I don't do much manipulation of photos, but playing with a Luma Negative filter and some flower photos produced some interesting results. This lily was inverted after the filter was applied, to give a subtle colour change....
Very well done. The photo itself is nice, so having an invert and manipulation of it is a good idea. The odd thing about similar pictures is that they usually have a more clean look, nothing to distract, and no extra dirt. This loos nice because it does have all that i mentioned. Thanks for sharing, I give it a 9.
The lilly is excellent- but I would try to apply some sort of background, like faint blue designs barely emerging from the black. This contrast is really stark, which produces a sort of akwardness. Great work overall, thanks for the image. :D
