    I just bought the S3 UVIR so I bought a bunch of different IR filters. For a regular visible light camera, I don’t see the point.

    Well, which lens do you have? Look at the lens filter diameter. Then you can go onto eBay and do a search for an infrared filter in the right diameter. Those prices are very low; just choose the IR wavelength you want to have pass through. The sensor itself has an IR blocking filter, so exposure times will be very long. I suggest around 720 nanometers; 900 nanometers and up likely will be completely blocked.

    I’m confused as to why you need an Infrared filter.

    Correct me if I’m wrong but don’t digital cameras have a filter in front of the sensor to block infrared light? I’ve seen articles about modifying digital cameras by having that filter removed so the photographer could take infrared photos.

    The Fujifilm FinePix S3 Pro UVIR is designed for taking true infrared photographs. Go to shutterbug.com and you can read the article from the April 2007 issue.
    Filters fit lenses and each lens has the filter diameter on the lens barrel or on the front of the lens. Its in mm followed by a circle with a diagonal line through it. If you have lenses requiring different size filters you can buy a polarizer for the largest diameter and use “step-up” rings so a 72mm diameter filter can be used on a lens with a 62mm filter size or even 55mm. Its almost always safe to “step-up” but you should never “step down” since using a 62mm diameter filter on a lens needing a 72mm diameter will result in vignetting (darkening of the corners of your image).

    NOTE: IMO every lens you own should have a Haze or Skylight filter installed all the time. This protects the front element of your lens and is much cheaper to replace. I only remove it when I use my polarizer. I have replaced a few scratched/damaged filters but no lenses in 36 years.
