what do I need to buy for my s1 to be able to take IR photos

I tried pointing my TV remote at my camera and it looks like the S1 is capable of IR photography.

What filter should I buy? what kind of adapter do I need to buy to attatch the IR filter?

Adaptor and IR Filter

I think all you need is a filter adaptor (Canon or Lensmate will work, though http://www.Lensmateonl​ine.com won't have theirs ready for another week or so) then you can add an IR filter of your choice. Hoya R72 is popular. See this site for lots of IR info:

The pervert side of me is intrigued

Somebody mentioned that IR passes through WET BATHING SUITS?

Just remember not to have any male crotches in your image

so, if I bought the Canon Lens Adapter/Hood set, I would be able to attatch an IR filter.

How do I know which size filter to get? Does it matter?

It's gonna accept 52 mm filters. You can't screw 58mm or 48... only 52

If you find a cheap 58mm filter, you can also use a step up ring from 52 to 58 (though it will look ugly...)

Also, if you want to just knock off a few sample shots, and have a box or two of slide film around the house. Look for an overexposed slide (pure black) and use that as quick and dirty IR filter. Most (if not all) films transmit IR light, so the pure black slide (or pure black negative) will be suitable introduction into IR imagery (it a cheap gelatin filter, so the image quality is much less than what you would get from a real filter, but ... it's free!)

Got my Hoya 52mm RM72 Infrared Glass filter today.

Does anybody have any advice as to what settings I should be using? Shutter Speed? Apature? ISO?

It's all personal taste to how you want you're images to look like, just like regular photography. You camera will meter through the filter, and that is a very good starting point. Do some at the recommended exposure, if you want raise the ISO to get faster shutter speeds. Use a few different settings, then see what you like...

Have fun with the filter. It's a whole new hidden world waiting to be seen.
