Info on IR Photography using PS

I recently posted about Infrared Photography. I came across a tutorial that uses PS to mimic the effect but it requires Channel Mixer which PSE9 does not have.

I'm busy searching for alternatives but in the meantime have a look at this site:

People agree that the PS way doesn't correctly simulate true IR because PS can't easily see what light is reflected where and how.

But still, even if it's just for a bit of fun take a look.
