UV photography references

This uses a Fuji S3 UVIR camera so is probably not very relevant

This uses the red channel of a modified Nikon D70S

Perhaps Raw Digger would have been of some use in these experiments for recovering the linear data ??

Dave,

We discussed these Garcia papers about a year ago. Lots of good comments to review.

 

Andrea,

Your recent posts using Raw Digger had me thinking exactly the same thing!

[DaveO]

John,

 

Thanks, that just proves that I'm going around in ever decreasing circles :)

[Andrea B.]

Well, I suppose eventually you will converge to a still point, Dave !! :)

[rfcurry]

Dave, are you feeling flushed? :)

[DaveO]

Here, from the same stable is something about iridescence

 

Is floral iridescence a biologically relevant cue in plant-pollinator signalling?

Dave :)

I didn't see the mention of UV in those papers. Sometimes the UV iridescence is quite spectacular.

....eventually you will converge to a still point.....

 

So shall we all.

[Andrea B.]

Yikes!!! We all become some sort of singularity, I suppose? :)

What's the UV signature of a Black Hole :)

Dave

[Andrea B.]

Very absorbing I think. :)

Black Hole's Disk is Flooded With Ultraviolet Light

omg that is amazing !

So it would seem to be very reflective instead.

omg that is amazing ! :D

So it would seem to be very reflective instead.

Only what is in front of the black hole (and probably what is at its back, as well, since it bends light around itself).
