Faking Black & White...

I keep the Samsung TL500 set up to record two files with every shot. The camera records one in RAW format, which for Samsung uses the ".SRW" file extension, and one fine quality JPEG. You can set custom color balances for the JPEG like Soft, Vivid, Forest, et cetera. It took me a little bit of scrolling and testing to figure out that "Classic" was Samsung-speak for "Monochrome".

So that's what I use: One RAW file is recorded and a monochrome JPEG. Being as this is a 2010-vintage pocket camera, it takes it a hot minute to write that 24MB .SRW file. If you just wanted to turn the camera on and pop off a quick shot or two then shut it back off, you'll be waiting a few seconds for the green "Busy" LED to stop blinking before it'll retract the lens and power down.

The Classic setting gives you a pretty stark and contrasty B&W effect.

Here's what the scene actually looked like, via the processed RAW file:
