I am "photocopying" some documents by shooting them with a digicam then printing. I was able to convert my images into black and white like photo copies before. These were more readable when faxed through my Mac. However I forgot which app I used. Could be Preview or Photoshop. I cannot recreate what I did LOL. Any help will be appreciated. Thanks Mad Mac
iphoto has an option that lets you edit your pictures, go to effects and there's a black and white conversion there
