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!

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.

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!

Fringed Rue (Ruta chalepensis) UV

No special patterns appear in UV for this flower!

Helichrysum sphaerocephalum UV

Very dull in UV compared to the many color variations in visible light. Endemic.

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.

Rhus thyrsiflora UV

Not particularly colorful in visible light and even less so in UV – all dark as it is.

Pulicaria lanata UV

Dark center opposed to the all-yellow appearance in visible light – a typical Asteraceae! Endemic.

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 🙂 […]

Socotra plant 24 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!

Helichrysum rosulatum UV

The tiny flowers are dark in UV light compared to the mellow cream in visible light. Endemic.

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.

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.

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.

Lavandula nimmoi UV

Appears much duller in UV compared to visible light. Endemic.

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.

Heliotropium nigricans UV

White in visible light but quite dark in UV, and stands out in an otherwise dull/grey background in UV.

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.

Lachnocapsa spathulata UV

Yet another species with very dark flowers in UV.

Lotus ononopsis UV

This one was a surprise in UV all dark as it is, except for two tiny openings in the center.

Ruellia insignis UV

Very prominent against dark leaves and the rocks in UV. Endemic.

Socotra plant 11 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.

Socotra plant 10 UV

Mostly white in visible light but dark in UV.

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.

Campylanthus spinosus UV

Quite dark in UV and very prominent on the otherwise bright plant and rocks.

Oldenlandia pulvinata UV

Bright in visible but quite dark in UV. Endemic.

Helichrysum sp. UV

Nothing unusual in UV for this species. Please help me with positive id – leave a comment 🙂

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.

Phyla nodiflora UV

No surprises in UV light.

Caralluma socotrana UV

A mesmerizing flower in shape, texture and color which is almost completely dark in UV. Endemic.

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.

Indigofera nephrocarpa UV

No surprising patterns in UV for this one!

Socotra plant 08 UV

As with most Asteraceaes also this one has a dark center in UV.

Socotra plant 05 UV

Very interesting in UV light, as in visible it is all brightly colored!

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.

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.

Pergularia tomentosa UV

Also this plant holds no secrets in the flowers in visible light that is revealed in UV light.

Heliotropium socotranum UV

Flowers are very dark in UV. Endemic.

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.

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.

Argemone mexicana UV

What a surprise! In UV this bright flower is completely dark!

Lindenbergia sokotrana UV

Bright yellow in visible light and very dark in UV! Endemic.

Corchorus erodioides UV

Another example of a yellow flower in visible light that is very dark in UV. Endemic.

Heliotropium dentatum UV

A typical sight in UV for asteraceaes – same color in UV as in visible light, but very UV dark in the center. Endemic.

Cleome brachycarpa UV

While bright yellow in visible light this flower is completely dark and non-reflective in UV light.Endemic.

Hypoestes pubescens UV

Much more uniform in color in UV than in visible light – the white bands are missing completely. Endemic.

Euphorbia schimperi UV

No surprising patterns or colors in UV.

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.

Gurania makoyana UV

No unusual patterns in UV light.

Chapada dos Guimaraes plant 22 (Passiflora sp) UV

Perhaps equally beautiful in UV as in visible light?

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?

Chapada dos Guimaraes plant 27 UV

Surprisingly this flower is very uniform in reflection in UV compared to the nuances in visible light.

Chapada dos Guimaraes plant 26 UV

How dramatically different it looks in UV! In visible light (for us humans) it looks all yellow! Please help me identify it – leave a comment 🙂

Calliandra viscidula UV

Darker in UV compared to visible light.

Wolf Apple (Solanum lycocarpum) UV

Darker in UV compared to visible light.

Trimezia lutea UV

No surprise patterns or reflection/absorbtion in UV compared to visible light.

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.

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.
