This is probably not a sight that most people associate with San Francisco Bay, but there you are. These cattle were grazing contentedly early in the morning last weekend as I took a little-used trail to the top of Mission Peak. There was no one else around and as I crested this rise the cattle showed no inclination to move off of the trail for me, but at least the were obliging about posing with the Bay in the background.

Someone in an online forum I read asked for example images from sharp Canon 17-40mm f4 L lenses. I posted the following images from mine. Both are 100% crops from 8MP originals shot on a 1.6x crop sensor body and, as such, they comprise a very tiny excerpt from the full original image.

(For those who are unfamiliar with the “100% crop” terminology… you are looking at a display in which each pixel of the original image occupies one pixel on your computer monitor. Another way to think of this is that if the 100% crop came from a 12MP original, the crop is roughly equivalent to looking at a tiny section of a print that is about 5 feet wide.)

The upper half is an unprocessed image. I converted it in Adobe Camera raw, then took it into Photoshop to crop and save as a .jpg. The second one was slightly sharpened in Photoshop using the Smart Sharpen tool. Pretty sharp, I’d say!

UPDATE: Here is another example of the potential for image sharpness with the Canon EF 17-40mm f/4 L lens. This is a 100% crop of a photo of some old mining equipment at Bodie, California.

The fate of his images has provoked feuds and threats, and above all, a philosophical disagreement over the nature of photography and the concept of authenticity. By MICHAEL RIPS. [NYT > Arts]

The story of this discrepancy – how a pocket-size print, sold for a few dollars in a neighborhood shop in West Africa, became a wall-size photograph that sold for $16,000 in an upscale SoHo gallery – begins in colonial Mali in the 1930’s and continues into the future: a new show of Mr. Keïta’s work opens at the Sean Kelly Gallery in Chelsea on Friday.

It is a story that includes screaming fights, a lawsuit and charges of theft, forgery and perjury. It survives the photographer himself, who died in 2001. And it touches on the broadest channels of human history, from colonialism to capitalism to revolution to race. But it also involves a conflict of the most rarefied sort – a philosophical disagreement over the nature of photography and the concept of authenticity.
