I have a strange question...(yes I know I seem to have lots of 'em!lol) I have started to post some black and white photos..but on my PSP it calls them "greyscale" is that a true black and white change over or is that ONLY grey? and if its only grey, how do I change them to black and white? My Nikon has a setting for it also..but I have some older photos I would like to turn into B&W...can anyone tell me please? thanx
