Haven't had the opportunity to share some photos in a while. Here's my recent one decided to play around with the BW settings on RX100 pretty impressed with results.
You may know this already, but a neat trick is to shoot both RAW and JPEG, but with the JPEG set to mono. That way what you see on the screen is the B&W, (so you can see what it's like in mono) but you have the full RAW (colour) file to do a proper mono conversion using something like Silver WEfex Pro
