Bekkeblom (Caltha palustris) UV

Dette er hva som gjør UV fotografering så utrolig spennende! For hvordan ser blomsten ut i UV i forhold til hva vi mennesker ser? Vi ser bekkeblommen som helt gul, mens insekter ser en større variasjon, og denne er virkelig flott i UV! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: […]

Skogforglemmegei (Myosotis sylvatica) UV

Selv om denne blosmten er kritthvit i det synlige lys for oss mennesker, er den ganske så mørk i UV, og spesielt i sentrum, der den er gul i synlig lys. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/125 s

Vårkål (Ranunculus ficaria) UV

Dette er vårens store overraskelse hva anngår forskjeller i UV og synlig lys! Lyset vi mennesker oppfatter gjør denne blomsten altoverveiende ensfaget gul. Men i UV er den fargefordelt som man oftest ser i Asterales – mørkt i sentrum og lyse kronblad. Denne tette engen av vårkål må være som et fyrverkeri av invitasjoner for […]

Hvitveis (Anemone nemorosa) UV

Så krittende hvit som hvitveisen er i det lyset mennesket kan se, er den stikk motsatt i UV lys av en eller annen grunn. Muligens er dette som fyrlykter for de vårbestøvende insektartene! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1600 Shutter speed: 1/125 s

Fringed Rue (Ruta chalepensis) UV

No special patterns appear in UV for this flower! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Libinhania sphaerocephala UV

Very dull in UV compared to the many color variations in visible light. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Oldenlandia balfourii UV

The yellow center of the flower is dark in UV, and the white petals are also quite dark. In UV this small flower appears prominent against the greyness of the background seen here. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Rhus thyrsiflora UV

Not particularly colorful in visible light and even less so in UV – all dark as it is. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Pulicaria lanata UV

Dark center opposed to the all-yellow appearance in visible light – a typical Asteraceae! Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/80 s

Hypericum sp.

Hypericums are beautiful in UV light, as they are not uniformly colored, and this species is no exception. This species forms impenetrable thickets dotted with flowers, that seem pruned by an expert, but neither goat nor human have anything to to with this amazing growth! Please help me identify it – leave a comment 🙂 […]

Convolvulus sarmentosus UV

Yet another Convolvulaceae with identical color in UV light! I have yet to encounter one, no matter ho many different colors in visible light, that is not the same in UV! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/80 s

Libinhania rosulata UV

The tiny flowers are dark in UV light compared to the mellow cream in visible light. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Coelocarpum haggierensis UV

No surprise in color distribution in UV light compared to visible light for this species – brighter center compared to the darker outer. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/60 s

Hypericum balfourii UV

The flowers of this giant of hypericums are dark in center in UV, compared to the all-yellow in visible light. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/10 s

Socotra bottle tree (Adenium obesum ssp. socotranum) UV

What’s interesting with this landscape view of the bottle tree, is that the flowers appear same color in UV as the lichen on the rocks! Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/4 s

Lavandula nimmoi UV

Appears much duller in UV compared to visible light. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Kalanchoe farinacea UV

Very interesting in UV, as the flowers have more variations in color than in visible light in which it appears uniformly orange.. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Heliotropium nigricans UV

White in visible light but quite dark in UV, and stands out in an otherwise dull/grey background in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Dragon blood tree (Dracaena cinnabari) UV

Visiting Socotra is like going back to another time and even to another planet entirely. When visiting the only dragonblood tree forest on the island, you are surrounded by trees so unlike anything alive on Earth today, that you simply cannot wonder if you’ve gone back to prehistoric times. To emphasize the weirdness of the […]

Euryops arabicus UV

No surprise for this Asteraceae – dark in the center opposed to all yellow in visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Lachnocapsa spathulata UV

Yet another species with very dark flowers in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Lotus ononopsis UV

This one was a surprise in UV all dark as it is, except for two tiny openings in the center. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Ruellia insignis UV

Very prominent against dark leaves and the rocks in UV. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Evolvulus alsinoides UV

Almost same color in visible as in UV (although UV light is only an approximate and subjective projection, it is after all invisible to humans!), but the brighter center in visible is dark in UV, making it blander in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Asystasia gangetica UV

Mostly white in visible light but dark in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Blue pimpernell (Anagallis arvensis var. caerulea) UV

Brighter in UV than in visible light, but the center is less prominent and the yellow stamens are very dark. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Campylanthus spinosus UV

Quite dark in UV and very prominent on the otherwise bright plant and rocks. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Oldenlandia pulvinata UV

Bright in visible but quite dark in UV. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Helichrysum sp. UV

Nothing unusual in UV for this species. Please help me with positive id – leave a comment 🙂 Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Exacum affine UV

No surprises in UV, except that all the parts of the flower appear uniformly dark and that the brightest areas to us are the darkest of all. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Phyla nodiflora UV

No surprises in UV light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Caralluma socotrana UV

A mesmerizing flower in shape, texture and color which is almost completely dark in UV. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Socotra bottle tree (Adenium obesum ssp. socotranum) UV

This flower is incredibly beautiful and one of two icons of Socotra, but in UV it has no surprises – ladd rather dark, and without any patterns not seen in visible light. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Indigofera nephrocarpa UV

No surprising patterns in UV for this one! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Launaea rhynchocarpa UV

As with most Asteraceaes also this one has a dark center in UV. Aperture: ƒ/5.6 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Cucumis prophetarum 2 UV

Very interesting in UV light, as in visible it is all brightly colored! Aperture: ƒ/5.6 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Capparis cartilaginea UV

Although this flower has no pattern, or other UV specific advertising, I think it looks equally amazing in UV as in visible! It’s one of the most beautiful of Socotra’s flowers. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Socotra plant 06 UV

I have yet to encounter one species of Convolvulaceae that is not like this in UV! Either multicolored, or one color in visible, but all the same in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Pergularia tomentosa UV

Also this plant holds no secrets in the flowers in visible light that is revealed in UV light. Aperture: ƒ/5.6 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Heliotropium socotranum UV

Flowers are very dark in UV. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Aizoon canariense UV

As the petals were gone (I found none in bloom), this photo is more on the developing fruit than a true flower. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Senna holosericea UV

This flower is more interesting in UV, as the veins and the center has a darker more pronounced color compared to the more or less all-yellow in visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Argemone mexicana UV

What a surprise! In UV this bright flower is completely dark! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Lindenbergia sokotrana UV

Bright yellow in visible light and very dark in UV! Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Corchorus erodioides UV

Another example of a yellow flower in visible light that is very dark in UV. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Socotra plant 02 UV

A typical sight in UV for asteraceaes – same color in UV as in visible light, but very UV dark in the center. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Cleome brachycarpa UV

While bright yellow in visible light this flower is completely dark and non-reflective in UV light.Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Hypoestes pubescens UV

Much more uniform in color in UV than in visible light – the white bands are missing completely. Endemic. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Euphorbia schimperi UV

No surprising patterns or colors in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Jatropha unicostata UV

Also this species is dark in UV with no pattern or markings that should suggest advertising to certain pollinating insects in UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 800 Shutter speed: 1/100 s

Gurania makoyana UV

No unusual patterns in UV light. Aperture: ƒ/11 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/60 s

Passiflora mansoi UV

Perhaps equally beautiful in UV as in visible light? Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/60 s

Chamaecrista sp UV

Perhaps even more beautiful in UV as the dark center is contrasting the bright petals, opposed to all yellow we humans see? Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/60 s

Chapada dos Guimaraes plant 27 UV

Surprisingly this flower is very uniform in reflection in UV compared to the nuances in visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/60 s

Adenocalymma peregrinum UV

How dramatically different it looks in UV! In visible light (for us humans) it looks all yellow! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Calliandra viscidula UV

Darker in UV compared to visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Wolf Apple (Solanum lycocarpum) UV

Darker in UV compared to visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Trimezia lutea UV

No surprise patterns or reflection/absorbtion in UV compared to visible light. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Chapada dos Guimaraes plant 01 UV

What a big surprise that this bright flower in visible light is completely dark in UV! Not even a lighter and a darker region. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Aspilia sp UV

In UV the all-yellow we humans see, is not at all present. The size and shape of the dark centre can in many instances be a key component in identifying species that are very similar morphologically. Aperture: ƒ/5.6 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/80 s

Pantanal plant 48 UV

Perhaps even more beautiful in UV? There is no mistake in the plant’s advertising to the pollinating insects – the tidbits are at the centre of the bright petals! Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 1000 Shutter speed: 1/100 s

Pantanal plant 47 UV

In UV I think this flower is as beautiful, perhaps even more than in visible light! The patterns, and shades are at least as intricate and detailed in UV as in visible light. That’s what I find so exciting – I never know from my visual standpoint whether or not the flower is a beauty […]

Sphinctanthus sp UV

Not a striking difference in color in UV. In visible light the color is even more uniform – creamy white. But not surprisingly, the stigma in the center of the flower has a distinct darker color than that of the petals. The same goes for the anthers, the flat & oblong segments resting between the […]

Macroptilium lathyroides UV

In visible light this is a very dark flower, but in UV lots of light is reflected, and seen here as yellowish and without any darker areas around the center of the flower which is where the insects should be directed if the plant is to be pollinated. With this very unusual design I wonder […]

Ludwigia bonariensis UV

In the light we humans see, this flower is uniformly yellow, with a hint of variance in the centre. In UV this variance is very dark and different from the outer areas of the petals. This is what the pollinating insects see. It’s like the bull’s eye of a dart-board. If you come here you […]

Åkergull (Erysimum cheiranthoides) UV

I lyset vi mennesker oppfatter er åkergull ensfarget gul, og kan ligne veldig på berggull. Men i UV lys er det en stor forskjell, da det er mørkt i sentrum av blomsten. Disse plantene er svært små utgaver av arten, og vokser på grusveien til en av naboene. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: […]

Skogsalat (Mycelis muralis) UV

I UV lys er den ensfarget gule skogsalatblomsten langt fra ensfarget, og det er det som gjør det så spennende med fotografering i UV lys, for da kommer de unike signaturene frem som vi mennesker ikke ser. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/160 s

Mørkkongslys (Verbascum nigrum) UV

I UV lys er kronbladene lyse og pollenknapper og tråder mørke. For menensket er UV kanskje en blek kopi av de nøyanser vi ser i vårt begrensete del av lyset, der oransje og hvit trer frem. Om vi kunne se UV i tillegg ville vært et spennende skue – heldigvis har vi teknologi som kan […]

Vindelslirekne (Fallopia convolvulus) UV

Ingen overraskende mønstre eller farger i UV. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/160 s

Veikarse (Rorippa sylvestris) UV

Veikarsen ser nesten identisk ut i UV lys som i synlig lys, men pollenknapp, arr og dekkblad er mørke. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/160 s

Gjerdevikke (Vicia sepium) UV

UV signaturen til gjerdevikkeblomsten er egentlig ikke så ulik den i det lyset vi mennesker oppfatter – mørke årer på lys bakgrunn. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/160 s

Takhaukeskjegg (Crepis tectorum) UV

For mine øyne er dette en helt gul blomst, men atter igjen kommer det spennende nøyanser frem i UV lys og spesielt rundt sentrum av blomsten. For mange vil dette kanskje se ut som et kunstnerisk uttrykk, der jeg har fremhevet kronbladet i et ellers mer eller mindre svart og hvitt miljø. Aperture: ƒ/8 Camera: […]

Strandnellik (Armeria maritima) UV

Ingen overraskelser i fargefordelingen i UV lys – like ensfarget som i synlig lys. Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/125 s

Hårsveve (Hieracium pilosella) UV

Dette var en stor overaskelse! I UV er denne blomsten helt mørk i motsetning til i det lyset vi mennesker oppfatter, der den er lys, altså gul. Mange kurvplanter her mørke og lyse deler i bomsten, men hårsveven er kun mørk. Hvorfor? Aperture: ƒ/8 Camera: NIKON D7100 Focal length: 105mm ISO: 2000 Shutter speed: 1/125 […]

Krattmjølke (Epilobium montanum) UV

Ingen store overraskelser i UV lys – slik som eksempelvis potentillaer og skjermplanter, som ofte viser helt mørke områder vi ikke finner igjen i lyset vi mennesker ser. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Skjermsveve (Hieracium umbellatum) UV

Skjermsveven er en sikker matkilde til insekter til langt på høsten og jeg passer på å vanne de så de blir frodige og fulle av blomster. Som med så mange kurvplanter, er også denne arten veldig forskjellig i UV. Faktisk er den flottere i UV enn i det synlige lyset der den fremstår som ensfarget […]

Flerårsknavel (Scleranthus perennis) UV

Svært mørk i UV lys. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Rød jonsokblom (Silene dioica), spp. alba UV

Dette er en krysning mellom rød og hvit jonsokblom, og i for mennesket det synlige lyset er blomsten rosa og hvit, mens den i UV er helt ensfarget. Det interessante er at både den helt hvite og røde jonsokblomsten er lik i UV. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Prikkperikum (Hypericum perforatum) UV

Som mange gule blomster (slik vi ser de) er også prikkperikum mørk i sentrum i UV lys – pollenknappene er også mørk, og danner dermed en kontrast til den lyse bakgrunnen på kronbladene – viktig for insekter. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Ryllik (Achillea millefolium) UV

Ryllik er en kjent og kjær plante som vokser overalt i området, og står i blomst til langt på høsten. Den kommer i rosa variant også, men det snodige er at i UV er den i samme farge som vist her enten den er hvit eller rosa for det menneskelige øyet. Camera: NIKON D7100 ISO: […]

Sølvmure (Potentilla argenta) UV

I UV lys er mureblomsten svært forskjellig fra det ensfargete gule vi ser. Ingen tvil om hvor godsakene er for de som flyr forbi og kan se i UV. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Torskemunn (Linaria vulgaris) UV

Veldig mørk i UV lys. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/100 s

Smørbukk (Hylotelephium maximum) UV

I UV lys er smørbukken variert og spennende – kanskje mer enn i det synlige lyset? Det er spesielt humler og bier som besøker smørbukken, og er en siste stabile matstasjon før frosten for mange insekter. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/20 s

Stemorsblomst (Viola tricolor)

Mørk i UV lys – ingen av de lyse områdene i synlig lys er det i UV. Camera: NIKON D7100 ISO: 2000 Shutter speed: 1/160 s
