In this image the main light is a Pulso-G with an UV attachment. The UV attachment is blocking the visible light, so it is only the UV light which is reaching the subject.
To optimise this effect, it is important to work without the UV-protecting glass which is blocking the UV-light.
What we get to see on the image is something our eyes can't normally see. Unlike humans, bees can perceive ultraviolet light. This “bees vision” makes finding nectar much easier.
In the flowers and plants I shot, it is especially the part with nectar and pollen which get very bright and show colours that are not corresponding with what we see with the visible light. With the UV light, some of the white plants and flowers get bright blue and violet.
I did not only use UV light illumination - I added some light with a Picolite and a projection attachment, which was shining on some of the leaves in the back of the set-up.
I used the projection attachment because I was very selective in what I wanted to illuminate, and it allowed me to be very precise.
As a result we have a mixture between UV light and visible light, the balance between how much UV and how much visible light is of course a matter of taste.
The image has been taken with a full frame DSLR camera and a focal length of 105 mm. The exposure time was 1/125s and the aperture f/14, with ISO 200.
