With 720+nm IR pass filter result is a nearly monochrome IR image. Set camera white blalance on sunlit grass and no PP beyond adjusting contrast is necessarily needed.
Red filter gives some colours with strong IR effect.
Chromatic aberration can be large when shooting both visible and in IR light and with IR pass filter, reflections and hoit spots in IR are common with modern lenses. Deal with it.
