Most of my IR shots are taken with modified Bayer cameras, or normal cameras when I want slow shutter speeds but there is one other style of IR shooting I've tried occasionally. Pseudo areochrome, mimicking the results of the old Kodak colour IR film (where IR is recorded in the red) Using a Foveon sensor this becomes quite easy giving results like this SOOC:
seafront garden aerochrome small by Mike Kanssen, on FlickrThis was taken using one of my antique Sigma SD14 bodies, with the 'dust filter'/hot mirror removed (a <2 minute DIY operation), then adding an X1 filter & using fluorescent WB. I've not had any success using this cameras RAW.
Foliage was the normal colour to the eye, & the clothing showing in RED is visually black.
No post processing beyond resize done on this one but I sometimes have to tweak hue slightly.
It should be possible to use the same camera for monochrome IR with a suitable external filter, but having far more modern adapted cameras available I never really tried. The SD14 was released in 2006 so it's getting on for 15 years old!
