thanks for the comments guys
this effect is from using Adobes new lightroom beta
the plan was to crop the balloon out with no sky (it was very flat and dull) for an abstract geometrical image
but I have found a number of presets for lightroom... a few different B&W, sepia, velvia, high contrast, HDR, selenium, split tones, etc. that I can use as starting points.
you can hover the mouse over the list and it gives a quick preview in a thumb nail, one of the velvia presets has very strong vignetting added and the photo just popped when I hovered over it. then it was just a matter of playing with the sliders to get the light right.
I only exported it as 640x428 jpeg as I didn't plan on any further editing other than sharpening and adding the border in
PS2 but ended up dodging the white part of the balloon a little to give it a little more luminance. If I was to re-edit this I would try to bring out some of the detail in the bottom of the basket as the pure black square annoys me a little
