  • ISO Sensitivity | Learn How ISO Sensitivity Works

    ISO Sensitivity. ISO is actually an acronym, which stands for International Standards Organization, and the ISO rating along with the shutter speed and aperture setting are the three elements that determine the final exposure of the photographic image. ISO Sensitivity and Image Noise. With film stocks, the lower ISO rating also meant that the photosensitive grains of salt on the film acetate were very fine, thus producing a smoother, cleaner image. ISO Speed vs. Motion Blur. Lower ISO ratings produce color-accurate, smooth and aesthetically appealing images… and this requires ideal lighting conditions. ISO Speed and Image Sensor Size. The size of the digital camera’s image sensor dictates what ISO setting provides the least amount of digital noise. One must understand that image sensor size is not the same thing as pixel count.

  • Why are My SO2 Sensors Failing Early?

    Nov 30, 2017 · This reduces the sensor sensitivity significantly and can cause the sensor to fail calibration. Why do SO2 Sensors Recover? While the electrolyte in SO2 sensors can easily lose its water under low humidity conditions, it can also absorb moisture from the air. This increases the ion mobility and causes the sensor sensitivity to recover.
