A single dead pixel means 0.0001% failure rate with 99.9999% of good pixels. Think of it this way – a typical 3 inch LCD from Nikon contains 920,000 pixels. So, what do you do with dead/stuck/hot pixels if you have them? If you only have one or two dead pixels on your LCD, don’t worry about them – dead pixels are a normal fact of life. If you decide to try it out, then do it at your own risk.

While you might find some online tutorials on how to map out stuck/hot pixels with various software (only works with very old DSLR models), I would not recommend trying those. Unfortunately in most cases, you cannot fix dead, stuck or hot pixels yourself.

You will probably see more hot pixels in the second photo at higher ISO than on the first one.

Analyze both images and see if you can spot colored pixels that look like very small crosses when zoomed in. Next, set your ISO to 800 and increase the shutter speed to something fast like 1/1000 while keeping the aperture the same. Set camera shutter speed to 5-10 seconds and aperture to a large value like f/16 (to decrease the amount of ambient light that could potentially enter the lens through small holes).

How to spot hot pixels: while keeping the lens cap on, set your camera to Manual mode, turn off Auto ISO and set your ISO to 100 (base ISO). My Nikon D3s had no visible hot pixels when it was new and now has plenty of hot pixels that are visible in longer exposure/high ISO images. Every single DSLR camera I have owned and/or used had hot pixels. Hot pixels will appear and disappear over time and if your brand new camera does not have stuck pixels, you can rest assured that you will have them at some point in the future. Hot pixels are very normal and they will show up even on brand new cameras, although manufacturers do their best to map hot pixels out during the QA process. Unlike stuck pixels, hot pixels only show up when the camera sensor gets hot during long exposures or when the ISO is cranked up above 400-800. It is normal for digital camera sensors and LCDs to have multiple stuck pixels. If you have a colored pixel (actually a small cross when viewed closely) that always shows up in the same spot, you have a stuck pixel. To find out if you have a stuck pixel on your camera sensor, take multiple different pictures at a base ISO such as ISO 100 or 200, then analyze the images at 100% on your computer screen.

If you notice a pixel that never moves and has the same color no matter where you point your camera to, you might have a stuck pixel on the LCD. How to spot stuck pixels: to see if you have stuck pixels, set your camera to Program/Auto or Aperture Priority Mode, then turn on Live View and point the camera around, while carefully looking at the camera LCD. Stuck pixels are very common, but not permanent like dead pixels – they might disappear over time. Unlike dead pixels, stuck pixels do not change their color from picture to picture. The colors can be red, green, blue or any combination of these colors. Stuck PixelsĬompared to dead pixels, stuck pixels always receive power, which results in a colored pixel that shows up in the same spot on the camera LCD or on the sensor/images. If you see a pixel that shows up in the same spot and changes colors every time, or appears darker than the surrounding pixels, it is most likely a dead pixel. Take several pictures with different colors and patterns, then analyze the image at 100% view size. Finding dead pixels on the camera sensor is tougher. Dead pixels will always show up in the same spot even if you move the camera. Simply turn on Live View and point your camera at a bright area such as the sky. How to spot dead pixels: dead pixels are easy to spot on the camera LCD. Dead pixels might appear on DSLR LCD screens and sensors over time, which is normal. Dead pixels are rare on digital camera LCDs and sensors – manufacturers typically take care of dead pixels during their extensive Quality Assurance (QA) process. A dead pixel is a malfunction that is more or less permanent and does not go away over time. Since digital camera sensors have color filter arrays, also known as “ Bayer filters” in front of them, dead pixels do not normally show up as a black spot, but will rather show up of different color than adjacent pixels, or will be slightly darker than adjacent pixels. A dead pixel is a permanently damaged pixel that does not receive any power, which often results in a black spot on the camera LCD.
