Dust is a problem with all digital singlelens reflex cameras. It can enter the camera whenever you change the lens. This dust often finds its way to the glass filter that covers the digital sensor. The sensor is made up of millions of lightsensitive elements, each around 6 to 8μm square. It does not need a very large piece of dust or dirt to ...

· Squeeze vigorously to dislodge dust, and do this several times, amount varying based on the vigor of the squeezes and the amount of dust you found on the sensor. Put a lens back on the camera, and shoot the sky again to see if you got all the dust. If you didn’t, repeat the operation, noting carefully where the dust is located, and try again.

· Check out the full video up top to see how it works and how Morganti uses it to remove sensor dust. And if you appreciate this tip, drop your own “deceptively simple” postprocessing trick in ...

This is dust that you get on the camera’s sensor and which shows up in your images as dark marks or flaws on your photos. Most often you’ll see this in the sky but it can appear anywhere in an image and it will appear in the same place in all your images – …

· At F11 F22 there''s up to 8 spots. Show activity on this post. If the lens is producing same bad image or doesn''t function properly on different bodies, then the lens is damaged. If the body is producing same bad image with different lenses, then the sensor/otherbodypart is damaged. Show activity on this post.

· Dust on the sensor becomes much more visible when you work with small apertures (high f numbers). Put your camera in Av mode, choose the smallest aperture f22 or higher, take a picture of the sky. You''ll notice it immediatly. My personal experience is as follows: Sensor dust removal on my K10D works somewhat, I have it on when powering up the ...

· I have had dust on all my other brand open sensor cameras and duly removed it. So I do know what dust on the sensor is and am quite irritated by it. As a user of closed body Ricoh cameras I am very interested in keeping dust off my sensor. So I need to know how to look after my camera so that it does not happen to me.

Adding a cleaning solution to the Visible Dust Sensor Cleaning Swabs is what is recommended, but I find it very hard to get all of the lint off of the sensor when using the wet method. If there is serious dirt on the sensor, I definitely use the wet method which involves adding a very small amount of the proper cleaning solution to the tip of the sensor swab and proceeding as with …

· How to Remove Dust in Post (Method 2) The next trick works pretty well, and depending on your footage, you can improve the picture quality anywhere from 70 – 90 percent. Here’s how it works. 1. Duplicate your shot, and layer the double above the original. 2. On the duplicated video, create a circular mask that fits the same size as the dust ...

· That is dust on the sensor (well the IR filter over your sensor), dust specks in the lens are not capable of causing spots on the image like this. The reason you can see them at a small aperture and not at a large one is that the light rays are far more linearly aligned at f22, hence they cast a shadow remember the surface of the filter where they sit is not ON the …

Those out of focus black dots in the background of your photos are dust spots. They’re artefacts on your camera’s sensor, or less commonly on the lens, which are picked up in the photo itself. They’re seriously irritating, and even when you think you’ve got rid of them all during editing, you could well find more later.

· To do this, I set a long shutter speed of, say, five or more seconds, and a small aperture of ƒ/16 or ƒ/22. The small aperture makes any dust particles appear more well defined on the sensor (which is also good to know if you get dust on your sensor during a shoot and want to minimize its appearance; if that happens, just open up the aperture).

· Camera sensors are dust magnets and notoriously prone to dust buildup if you’re not careful, so you will inevitably have to clean your camera’s sensor every so often, or once you start to discern those annoying spots on your photos.

We all know that dust on a DSLR sensor can range anywhere from the mildly annoying to downright problematic. You can try avoiding it, but the simple, …

· One of the most frequently asked questions that I get from our readers, is what to do with dust inside a lens and whether it is something to worry about. I decided to write an article on this subject, because lens dust and flecks are a very common issue not only for camera sensors, but also for lenses.

· If your sensor is that dirty your camera should be sent in to Canon for cleaning. As for if it is the lens or the sensor, well, I would try different lenses or taking a picture without any lens on. If you still see scratches, then it is a problem with your sensor, in which case you need to send your camera into the manufacturer.

· If you’re really, really stuck with dust on your sensor and no chance in the short term to clean it, you can try using a larger aperture (eg. f/4 or f/). That might help minimize the problem on the image. Smaller apertures (eg. f/22 or f/11) tend to be more prone because they have a much greater depth of field.

· Now I just use a dry sensor swab, without using the sensor loupe, just to get those stuborn objects that the "auto cleaning" feature in the camera, my Rocket, or sensor brush won''t remove. I change lenses a lot and no matter how careful I am, crap finds its way to the sensor (actually the AA filter on non modified cameras).

· How to see sensor dust. If your camera has dust on its sensor, you can quickly spot it by doing the following: Set your camera on Aperture Priority …

Answer (1 of 3): You should be able to see the scratch on the lens by looking at the lens glass from an angle (not through the camera but directly at the front of the lens) in much the same way that you can see a scratch on a window. A scratch can …

· Dust on the sensor: with a thick sensor stack (Olympus, Panasonic), the flecks are less sharp than with spots on the sensor of a Nikon/Canon SLR …

· Open it in Photoshop, increase the contrast, zoom in, and check for spots. They’ll look like in the photo above. Remember that because of DSLR technology, the image is flipped 180 degrees vertically, so you have to figure out where the dust spots will be on the sensor. However, there’s another option.

· When you turn it on, you can hear a flip sound and see the sensor exposed. Use one hand to point the camera vertical or downward to avoid getting more dust on the sensor and use the other hand to hold the air blower and gently puff a few air bursts. 3. Wet Cleaning.

· But, if you are going to do the cleaning yourself, before cleaning the camera’s sensor, you need to make sure that it is definitely sensor dust because you do not want to end up cleaning an already clean sensor. If there is sensor dust, it is clearly going to show up in your images. That way you know that the sensor needs cleaning.
