    Hi,
    I managed to pick these 2 flowers today which look like the dandelion. BTW, these are stacked images from 2-3 shots to ensure nearly all the flower is in focus.

    Very nice, crisp and clear, especially the Hawkweed images look great!

    P.S.: the UV light seemingly comes from another angle than the visible light?

    P.P.S.: what causes these visible structures in the background? Isn't your backdrop smooth?

    The visible light comes from 2 fluorescent tubes built into the light studio, so the light comes from all reflected surfaces. The UV source is my Quantum T5DR which is angled downwards and backwards, and the light is distributed by the Quantum standard reflector. I do have a small aluminium reflector at the bottom to reflect some light back up to even out the shadows. The background is not entirely smooth, but the effect seen may have been exaggerated by the stacking process.

    Guess that explains it, thanks Boon!
