 2.00 that came with the printer)
3) Load RGB file
4) Start plugin
5) Under "Output Profile" on Main page of plugin, select Auto (Monochrome Photo)
What is your setup? What version of plugin?
