How to Clean Your Camera Sensor -
Dust spots are a real problem when it comes to dslr cameras. The constant changing of lenses allows dust to sneak onto the sensor when you're not paying attention. And even if you are paying attention, dust can still find a way to accumulate on your sensor. This means you have to clean the camera sensor, which is something that is dreaded by both professional and amateur photographers alike.
Check for Dust Spots -
To check for dust spots use a small aperture like F22. You can either shoot it against a blue sky, or use a white background. To ensure that you are seeing dust spots on the actual sensor, you should gently move your camera around when you're taking the picture. This helps to blur everything except the dust on the sensor. If you see a lot of tiny grayish dots or blobs, then you need to clean your camera sensor. If the dust spots only show up when your camera is still, then you may just need to clean your lens or filters.
The Rocket Blower Technique -
When used correctly, the rocket blower technique is one of the safest ways to clean your camera sensor. And be careful when you use an air blower because some of these devices may spray gunk onto your sensor. The rocket blower will not spray anything on your sensor, so it is your best bet. In order to use the rocket blower technique, you should first shut off your camera.
This ensures that no static electricity attracts even more dust to your camera sensor. After this, remove your lens. Then place your camera on a tripod, and face the camera so the sensor is pointed downwards. This allows gravity to pull the dust away from your sensor after you've used your rocket blower.
Then you'll need to turn your camera back on and open up the mirror, which will expose the sensor. Your camera manual will tell you how. After the sensor is exposed, use bursts of air from your rocket
blower to remove any dust that's on the sensor. Around three to five seconds of consistent strong bursts of air should suffice.
Be careful not to shove your rocket blower's tip past the lens mount; you don't want to bash it into the sensor or some other sensitive part. And never use compressed air; the chemicals in it could damage your sensor. Also remember that the rocket blower will not remove some types of dust. Some dust requires a more unique approach.
The Wet Technique -
The wet technique is more dangerous than the rocket blower method. The reason for this is because you're making actual contact with your camera sensor. And since you're actually touching the sensor, you're more likely to scratch it. However, many people use this method and have no problems with it. There are several types of kits for you to choose from, but one of the more recommended kits is made by Eclipse. It usually will consist of sensor swabs, pads, a wiping cloth, and some fluid.
Again, to use the wet technique, you'll need to turn off your camera. Mount it on a tripod to keep the camera steady, and make sure you're in as dust free of an environment as possible (like a bathroom). Then remove any lenses on the camera, and expose your sensor. There's no need to point the camera downwards this time because you'll need to see the camera sensor.
After this, take one of your sensor swabs and apply some Eclipse fluid to it. Then gently wipe it across your camera sensor on one side, and then turn your sensor swab over. Go back in the opposite direction with your sensor swab, and you're done. Keep in mind that it may take multiple cleanings for this to work.
Use a Brush -
To clean your camera sensor with a brush, you'll again need to follow those same steps that were utilized in the wet technique. Place your camera on a tripod, turn it off, remove your lens, expose the camera sensor, and begin the cleaning. Simply wipe the brush gently across your sensor, and when you're satisfied stop. You should be able to see if you were successful or not.
But what type of brush should you choose? Some people will go the cheap route, and buy an inexpensive brush. And others will spend a lot of money. Either one may work. Whatever you decide on, just make sure that the brush has been specially designed for a dslr camera sensor. If it isn't, you might have to send your camera in for repairs. Damages could cost you a few hundred dollars or more.
Use a Professional -
Sometimes the above techniques will still not remove the dust, or perhaps you just don't want to do it yourself. After all, most dslrs are rather expensive devices that nobody wants to damage. When a
professional cleans your camera, you will usually pay a hefty price for the cleaning. However, sometimes people find places that will clean your camera for free. But you can usually expect to pay between twenty-five and one hundred dollars. And usually, the professional does a good job. Unfortunately, sometimes this is not always the case. So be sure and check your camera for dust spots when you reacquire it.
Cleaning your camera sensor is a delicate process that terrifies many photographers. However, if you take the proper precautions then you will likely be just fine. But remember, there's always a slight risk when you do this. ©JR All Rights Reserved
