I am frequently asked what makes good composition. A tough question. A lot of the answer is subjective. For example...if you think it's good...then it is.

Also discussed are the Rule of Thirds and the Golden Mean. This article is just four pages long and well worth reading.
By the way, iStock is where I purchase a lot of my stock images for website use.
Just posted! Our new lens review of Nikon's top-end fast telezoom, the AF-S VR-Nikkor 70-200mm F2.8G ED-IF.

They also promise to: "improve the stability of AF accuracy in AI servo AF mode when shooting extremely low-contrast subjects."
