Dead Pixel Test – Documentation
This tool allows you to check your camera for dead pixels. It also reports hot pixels which depending on
the length of the exposure and the threshold used in the test can be attributed to normal noise.

How it works
Make a lens cap shot. Close the lens with your lens cap, also make sure to close the viewfinder so no light
can get into the camera. Now make exposures with different shutter speeds ranging from 1/30, 1 second, 2
second and more.
Best results will be with TIFF files or other non-compressed or loss less compressed files as JPEG artifacts
will introduce more dead/hot pixels than you really have.
Run DeadPixelTest.EXE
Click the ‘Browse’ button and select one of the files to be tested. Then click the ‘Test’ button.
The image will be loaded and then the progress bar will show the progress of the analysis. After the test is
done the number of hot and dead pixels are reported and a histogram for the picture is shown. Also the dead
and hot pixels are shown in the list next to the histogram.
