UV explorations

I've been out and about, taking plenty of UV photos. These are such a grab-bag, I was not sure where to file them. (Andrea - For the flowers, I hate to make a formal post with my photography skills still so newbie-ish. I don't want to adulterate the database with inferior shots compared to what is currently in there. Also, you have these species already.)

(Apologies for the camera phone, but I do not yet own a UV/IR cut filter.)

This was interesting because the UV "bullseye" was inverted with respect to the visible image! I haven't seen that before.

It looks like the Noflexar's background bokeh is distinctly negative, which results in a hint of line-doubling on the branches in the last photo. Foreground bokeh may be neutral or weakly positive, judging from the petal tips in the second photo. I would be curious if its visible or IR characteristics are any different.

Andy, don't worry about "adulterating" the database if you would like to post a botanical example sometime. Some of my old D200 efforts are truly awful.

 

This tulip is definitely IS interesting with its reversed bullseye UV signature.

 

And Hello-Andy-in-UV !! Cool shot !!

Clark, that was interesting to me about the Noflexar bokeh. I've seen line-doubling like that before in other lenses.
