    Default Sensor Cleaning.

    I'm not that fastidious with sensor cleaning. Nearly all of my images are one stop down from wide open and quite often wide open, so I never get down to F16 or smaller, where any dust bunnies will show up on the final image. Then, I shoot a landscape and want lots of depth of field and go for F16 and find I have an image full of dust bunnies. Even worse, I missed out on a free sensor clean at a Canon Pro day, just a week before.

    I have all the gear for this including a 10x loupe with led lights, but it just doesn't focus on full frame sensors - ok with 1.6 and 1.3 crop sensors, so I have to do it the long way:


    • Take an out of focus shot of a well lit white subject - paper or card, or a white wall, @ F16, or F22.
    • Upload to computer, adjust contrast to provide just whites and blacks to show the extent of sensor dust.
    • Open the sensor and use a hand blower, sensor brush, or Arctic Butterfly brush to remove dust.
    • Take another shot, upload, adjust contrast and examine results.
    • A lot of my remaining spots were circular and most likely oil spots, so required a wet clean.
    • I use Sensor Swab with Eclipse E2 fluid for a wet clean.


    Altogether, I had eight attempts to clean the sensor to my satisfaction and including the start and finish shots, that was nine photo's and uploads.

    I should now be ready to shoot a few landscapes in a week or so's time, when I am in Bridlington, Bempton and the Farne Islands.

    It maybe cleaned Colin, but it’s not clear in my mind what the heck you have done. Way beyond my knowledge.

    Using a setting on the camera, it opens the shutter so that you can remove any dust, or oil spots that have settled on the sensor. I had to learn old school, but there are plenty of videos on uTube etc. these days to show how and why. Hope that helps.
