This might actually be the same rudbeckia flower as I posted a few days back, just bigger now and fully bloomed out, same plant at least.

Very nice. I love this flower. I am growing sunflowers in my garden, one of them is as tall as me, and will be even taller. I can’t wait for them to bloom.

Stefano, Thanks! :smile: I like how the BUG 5 looks with this set.
Sunflowers sound good. I wish I had some. I look forward to seeing yours!

Here is a channel mix of the BUG 5. UV film simulation.

I like this channel mix the best out of the 3 or 4 you just posted.
Is that BG3 or ug3?

David, Thanks! :smile:
It is Schott UG5 1.5mm (or Hoya U-330 1.5mm) + S8612 2mm stack, aka 'bee vision' stack.
Using photo #3 from the top, channel mixer in Photoshop.
Here is another example:

The channel mix is suppose to come close to simulating a UV film look, such as Birna has examples of online.

Lovely series, Cadmium.

I tend to like the BUG5 over the BUG3, but the latter is interesting.
