I got curious one day and pulled my B&W filter kit out of my Bronica case and set it up on my Fuji S3. Switched the camera in B&W mode and started shooting at what ever. Much to my surprise, the filters reacted with the sensor in b&w mode exactly as they do with film. I am thrilled with this. Any of you who are as passionate about b&w like I am I'm sure can appreciate. A few people have said "why don't you just use channels in PS". Yeah but......Well, these are people who never saw MASH or Hogans hero's.
