Eryngium ‘Blue Star’ in Ultra-Violet Fluorescence

I have just finished catching up on the processing of the UV fluorescence photos that I have taken this month. This post shows 2 examples of Eryngium ‘Blue Star’ which is a type of ‘thistle’ with blue colouration – these come from my wife’s small garden.

For both sets I am showing a comparison ‘slider’ showing the daylight flash and UV fluorescence together then a composite picture showing on the one image the 2 versions of the photos.

Example 1:

Eryngium Blue Star in daylight flash
Eryngium Blue Star in UV fluorescence

Eryngium Blue Star composite showing both together

Example 2:

Eryngium Blue Star example 2 in daylight flash
Eryngium Blue Star example 2 in UV fluorescence

This is one plant where I find the daylight version is better than the UV fluorescence!
