Try to observe the latest photos of your DSLR camera produced? Is the photo looks no dark spots consistent from one photo to another? Is it always the same spot where? If the answer to both of these questions is YES, meaning your camera sensor dust infestation. In this article we will learn to detect the presence of dust on your DSLR camera sensor.
How to Sign Up Sensor Dust?
Dust on the sensor is a common thing when you’ve long had a camera. How dust can get stuck in the camera sensor? There are several ways to enter into the sensor dust:
The mechanism that rotates the lens while zooming and focusing. When spinning dust in the lens can be sucked fall to the camera sensor.
Since the round on two points above the mean friction elements, may appear flakes and splinters fell into the sensor.
If we have more than one lens, dust likely to fall during the process of changing lenses.
Dust or dust is actually not only contaminate the sensor DSLR cameras, there are some other elements that may actually be contaminated, but the worst is censorship because if the sensor is dirty, dirt will always appear and visually look at each photo, especially when you use the aperture small aperture, F/10 down. Dust on the lens is relatively easy to clean while the dust on the lens need further treatment when dust cleaning feature in the menu on the camera did not succeed in removing it.
Some characteristics of the photo with sensors contaminated by dust:
The size and appearance of dust particles changes with aperture. If you are using a large aperture, the possibility of dust will not be visible. But when you use a small aperture, dust immediately visible. Such a small aperture F/10 down: f/11 – f/22.
Dust particles are always seen in the same place
To determine the presence of dust on the sensor, we have to observe from photos
Examples of dust on the sensor can be seen below:
How to detect it Right Now?
Try to follow the 10 steps below:
Set the camera in Aperture Priority position
Set metering mode in position Matrix / evaluative Metering
Set the ISO at least 100 or 200 positions
Turn off Auto ISO
Turn off the Autofocus and Manual Focus lens position
Set in the position of the smallest aperture, eg f/16 or f/22
Get out of the house and try to picture the sky, especially when the sky is bright blue. If not possible, look for the white paper and then zoom out until the paper fills the entire frame and take a photo.
Now observe the images on the camera’s LCD or a computer monitor if you’ve moved it to a computer, zoom and scroll for-besarya slowly
If you can not see shit like in the example photo above mean safe
Okay, from the images seem to me gross taxable sensor dust, use the default camera lens cleaning (look in your camera menu), or use the blower. If the dirt is stubborn, take it to a service center.
