It all depends on your camera.
Here is a shot I took back in 2005 on a Nikon D100 camera, which has a very weak IR blocking filter. I put about 8 stops of ND filter and a polariser on the lens and was amazed to find it effectively gave me this infrared image. This is the RAW file simply converted to JPEG with no treatment at all…
I can’t do anything with it in PL until they get around to supplying the D100 module.
Here is a series of versions of a shot I took more recently with the Nikon D810 with a true IR filter on the lens, processed in PL.
Without any filter on the lens…
With the IR filter on the lens
No adjustments…
Just Ilford Delta 100 FilmPack preset…
Just adjusting the WB with the pipette on the car body…
And here is a shot taken without the IR filter and then processed in PL with the Kodak HE™ filtered (High Speed Infrared) FilmPack preset and a bit of Channel Mixer…
Finally, here is your shot, with just the same Kodak IR preset and -2 EV of exposure compensation…
