Why Are My Photos Blurry?
There a few reasons why your photos may be blurry or out of focus and with a couple tips you can make sure your pictures turn out amazing and super sharp.
1. The object in the photo was moving.
Example: If a sprinter can run 100 meters in under 10 seconds and you are using a 1/4 second shutter speed, he or she will have traveled over 2 meters in that time. But at 1/1000 of a second, that sprinter traveled only 1 cm.
Solution: When taking photos of fast moving objects, I set my camera to a specific shutter speed, usually 1/200 or faster, and let it adjust the aperature and iso automatically given the lighting conditions. Another solution is to simply move the camera with the object before and after taking the photo. This will create a sense of motion in your photo as the object will appear in focus while the background will be blurry.
2. The camera is moving or shaking.
Solution: Use a tripod if possible. Better yet, use a tripod with a wired remote. Best, use a tripod with a wired remote and mirror lockup enabled if using a SLR. Not all camera's have this feature but it prevents the mechanical movements within the camera from causing vibration. If you do not have remote for your camera, you can always use the 2 or 10 second delay for the same effect. As in problem number one above, your shutter speed will also affect whether you need a tripod or not. A shutter speed anywhere close to one second long will be blurry unless you have a tripod.

3. Part of the picture is in focus, but everything else is extremely blurry.
Solution: Adjust the aperature accordingly. A wide open aperature (smaller number) is going to create bokeh which may sometimes be desired. However at extremes, there will be such a shallow depth of field that for example one pedal of flower may be in focus, but the other one is not. Setting a specific aperature and allowing the camera to adjust shutter speed and iso will allow you to take control and style your photo as you desire.
4. The camera is not focused on the correct object.
Solution: There are several possible solutions to this problem but they may not be successful in all scenarios. First you can try the focus lock method by pointing the camera directly on the desired object and then recomposing the picture while holding the trigger button half way. This makes it easier for the camera to find the object. Second, you can change the autofocus mode to have the camera adjust its algorithms for tracking objects in motion. Another possibility is to try and use the manual focus. If your camera has a liveview setting and you are using a tripod, you can zoom in digitally and adjust the focus manually far more accurately than you could with the viewfinder. A smaller aperature (bigger number) will create a larger depth of field and allow more of the frame to be in focus and sharp.
These are the root problems that may make your photos blurry or out of focus. Often you can make adjustments to correct for these problems and if you know to expect them, you will take great photos. Higher end equipment is undoubtedly better at creating sharper images, but there are numerous techniques to try before spending more money.
