Gazania colorful UV

It’s the bg swirl!

Was it sharpened?

I am wondering how it would look untouched by edge enhancement!

Asher
No special sharpening applied, only to compensate for resizing a little bit.
That Quartz lens stepped down is quite sharp in ints center!

Here is the whole series with various aperture settings:

That rapid sharpness falloff outside the center area and towards VG, BG gives that 3D impression

Here same flower, same lens, at different angle:

It looks like you chose the second of the examples you referenced. I like that balance as one doesn’t want the bg too harsh or too soft!

BRW, “contra lucem” is a term more associated with ecclestiastical debate in Latin. So you mean “back lit” it do you mean “reflected light” or what.

Is this more of a poetic term, or commonly used in academic Spectral investigations with biological samples?

Yes, that's the one I selected, exactly because of that - it is balanced for me.

For me, it is "shooting against the light", was discussing this with an Italian
photographer friend many decades ago and he actually tought me this term.
I was using "contra lux", but he had corrected me it should be "contra lucem"
