Note that the polarizers can increase the efficiency by reducing scattered light, however in a modern setup with a sensitive digital camera, they're not required.

Some is lost as heat - again tiny but measurable with infra-red sensitive cameras and slow motion.

Dr. Mihalcescu, a physicist by training, used a highly sensitive digital camera.

She also drew the protective covers over sensitive external cameras and sensors.

In events where more light is produced, less sensitive cameras or even the naked eye can be used to visualize the image.

It is therefore considered as the most sensitive camera in the world.

Not all these conditions come as revelations, but everywhere a sensitive camera captures the loneliness of defenseless children.

The sensitive cameras at the center caught the movement when Gettysburg left the station's dock.

The plants glow faintly for an hour when touched, but a sensitive camera is needed to see the glow.

But very sensitive cameras on occasion have captured its eerie glow.
