Thx Dave, Scott & Frank.
Mandi & Gator: Filter on all: Hoya R72 52mm filter. Lens for all: DA 18-55 "kit" lens.
1st shot, 33 mm, 30 sec @ f11. manual white balance set on some grass a few days earlier.
some extreme levels adjusted to make it so high contrast.
2nd shot: 10 sec, f/16. manual WB.
First two shots some adjustments to levels in ACR and convert to black and white using Cybia's B&WPlus filter. (they've got a bunch of freeware filter, as well as some you pay for:
Cybia - Digital Resource Studio)
3rd shot: 6 sec, f/11, DA 18-55 lens w/ Hoya filter. manual WB, also WB adjusted while importing into Photoshop via ACR 4.x, and some level adjustment too - that's really it, at most I work on the images for a minute or two in PP before I save, I'm a minimalist.
