How To Test Digital Cameras

Testing a camera can be a formidable task, especially when we know how much effort the company has put in to build it. However, it’s always a good practice to test one before you actually pay for it. Given below are some simple tests which one should carry out for testing a digital camera.

  • Noise Test – Every digitally captured image has some sort of noise. However, its degree varies across different cameras. Camera that has high ISO settings tends to have more noise. Larger physical size of the sensor also leads to more noise. The amount of noise can be evaluated by capturing the images of an X-Rite Munsell ColorChecker Chart target.
  • Color Reproduction Ability Test – While colors can always be corrected with the help of software, but it’s generally best to buy a camera that can provide as much accurate color reproduction as possible. For this test, we can capture the image of the above mentioned target and then analyse the image according to industry standard sRGB color space.
  • Sharpness Test – An image’s sharpness has a direct relation with the resolution of the camera. To test the sharpness, we capture an image of ISO 12233 test target and then the images are analysed using Imatest image-analysis software for evaluating the sharpness of the image produced.
  • Time-to-First-Shot Test – This test is designed to measure the speed of the camera as how soon a certain camera is able to capture its first image. For this, after powering-up the camera, we first tend to determine the fastest method of taking a photo and then we shoot as soon as it’s ready.
  • Shutter-Lag Tests – These tests measure how efficiently and quickly a camera is able to capture an image once we press the shutter-release button. For this, we commonly use shutter-lag tests created by any renowned digital company and then analyse the result obtained.
