Malcom has kindly lent me some screw-on red filters with different wavelengths to simulate using a converted camera with an infrared- sensitive sensor.. The first six were taken with a 680nm filter on my Fuji X100V - not a strong infrared effect but able to easily handhold. (1-6: ISO 3200 and the noise has not been removed' 1/30th sec F8). The last image is with the 850nm giving the characteristic white foliage but even at F2 difficult to get enough light to handhold so more trials needed with tripod etc (ISO 3200 F2 1/60th).
