[UV] White Clematis in ultraviolet light using a quartz Focal Reducer lens

More shots using my white Clematis hybride I recently got. Here now using that before presented Spectrometer Quartz Fluorite Achromat f4/84mm lens with a 0.42x quartz Focal Reducer lens to make it a f1.7/35mm lens.

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



White Clematis in UV:


and in visible light (VIS):


Differential VIS-UV:


The VIS-UV differential clearly shows, that despite the Focal Reducer, still hardly any focus shift is present.

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

[BV] White Clematis in simulated Bee Vision

Same white Clematis hybride flower as shown before in the UV ultraviolet shot, but this time the comparison between normal visible light and simulated bee vison (UV, B, G) as been can only see (ultraviolet, blue, green)

Simulated Bee Vision (UV, B, G):


normal visible light shot:


So obviously also in the simulated bee vision shot it has some dark patterns, as the stamen and stigmata are quite dark, but the flower petals show some UV reflectance. There are also some darker structures visible in these petals.

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