In Secret to Sharp Photos, I talked about holding your camera steady and linked you to a video to an advanced way to hold a camera when dealing with low light. I did not go into too much detail on how to hold a camera steady for normal shooting.
Like anything in life, you start with the basics and build your skills upon them. A good friend of mine, Tim Devine of The Magic in Pixels, spends a lot of time in his workshops and meets demonstrating to people how best to hold a camera. I think many people feel it is not that important. Believe me, it is VERY important. The first thing I ask when people tell me they get blurry photos is how they hold their camera. They seem a bit bewildered by the question but just by holding the camera correctly can and will cut down on most of those blurry photos.
I ran across an excellent article from the Digital Photography School which goes into detail on how to hold a camera called, How to Hold a Camera. See, basic and direct. Whether you are a beginner, intermediate or advanced shooter, it is a good idea to review and practice the basics from time to time. It will help you to make beautifully detailed and sharp photos.
