Typically, the mistakes from beginner photographers are miscalculated shutter speed (shutter speed) so that the image becomes blurry.
There are two main factors that make the picture become a blur.
The first is setting your shutter speed is too slow compared with the range of your lens (focal length).
In general, if you want your images do not blur due to hand-shake us, the formula is 1 / range lens focal.
For example, if you take photos in the 100mm focal range, then you need a shutter speed of 1 / 100.
This formula applies when you use the full frame sensor camera.
For existing Digital SLR camera in our market, most of them are using smaller sensors.
These sensors vary from one camera to another.
But in general, Canon using 1.
6x, Nikon, Sony, Pentax using 1.
5X and Olympus using 2X.
With this variation, the calculation becomes a little more complicated.
Back to the example earlier where you decide using 100mm focal range on the Canon Rebel camera that uses 1.
6x, at least you would have to use 1 / 160 to prevent blur.
(Found from 100mm x 1.
6).
this is because the greater the focal range.
Why you should use a faster shutter speed when the range of focal greater than normal focal range?, It is because the sensor more sensitive to capture vibration.
The second factor is that you photograph objects moving too fast, so that the shutter speed must also follow the rapid motion of the subject of the photo.
For example, to freeze the movement of people running a basketball player, you need a minimum of 1 / 500.
For dancers and singers, usually use 1 / 200.
And to photograph people who do not move usually use 1 / 60.
Joe Decker from Photocrati blogs photos introduce new factors sensor pixel size that affect the blur.
He said the same sensor size cameras, but high-resolution image require a faster shutter speed due to the small size of the pixels that are more sensitive in detecting vibration.
If this theory is correct, then a size 15-megapixel camera will be more prone to blur rather than a size 6 megapixel camera.
How to prevent There is also a technology in the camera or lens that is intended to prevent blur.
This type of technology is divided into two categories.
The first was made in camera, the other inside the lens.
There are many variations of the name of these technology.
Like the Image Stabilization (IS) or Vibration Reduction (VR), Steady Shot (SS), Shake Reduction (SR), Mega OIS, Optical Stabilization (OS) and Vibration Compensation (VC).
Everything works with the same function, just a different term.
This technology could help you but can not help totally.
For example, previously you must use 1 / 200, but with the help of this technology, you can use 1 / 100 or 1 / 60.
This technology also can not prevent blur when you take photos of people or things that move fast.
Another thing that can be used to prevent blur are the technique of holding the camera and breathing techniques.
By holding the breath while taking a picture, and positioning the body leaning on the wall, can help reduce the vibrations that produce blur.
