If when you take pictures and they often turn out blurry here are some tips.
When taking a picture try to take a deep breath and hold it as the picture is taken. If you breathe while the picture is being taken, it will cause your shoulders and arms to move, thus moving the camera aswell.
Another tip is to use your elbows. If the picture you are taking is at waist height try kneeling down and resting your elbow on your knee.
One of the best tips is to use a tripod on all pictures possible. You will especially want a tripod when taking slow shutter pictures, which I will explain later.
