How do I know if my camera sensor needs cleaning?
Have you noticed strange spots or dark specks appearing consistently in the same place on your photos? Camera sensor dust spots can cause these blemishes.
To check for sensor dust, you can do an easy test: Simply shoot a photo of a plain white wall with your camera on manual mode and the aperture set to f/22 or smaller. If you see dark spots, your sensor may need cleaning. For a more thorough inspection, load up your images on a computer screen and zoom in on the image; any dust particles will be more visible.
Why should I worry about cleaning my camera sensor?
Whether you have invested in a high-quality full-frame mirrorless camera or a beginner-friendly DSLR, you want it to perform at its peak. The benefits of a clean camera sensor include sharper, clearer photos with fewer artefacts. While sensor spots and dust can be corrected in editing software like Photoshop Not sure which editing tool is right for you? Check out our comparison of Adobe Photoshop vs Lightroom., this is time-consuming and can slow down your photography workflow; it can also become tricky in images with intricate details. To ensure your photos are pristine from the start, it's best to address sensor cleanliness proactively.
Camera sensor cleaning at home vs camera service
If you have very minimal dust on your camera sensor, it is worth trying some simple fixes. This includes the in-camera sensor cleaning feature that many modern digital cameras offer Keeping your camera firmware up to date also ensures this built-in cleaning feature performs at its best., or using a simple blower brush. These methods can be effective for removing larger particles, but more stubborn dust or debris may require more specialised attention. Camera sensor cleaning kits are available, but as the sensor is the heart of your camera, it's often advisable to leave in-depth cleaning to the professionals Alongside professional servicing, it's also worth considering camera insurance to protect your investment from unexpected damage..

How to Clean a Camera Sensor Safely
Knowing how to clean a camera sensor correctly can save you from costly mistakes. Start with the least invasive method: use your camera's built-in sensor cleaning function, which vibrates the sensor to dislodge loose dust. If spots persist, use a rocket blower — never compressed air — to gently remove debris without touching the sensor surface. For stubborn contamination, sensor swabs with the correct cleaning solution (matched to your sensor size) can be used in a single, smooth stroke. Always work in a clean, low-wind environment and ensure your battery is fully charged before opening the mirror box or shutter. If you're unsure at any stage, stop — improper technique can cause permanent damage. Ted's Cameras offers professional sensor cleaning services Australia-wide for peace of mind.
Understanding Camera Sensor Dust: Causes & Prevention
Camera sensor dust is one of the most common issues photographers face, particularly those who frequently swap lenses. Every time you change a lens, you briefly expose the sensor chamber to airborne particles. Dust settles on the low-pass or anti-aliasing filter sitting in front of the sensor, showing up as dark, soft-edged blobs — especially visible at narrow apertures like f/16–f/22. Mirrorless cameras can be more susceptible because the sensor is directly exposed when the lens is removed. To minimise dust ingress, always change lenses in sheltered environments, point the camera body downward when swapping, and fit a body cap immediately. Investing in a weather-sealed camera body and lenses also significantly reduces dust contamination over time.
Dead Pixels vs Dust: Know the Difference (+ CCD Sensor Cleaning)
Not every blemish on your image is dust — it could be dead pixels. Unlike dust spots, which appear as soft grey or dark blobs that shift when you change aperture, dead pixels are sharp, fixed bright or black dots that appear regardless of aperture or lens used. Dead pixels are a hardware defect requiring sensor repair or replacement, not cleaning. If you're shooting with an older CCD sensor camera, CCD cleaning follows the same principles as CMOS sensor cleaning — rocket blower first, then wet swab if needed — but CCD sensors can be more delicate, so extra care is warranted. Unsure whether you're dealing with dust or dead pixels? Perform the white-wall test at multiple apertures: if the spot disappears at wider apertures, it's dust. If it stays sharp and fixed, book a camera service with Ted's Cameras for professional diagnosis.
