 how to convert digital image to infrared
Just shift the green channel to the blue channel, shift the red channel to the green channel, and use the brightness/luminosity/grey values from the actual near-IR iamge to replace the red channel.
Beyond this point, I recommend studying some physics or engineering texts to learn what these films actually capture and going from there as a pseudo conversion from a color image using PS will require knowledge of the image content to be used to make a decent conversion.
Use the Channel mixer in PS, set it to Monochrome and use full Red, and reduce Blue and Green to taste, then adjust Constant.
