HOW TO AVOID BLURRY PHOTOS

HOW TO AVOID BLURRY PHOTOS

++++++++++++++++++++++++++++++++++

I think everyone has had a blurry photo, or way too many blurry photos.  The most frustrating thing that happens to photographers for sure.  There are a few things that causes blurry photos:

1-  You did not hold the camera still
2-  you did not focus right, or the camera did not focus right
3-  The camera is using a low shutter speed BECAUSE the light is too poor.
4-  The camera focused automatically on the background instead of what you wanted it to focus on.
5-  The aperture of the camera is not set right, because: The light is too poor.  

There are no other reasons.  When I worked in the photo store, I kept reminding people that cameras don't work quite as well as our eyes.  Too many people grab their camera and expect the camera to work as well as our eyes.  There are definitely limitations to cameras.  Once you understand that, then you can succeed in having much fewer blurry photos.  There are good tips from professionals that will back  up my suggestions.  Here is one good article to go along with what I am talking about:

I’ve heard too many new photographers telling me that they were often frustrated with blurry photographs being captured. They did not know what the reasons were, nor were they able to resolve this issue effectively.
We always understand that knowing the source of a problem can help in problem solving. In this article, I’m going to share with you some key issues that cause blurry photographs. After helping you better understand the problem, I will go on to share how to capture sharp photographs like a professional photographer.

One of the common reasons for blurry photographs is having a wrong focusing point. It’s important that you know exactly where to focus before composing the frame and pressing the shutter button. For example, when photographing portraits, professional photographers will typically focus on the model’s eyes. It’s very important that your model’s eyes are sharp and in focus. This is especially so if you’re using a wide aperture where depth of field is shallow.
Instead of using matrix focusing, 51 point focusing, or other fanciful technology, I strongly recommend using single point focus. It must be the photographer telling the camera where to focus, rather than having the camera make this important decision for us.
Although technology advances in leaps and bounds, a camera’s intelligence is still unable to read a human’s mind. The camera will not know exactly where or which area in the frame we want to focus on. Therefore, always reserve the right to make this important decision yourself.

Another key reason causing blurry photographs is having a shutter speed that is too slow. A slow shutter speed will likely cause “camera shake”, especially when you’re holding the camera without any sturdy support.
The general rule of thumb to prevent camera shake, is to have the denominator of the shutter speed 1.5 times greater than the focal length. In other words, if your focal length is 50mm, your shutter speed shall be at least 1/80 seconds to avoid blurry photographs. If your focal length is at 100mm, your shutter speed shall be at 1/160 seconds or faster.

The other get around is using a tripod for enhanced stability. This technique is good for landscape photography or photographing static objects. Pressing the shutter button may potentially cause camera shake, too. As such, it’s a good habit to use a remote shutter or the camera’s self-timer with your camera is mounted on a tripod.

When not using a tripod, ensure you are holding your camera using the correct technique. If you’re holding your camera to shoot, your left hand acts as a support and your right hand serves to adjust the settings and press the shutter button.
With the above information, I’m sure you now understand who the main culprits for blurry photographs are. More importantly, you know how to resolve the problem. With that, what are you waiting for? Grab your camera, start shooting, and have fun!

There are two things I want to add about the way we can help eliminate blurry photos.  And that is to really understand what our camera is doing.  All cameras have a shutter speed, and an aperture that controls the light and the time of the light gets to the sensor in the camera.  Tomorrow, I am going to post some details just how those work, hopefully, so you can understand that better, then you can know why your camera works the way it does.  Then maybe you can eliminate or reduce the amount of blurry photos.  If you are a professional, you can use this as a refresher course, I am sure.

Tomorrow, Tuesday, April 5th, I am going to run one more course on understanding shutter speeds and apertures.  Whether you have a camera where you can set all this, or your camera is automatic, and you just point and shoot, and hope it comes out right, this might help you to understand what is really going on with your camera.  Really worth reading.  Every one should read this tomorrow.  Even professionals could read through this and get a refresher course.
