Experiment at Sydney University on my D7000. Digital multiple exposure, with a blue Hoya Pop Colour Filter.
Looking toward the city from the Quadrangle.
FOV: 5" wide.
Zinc chloride from pennies and calcium chloride from limestone (digested by muriatic acid) was combined with sulfur, NaCl and 3 drops of MnSO4 sol. This was melted with a MAP gas torch.
Contains:
ZnS:Cu (FL Green >UVabc)
ZnS:Mn (FL Orange >UVab)
CaS ?
Shown under UVc light.
Key:
WL = White light (halogen + LED)

An experiment - and a short break from the gloom of the winter Gormleys ...
I recently found an interesting link on *kday*'s page to the Orton technique. It looked like a nice soft effect so I thought I'd give it a go. I know I haven't got it quite right yet, but I think it might be worth experimenting more.
But I'm still not sure ...
What do you think?

I'm really not sure about this picture and so I'd be massively grateful for your constructive comments. Does it work? Is it under-exposed? How would you improve it?
If you have a moment, I really would appreciate your thoughts as I feel I'm in completely new territory here...
Many thanks,
Tom.
Many thanks indeed to everyone who contributed to this really useful discussion - I found it immensely helpful. Thanks!
... I downloaded this free texture a few days ago and forgot where I found it. If you recognize your texture... please tell me so I can give you the credits for it :-)

"Bodegón"
"La naturaleza humana es mutable, falible, cruel, pero también la más grande de todas las historias contadas"
W. Somerset Maugham
Datos Técnicos:
Exposición: 0,02 sec (1/50)
Aperture: f/4.5
Lente: 29 mm
Velocidad ISO: 100
Tendencia de exposición: 0 EV
Producción: No muy complicada. Intentar que la iluminación me permitiera definir cada pétalo de la Rosa y crear una definición propia, utilizando un rebotador casero.
¿La quieres ver más grande?
Usually cats don't feed flower, but in this time it seems to be. I also used a special cross-processing effect that I never used before (also this an experiment) ;).
Enjoy!
