Let us face it, we all have gone thorough this. Getting blur photographs is the biggest frustration for all photographers. The reason for blur or soft photograph is not the gear but actually our shaky hands.
To get to the basics, we need to make sure that you are focusing on the subject and the camera is held still at the time of taking the photograph. This means using both hands for holding the camera, keep the camera close to your body, support yourself with some solid object and hold your breath and shoot. But, it is easily said than done.
The easiest way to achieve sharp pictures is to use a tripod. But, carrying tripod always is not possible and at times an irritation.
So, when you are taking handheld photographs, the best way to control camera shake relates to the shutter speed setting in your camera. There is a recommended minimum shutter speed for taking pictures. The thumb rule is that your minimum shutter speed should be 1/(the focal length).
So if you shooting at 300 mm focal length, then your minimum shutter speed should be: 1/300 sec.
If you are shooting with a cropped sensor camera your minimum shutter speed should be 1/(double the focal length).
This should ensure that your photographs are sharp and without blur.
I would love to hear your experiences on this topic.
