Early on in my photography, I realized how susceptible capturing a photo is to movement. The easy answer to reduce movement is to raise the shutter speed to 1/2000th or 1/4000th of a second. Well, that all goes out the window once you are shooting in anything but full sunlight! As a proponent of low ISO shooting (having formerly loved Kodachrome 25, I come by this naturally), the last thing I usually do is raise the ISO in order to raise the shutter speed. I quickly figured out that most the movement I was seeing in my pictures was caused by my moving the camera, and not the subject moving too fast. One of the most important pieces of equipment after your camera (and maybe before new lenses), is a sturdy tripod. I have found that I need at least 2 tripods - one for travel that collapses down to an easy-to-carry size, and another I keep in the car that is large and sturdy. You will notice a huge difference in the sharpness of your photos when you start to utilize a tripod. Steady is as steady does.
