Factors That Cause Photos to Become Blurry

Factors That Cause Photos to Become Blurry – Photos that are out of focus, blurry, or blurry in English are annoying and unpleasant to look at, especially if the blur is the main object or subject of the photo. For this reason, a photographer must understand the causes of blurry photos because that way the photos can be sharp and focused so that they are pleasing to the eye.

Many photographers, both beginners and advanced, often make the background blurry. Indeed, this kind of photo is very popular because it makes the object in the photo stand out more. In addition, photos become more pleasing to the eye.

What are the factors that make the background of a photo blurry?

1. Lens aperture (Aperture)
By using a large lens aperture (f/2.8 or greater like f/1.4), the background becomes more blurred.

The bigger the opening, the smaller the number.

2. Lens focal length
The larger the focal range of the lens used, the more blurred the background will be. Example: The background of a photo taken with the focal range of a 55mm lens is blurry than when taken with the focal range of an 18mm lens.

3. The ratio of the distance between the subject of the photo and the camera and the distance between the subject and the background.
The closer the camera is to the subject of the photo and the farther the subject is from the background, the more blurred the photo will be.

Example: If the distance from the camera to the subject of the photo is 1 cm, and the distance from the subject of the photo to the background is 20 m, it can be ascertained that the background becomes very blurry. This is because the ratio / distance ratio is very large.

Conversely, if the distance from the camera to the subject of the photo is 20m, and the distance from the subject of the photo to the background is 1 cm, it can be ascertained that the background becomes very clear / sharp.

4. The size of the sensor in your camera.
Camera sensor sizes vary, the bigger it is, the easier it is to blur the background. A cell phone camera or pocket camera has a relatively small sensor size compared to digital SLR cameras. In digital SLR cameras, there are several types of sensor sizes.

The smallest to the largest are: Four thirds (4 to 3 ratio), there are crop sensors 1.6 (Canon), 1.5 (Nikon, Pentax, Sony), there are also full frame (Nikon, Sony) and medium format ( Phase One, Leica S2).

5. Hand swaying/moving
When you’re shooting, get into the habit of not moving until the photos are displayed on the monitor/LCD screen.

Why? Because digital cameras take a while to process the data sent through the lens and sensor. A swaying or sudden movement of the hand causes the lens to shift, even slightly, and incorrect data is sent to the processor.

The slightest movement or hand holding the camera will ensure the result is almost certainly a blurry photo.

6. Moving objects
The camera is already on a tripod and is stable, will the photos not be blurry? Maybe not.

If the object suddenly moves, the blur will definitely be present as well. The explanation is the same as a moving hand because the focus of the lens changes and shifts.

7. Light source is lacking
Cameras need enough light to take good photos. Lack of light sources will require the correct setting of the exposure triangle so that the problem can be solved, namely by changing the ISO, Aperture (Shutter / Diaphragm), or shutter speed (speed of opening the shutter).

Errors in settings, such as a shutter speed that is too slow will cause blur to appear in the photo.

8. Aperture is too narrow
Blur may also be caused by an error in using the aperture. You set the number to a small number, such as f/1.8 or f/2.2. These numbers show you ordered the camera so that the part that is in focus/sharp in the photo area is narrow.

This makes it difficult to focus, especially if the object is moving.

9. Forgot to turn off manual focus mode
This one often happens to DSRL or Mirrorless camera users where the lens has two focus modes, AF (auto focus) or MF (Manual Focus). The way to change it is by sliding the button to the required mark.

Not infrequently after using MF mode, we forget to return it to AF. The result is a blurry photo.…
