[UV] Spring flowers in UV ultraviolet light - yellow overdose

Just the perfect sunny spring day today and a chance to capture some yellow flowers, that also come out yellow in UV in my standardized false color scheme - as they reflect UV around 360nm. I'm showing matched image pairs (VIS, UV).

This UV image here also uses my standardized false UV color normal + high intensity palette:



1) Oregon grape (Mahonia aquifolium)




2) Dandelion (Taraxacum officinale) and Daisy (Bellis perennis) and Ground Ivy (Glechoma hederacea)




3)Lesser Celandine (Ranunculus ficaria)




4) Yellow Anemone (Anemone ranunculoides)




5) Dandelion (Taraxacum officinale)




6) Wild Tulip (Tulipa xx) and Pheasant's Eye (Adonis vernalis)




Pretty amazing what nature does to attract pollinators!


Stay tuned, more will follow on that fascinating subject...

[FL] Another Bouquet: Gerber Daisy, Hyacinth, Roses,...

Here a UV induced visible fluorescence shot of another flower bouquet using Nichia 365nm UV LED and a 400-700nm UV/IR Cut filter.

and here for comparison the white light (5600K LED) shot



closer to see more details...





Well and here as another comparison, what happens when a Xenon flash with UV filter is used to stimulate fluorescence.

UV Xenon flash, but that leads to IR + red contamination as may be seen here:



and here now using a BG filter to compensate for that



but in overall comparison, the Nichia UV LED wins hands down IMHO!


Stay tuned, more will follow on that fascinating subject...
