Steps to start out.

1) Ideally set WB with IR filter on. Due to darkness of filter you need to set ISO1600 & then set custom WB by pointing at grass.
2) Return to low ISO & set to shoot RAW if possible
3) Due to long exposure needed you’ll need a tripod
4) Turn to manual focus
5) Take filter off & compose shot. Put filter back on being careful not to change focus
6) With camera in Manual mode choose something like 20 sec exposure at f/8
7) Either through remote cable or self timer , take shot
Once taken , view histogram of shot. If too dark, increase exposure & vice versa
9) Voila , IR shot

Note the IR focus point is different from normal light focus point. Older lenses used to show this position, but I always put to infinity position & play it by ear.
