Bristlecone stump, Patriarch Grove

Shot with the 22-megapixel Canon 5D Mark III at ISO 100.

This is an off-center subject, a bit tricker to deal with for a fast lens because the sharpness tends to fall off away from center, but also the brightness (due to vignetting) unbalances the image. Observe that the bright central area draws attention away from the large stump at lower right; this is one reason to place such subjects centrally (to emphasize them).
