    UV Flourescence

    In a camera magazine recently there was an article describing the taking pictures of flowers when they are illuminated by UV light instead of daylight and the different appearance they have, UV Flourescence. This is not UV photography, its just taking pictures in normal visible light of the different colours that appear when some flowers are UV illuminated so you don’t need a special camera or filters, you are just taking a normal picture albeit under low light conditions.

    I thought that it would be interesting to have a go at this so I bought a UV torch and had a look round the garden late dusk to see what I could find.

    The best result I had was from the passion flower which I have shown below. The two pics below where taken at the same time.

    As a comparison the first pic is of the Passion flower under normal ambient light, it is a long exposure (30 sec, ISO 800, F8) as it was getting dark

    This one was taken while the flower was illuminated with the UV torch so the exposure is shorter, 2 sec, ISO 800, F8

    The difference between these two images is quite spectacular and unexpected. Very few colours remain unchanged.

    There seems to be all sorts of other opportunities for this subject so you may yet get to see quite different examples!

    As always comments are very welcome.

      Interesting. I once had to take some shots of personal illuminated by UV light while wearing DPM's all very interesting and strange.

          Interesting. Insects are suppose to see lots of stuff in UV so it gives some idea what they may be seeing.

                Thanks everyone for looking and all your generous comments, they are much appreciated.

                As I mentioned, there are other things that flouresce so you may see more in this theme at some time.

                  I looked at the picture while reading the text and kept wondering what the fuss was about as it looked quite normal. Then I got to the end of the text and realised I had to scroll down. WOW! that really is a difference that justifies the experiment. I really like it. I think you also did well to get a 30 second exposure outside so sharp.

                          Very impressive. I believe that also applies to some animals.

                            Indeed, kestrels are suppose to be able to see urine trail of voles due to being able to see in UV.
