Maybe with a long enough exposure, I can get some IR and UV photos without modifying my camera? We made the test. We shot our pigments checker with a Nikon D800 without any modification, such as one camera that you can buy in any shop. Then we shot with our Nikon D800 modified for UV-VIS photography. We kept the same conditions (aperture, shutter speed, UV and IR radiation intensity, distance camera – subject).
