Why does the sensor get dirty? Recognising when the sensor is contaminated. The basic internal parts of a Digital Single Lens Reflex Camera The best strategy to ensure a safe and successful sensor clean. The different sensor cleaning methods available today. When to clean the sensor Cleaning the Mirror and Focussing Screen Hygiene After reading through this material you should have a good knowledge of the inside of your DSLR, know when the sensor is contaminated and how to safely clean it using a method of your choice. The guide is quite long, as the intention is to educate as well as to inform. If you wish to skip any section, please use the chapter links above to move quickly around the article. Why does the sensor get dirty? Ten years ago, when most images were shot on film, dust was not much of a problem for photographers. Since a fresh piece of film was used for each exposure, any dust present on the film only affected that single exposure. Of course dust was a big problem for the photo laboratories that developed and printed film. A good lab would go to extraordinary lengths to prevent dust spots spoiling your prints. With today’s digital cameras, every exposure is made on the same imaging sensor. Hence a spot of dust on that sensor will appear on every image. Because most compact digital cameras have a fixed lens and a well-made case, dust does not often find its way inside the camera and onto the imaging sensor. Although its not unusual for an older compact camera to suffer from the odd spot or two of dust. However a digital single lens reflex camera has a removable lens.

Canon DSLR Error 99 Fix To isolate the cause of the issue, do the following: 1. Turn off the camera. 2. Remove the lens, battery, and CF card. 3. Allow the camera to sit without power for approximately 20 minutes. 4. Insert a fully charged battery, and turn on the camera. 5. Depress the shutter button as you would to take a picture. Does the “ERR 99″ message appear? If it does, then the camera should be serviced. If it does not, then please proceed to the next set of steps: 1. Turn off the camera. 2. Insert the CF card. 3. Turn on the camera. 4. Format the CF card in the camera. 5. Depress the shutter button as you would to take a picture. Does the “ERR 99″ message appear? If so, then the CF card is the most likely source of the issue. Try using a different card. If the message does not appear, please complete the following steps: 1. Turn off the camera. 2. Clean the lens contacts by gently rubbing them with a pencil eraser or soft cloth. Be careful that you do not let any debris fall into the camera body. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them. You can use a regular old pencil with a red rubber eraser. Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly inside the camera. 3. Reattach your lens. 4. Turn on the camera. 5. Depress the shutter button as you would to take a picture. If the “ERR 99″ message only appears when one particular lens is attached, then that lens should be examined by a service technician. If you see the “ERR 99″ with a different Canon lens attached, then the camera should be serviced.
Camera Recommendation for Dental Photography January 2014 124 Edward Street, Room 346 Toronto, ON, Canada M5G 1G6 Tel: 416-979 4900 ext. 4414 Bauer Seminars: 905-264 9524 firstname.lastname@example.org Introduction The digital camera is a necessary tool in every dental practice. The type of digital camera system necessary will depend on the work being done and the output being produced. A Digital Single Lens Reflex, or DSLR, camera system is required for high quality close-up macro photography. A Ring Flash or Ring and Point Flash combination mounted on the front of the lens is required for any intra-oral photography. The lens required is dependent on the views necessary: • • • 90mm, 100mm or 105mm macro lens extreme close-up, up to 2 teeth 85mm macro lens up to a quadrant 60mm macro lens no smaller than a full mouth While all these lenses allow you to focus on very small areas, it also means that the working distance between the lens and the subject is very short. This means that there will be a Using lenses with a shorter focal length, can result in the lens and the flash touching the cheek of the patient, if you try to get an extreme close up view. Restorative Dentists, Cosmetic Dentists, Prosthodontists and Periodontists, need this type of camera system, because of the extreme close up views, colour accuracy and deﬁnition that must be documented for this type of dentistry. Orthodontists can use a 60mm macro lens, because they typically document a full mouth. Mirrorless SLR systems: These cameras are currently only useful for hobby photography. While the small size of the cameras is very appealing, and close up views can be obtained with some of the lenses, the problem comes when lighting the objects. I have not found a flash for these cameras that will allow for a well-lit intra oral photograph without shadows. Hopefully this will change in the future. All cameras require a very speciﬁc set-up for clinical dentistry photography. Exposure set up and ﬂash calibration will only be provided through photography courses or through purchases from Dental Photography suppliers.

An internal mirror reflects the view directly from the photographic lens into the viewfinder. When the button is pressed to take a photo, this mirror is instantly pulled upward (this is the “clicking” or “tapping” noise you hear) and out of the way of the shutter, which slides open to expose the imaging sensor (the digital “film”). Because you see directly through the photographic lens, there is no need for a second “viewing” lens (as with older camera designs), thus – single lens reflex. • The SLR design is superior to other designs because it allows the photographer to see through the viewfinder exactly what is seen through the lens and what will be “seen” by the imaging sensor. When looking through the viewfinder of non -SLR cameras, the image seen is not exactly the same that the imaging sensor or film “sees”. • Point-n-shoot digital cameras have electronic LCD viewing screens at the rear of the camera that show a digital representation of the view through the lens. But an SLR is still the only camera style that allows a real-time optical view through the photographic lens. This inherently allows for faster and more precise operation of an SLR camera over other types. About user manuals and this guide DSLRs (and for that matter all digital cameras) are capable of many different options and uses. Learning to use a digital camera is in some ways like learning to use a computer or cell phone or any other electronic device.
