Selective use of color in an otherwise black and white shot is cliche -- but it is still useful because color provides a powerful spotlight on what the photographer wants to highlight.
Here are a couple of examples, one taken at Lassen National Park (Nikon D200, 18-200 vr at 18mm, f/8) and another in downtown Santa Cruz in front of a favorite burrito shop (Nikon D300, 30/1.4, f/5.6). I like their tubular tacos. Both shots were processed with Capture NX and Silver Efex using the latter's control points to selectively reveal the color of the original.
I didn't take a wide* lens to Greece last fall so I didn't get any of those mind-bending panoramas that a wide angle, a fish eye especially, can get you. Oh well. That I miss those shots so much tells me I may have to get another lens, like the Rokinon 8mm, or maybe a converter for the Nikon 10.5. It seems my shopping list is never empty.
On the other hand, I'm not really looking to add to my carry on. The iPhone's panorama function works in a pinch. Or, just overlap a set of shots by about a quarter frame then merge them later. The cost of these hand-made panoramas is in immediacy, the time spent processing, and a potentially ungainly file size, but it doesn't add to your bag.
Speaking of panoramas, here is an example of how not to shoot a panorama: the shots aren't lined up. It's not right, but I like it anyway.
*I'm gonna define wide as 10 to 12 on DX, 15 to 20 on FX.
Stepping off the ferry in Hydra the first thing that caught my eye was a blue boat. A lovely blue, it reminded me of a plastic-toy blue offered on the first-generation Miata. So I thought I'd have some fun with the blue boat set against the town as backdrop. First I cropped some sky off the top and some sea off the bottom which left just a band of each with a band of land in the middle.
