Photography Format Question

For those of you using cameras, digital or film in hopes of catching evidence of paranormal activity I have a couple of questions.

Back in the "Old Days" when film cameras were they only choice, a lot of serious investigators were using Infrared (IR) B&W film in hopes of catching a ghost/spirit. One of the reasons was due to work showcased by Hans Holzer in his book "Psychic Photography: Threshold of a New Science?". A number of the pictures could have easily been faked, or explained by double exposures using film cameras of that era, but at the same time a number of them were quite intriguing.

To use IR B&W film you had to have a decent 35mm or medium format camera that could handle high speed film. Most of the IR film was so sensitive it was rated at an ISO of 5,000 plus. Compare that to the common film speed rating of ISO 200 that you find in your local box store for 35mm cameras.

So now with the digital age upon us, and with digital cameras being uniquely sensitive to infrared light, over film cameras a couple of questions.

Has anyone done the IR conversion on a digital camera, and if so what, if any positive results have you seen?

Even if you haven't done the IR conversion, but use a digital camera to take pictures in locations are you:

Running full automatic or manual?

Using what ISO speed setting... if adjustable on your camera?

Thanks for the input.

Haven't played with the ultraviolet photography yet, though I have a camera to mod.

Check out these, I am seeing a few teams picking these up and experimenting.

Now during my investigations I always used my fuji s9000 in manual focus mode. (this eliminates the autofocus going nuts in the dark.) I would set an average distance and shoot at that. I would shoot with my flash on full power. I ran iso settings usually 400 outside and 800 inside. I never moved to 1600. I didn't want them to grainy in case I needed to zoom in. I used auto for shutter speed.

Did I ever catch anything that wasn't explainable? No
