The previous post was supposed to be longer, but I'm having some issue posting multiple images from Flickr to HC. Yes, the irony of that statement is not lost on me.
The stream at the edge of my property. I spent considerable time framing this shot. 35mm F/2 at F/8, 1/60, ISO200.
It's just a bunch of trees. Converted to black & white in Photoshop using a high contrast blue filter, then duotoned. I also tweaked the curves a bit and then cropped it to 5:4 (which has been my favorite aspect ratio for a decade now.) The vignetting is organic, and not done by a PS plugin. It's an artifact of how the EF 50mm F/1.4 USM transmits IR. F/8, 1/100 ISO 160.
17-40L at 17mm, F/7.1, 1/100, ISO50.
17-40L at 19mm, F/6.3, 1/80, ISO50.
Moar later.
