If you can get your hands on a Sony V1 point and shoot camera, it has built in infrared button. Just get an adapter to put the r72 filter on, add a nd8 filter also to cut glare, and shoot away.
The processing is another story. It's alot of fun using the saturation lever to add color back in. Or you can alter them to B/Ws by clicking on Greyscale and then adding some contrast, the simplest way when in a hurry. The fun part is you never know what you will have until you get home. ;~)
