Take pictures that are not blurred

After taking a picture, I checked the camera screen, canvas prints and the composition, color and even the expression of the Model all looked quite perfect. When I went back to the computer, the image seemed to be in a third kind of contact. Could I only beat my heart to express sorrow, but I didn't know how to prevent this situation?! As the saying goes, "more haste, less speed", no matter how great the scene is in the photo, if it is not carefully sloshing, the value will be reduced. Here's how to take a photo without blurring!

What are hand quakes?

There are two possible reasons why a DSLR accidentally produces a blurry, foggy image. Although the photographer focused away from the target, canvas photo prints cheap resulting in a grayish, blurry image, there were some areas of focus that were clear on closer inspection. For photos like this one that don't focus properly on the subject, you can get a clear picture by using the correct method you learned the day before.

When photos look gray, a second possible cause is hand tremors. If the whole picture is out of focus and appears to shake, it is the shaking of the hand during the shooting, which causes the camera to shake. Why does this hand shaking happen? Because we press the shutter button after the photo is open for the duration of time by the light into the image sensor received. But what happens when the camera shakes when the shutter opens? A blurry photograph, of course. Since this happens when the shutter is open, large canvas a fast shutter speed is less likely to occur, and a slow shutter speed is more likely to occur.

Handshakes caused by shutter speed

So when will hand tremors occur? The first reason you can think of is shutter speed. Even if you shoot the same object with a fast shutter speed, you are less likely to get a hand shake, but if you slow the shutter speed, you are more likely to get a hand shake. A combination of aperture, ISO, and timing can cause shutter speeds to slow down when shooting at the same object.

Methods to reduce hand tremors

Hand tremors occur when you slow the shutter speed or use a long lens. To avoid them, it is important to raise the ISO value so that the shutter speed is fast enough to shoot, or to be careful not to shake the camera.

Hand shock caused by lens focus

Hand tremors are not only caused by shutter speed, but also by focal length. Try installing a standard lens on a DSLR and turning the zoom ring to set the focal length to 18mm before shooting indoors. If you are taking pictures indoors, generally you will see a shutter speed of 1/15~1/30 second, so you can take a clear picture without hand shock if you take pictures at a wide Angle of 18mm focal length.

In the same scene, use the same shutter speed at the wide Angle end to shoot, but turn the lens to take a picture at 55mm in the telescopic state, and you will find that the phenomenon of hand shaking does not occur in the wide Angle lens, but appears after shooting with the telescopic end.

Simple formula to prevent hand shock

As mentioned earlier, hand tremors often occur when shutter speeds are slow and long lenses are used. In order to get a clear picture, the formula for preventing them is important. For example, if I am using a lens with a focal length of 18mm, hand tremors will not occur if I set the shutter speed to be 1/30 of a second faster than 1/18 of a second, but they will occur if I use a slower shutter speed of 1/15 of a second. In addition, if the focal length is 55mm, 1/30 of a second less than the focal length value, the image will be blurred. Therefore, it must be set to more than 1/60 of a second in order to take a clear picture.

While hand tremors seem to occur only in indoor photography with a slow shutter speed, they do occasionally occur in bright outdoor shooting with a telescopic lens. So whether you're outdoors or indoors, make sure you use a shutter speed that's higher than the focal length of your lens, floating canvas frame so you can get a clear picture without wobbling.
