Step-by-Step Guide to Cleaning Your Camera Sensor

ขั้นตอน 1: Prepare Your Workspace

Choose a clean, dust-free environment to minimize the risk of introducing new debris. A well-lit area or a desk with a clean surface is ideal. Turn off your camera to avoid static electricity, which can attract dust.

ขั้นตอน 2: Inspect the Sensor

Set your camera to manual cleaning mode (check your camera’s manual for instructions). This locks the mirror up and exposes the sensor. Use a magnifying loupe or sensor scope to inspect the sensor for dust, spots, หรือรอยเปื้อน.

ขั้นตอน 3: Remove Loose Dust with a Rocket Blower

Hold your camera facing downward and use a rocket blower to gently remove loose dust particles. Avoid touching the sensor with the blower, and never use compressed air, as it can damage the sensor.

ขั้นตอน 4: Use Sensor Cleaning Swabs

If dust persists, it’s time to use a sensor cleaning swab. Apply a few drops of sensor cleaning solution to the swab (do not oversaturate). Gently swipe the swab across the sensor in one direction, then flip it and swipe in the opposite direction. Avoid pressing too hard or going over the same area multiple times.

ขั้นตอน 5: Inspect Again

หลังจากทำความสะอาดแล้ว, inspect the sensor again using your magnifying loupe or sensor scope. If spots remain, repeat the process with a fresh swab.

ขั้นตอน 6: Reassemble and Test

Exit manual cleaning mode and reattach your lens. Take a test shot of a plain, evenly lit surface (like a white wall or sky) at a narrow aperture (f/16 or higher). Review the image for any remaining spots.
