    Sempervivum "hens and chicks" multispectral

    My Sempervivum ("hen and chicks") plants were flowering due to that excellent hot weather we currentlyhave here in southwest of Germany. Took photos in reflected UV and simulated bee and butterfly vision using an UV-Nikkor 105mm and a modified studio flash. Just amazing how good this lens...

    Fossilized Squid

    A while ago when Neal Larson (the guy who found T-Rex "Sue") asked me to help him with some fossils, I developed some method, used here, too... Fossilized Squid, approx. 90 mio years old, visible light image: reflected UV image: UV induced Visible Fluorescence: PS: that white patch is...

    Mica polarized

    Well this is a bit on the scientific side, sheet Mica in polarized UV and visible light, different pol. angles. If interested about the colors and why, I refer to the work of Mr Michel-Levy

    Using Cross-Polarization

    Polarization is an effective tool in photography and cross-polarization is well know to allow to suppress shine and reflections from certain surfaces. Here a few tests I have made after having been able to find suitable UV polarizers using a glass vase standing on an aluminum lab jack. Visible...

    UV Polarized Photography II

    Was doing some testing about using polarizers with reflected UV, so here a few samples presented as gifs while rotating the filter. This was shot using a modified camera with only fused silica glass in front of the sensor and the Baader-U filter (320-390nm), lens used was the UV-Nikkor 4.5/105mm...
