Camera sensor cleaning
You say you love photography? Well, a sure way to kill your enthusiasm is to waste hour upon hour cloning out dust spots in photos. All because you haven’t cleaned your camera’s sensor in a while. Then when check your camera sensor with a sensor loupe, you’ll realize there are even more specks of dust than you thought! Therefore you need a thorough method of cleaning your camera’s sensor.
When you clean your camera’s sensor, you want to do better than just swirl crap around on your sensor with a swab. Here are the tools I use, and the method I use to clean my cameras’ sensors with a good measure of success and the minimum of frustration. Oh, for the pedantic photographers – I know we aren’t cleaning the sensor, but rather, the protective filter over it.
For those of you who can’t wait to hear how the story ends, here’s the plot twist – this device solved all my problems in removing dust specs. Where previously I felt like I was just moving crud around with the swab, this device – the Eyelid SCK-1 sensor gel stick (Amazon) – picked up every single spot that I could see with the magnifying loupe.
Cleaning your camera’s sensor
There’s a huge variety of tools and devices available on the market to clean your camera’s sensor. I’ve tried a few of them, but always come back to this thorough method, which I’ve adapted again.
- If your camera allows, you should first try and clean your sensor by activating the self-cleaning vibrating mode to dislodge dust particles.
- Now remove most of the existing dust on the sensor (and in the mirror chamber), with a dust blower.
- Use a swab with sensor cleaning liquid to remove stubborn particles,
or go to the next step immediately:
- Use a sensor gel stick to dab away any particles.
- Keep a sensor cleaning kit with me in my camera case for emergency fixes.
A puff of air to remove dust particles
If your camera allows, you should first try and clean your sensor by activating the self-cleaning vibrating mode to dislodge dust particles.
Even though you might have tried the vibrating sensor self-cleaning mode, it might still be necessary to add a few short, but soft blasts with a blower, such as the VisibleDust Zeeion Blower (B&H / Amazon). This will blow out most of the junk inside your camera. The manufacturer says this blower has anti-static capabilities – a good thing when you try to not attract more dust with unnecessary static.
Let’s take a closer look at our camera’s sensor
You may be able to see larger pieces of dust and lint with the naked eye, but the smaller the aperture you’re going to be shooting at, the more the smaller specks will be visible. So you need some way to have a magnified view of the dirt on your sensor. There are various options, but you will need something along this line – a sensor loupe.
Now we need to physically remove the obstinate dust particles
We have several methods of physically dislodging dust particles:
1. Use sensor swabs to (gently) sweep clean stubborn particles or smears, or
2. Use the sensor gel stick
Sensor swabs and cleaning fluid
Use sensor cleaning solution (B&H / Amazon), to very lightly moisten the swab with which you are going to clean your sensor. Just a drop of liquid on the swab and then with a wrist-flick get rid of any moisture droplets. You just want the swab to be barely wet.
There are several sizes of sensor swabs, depending on your camera’s sensor size, whether full-frame, 1.3x crop, or 1.5 / 1.6 crop sensor cameras.
It takes a bit of practice to use just the right amount of moisture, and the minimum of sweeps of the swab, to make sure you don’t leave drying marks. But this helps with obstinate particles.
Sensor gel stick
I’m pretty enthusiastic about this piece of sensor-cleaning gear – the sensor gel stick (Amazon). It really helped me get as spotless a sensor as I think is possible for us.
It sounds scary – you dab it directly onto the sensor to pick up specks of crud. But it works!
A carry-everywhere emergency kit
This is the kit that I keep in my camera bag when I am out on a shoot, just in case I notice some horrible dust particle when I play an image back. A quick-fix while on location.
Spending a bit of time before important shoots to clean our cameras’ sensor, is just good practice. It cuts down tremendously on post-production work. This is especially true if you shoot video!
I don’t necessarily go strictly through this routine every time, but these are the tools and methods I use to keep my cameras clean. It makes my life easier, even if I sweat a bit while cleaning the sensor.
Let’s hear from you what techniques you’ve been using with success.
