If you own a digital camera, you have likely heard the word “pixel” used. Pixels are a myriad of dots that make up those beautiful photos you take, and the amount of pixels for your camera is referenced as “megapixels” (MP) which means “one million pixels.” For example, a 4.0 MP camera has four million megapixels. In the grand scheme of things, pixels in cameras can go bad. When they do, the affected pixels often show up as peculiar dots or spots on photos. Read on to discover how to identify three types of distorted pixels.
A hot pixel issue is an issue that may surface from time to time. It is somewhat a phenomenon because the spots may not appear on all of your photos. In fact, it is possible to have a hot pixel issue once and never have it occur again. They appear as bright spots and occur as a result of an electrical leakage during the photo taking process. Digital cameras are designed to “autofix” most hot pixel issues unbeknownst to the camera owner which is why they are not always seen.
If you have dead pixel issues, you may not have even noticed it unless several pixels are affected. This is because they appear as a black dot. The software installed in many cameras can detect dead pixels. When they are detected, the camera may attempt to mask the dead pixels.
Dead pixel issues that are noticeable can be corrected by sending the camera to the manufacturer if it is under warranty. You could also choose a local camera repair shop, like CameraTechs, if you cannot be without your camera for more than a couple of days.
The occurrence of stuck pixels are the most noticeable and difficult to remedy. If you have stuck pixels, expect to see signs of them in all of your photos. They appear as bright blue, white, green or red spots which can make the most beautiful photos distracting or a real “eyesore.”
Fixing stuck pixels is usually complex because the fix for the camera is highly dependent upon the manufacturer and model. For example, two digital cameras with stuck pixels made by the same manufacturer may require different steps to fix the pixels if they have different model numbers.
If your camera has remapping or auto-clean features, you can try running those first. If these programs are not available or you are not tech savvy, send the camera back to the manufacturer if it is within warranty. Otherwise, rely on a local camera repair shop.
