You can see a sharp change of something like 3% in light intensity, but less than that gets difficult.

For five or six minutes there was a slow reduction in light intensity.

The body colour can be quite variable, depending on light intensity.

The light intensity is different above and below water.

The most basic eye change is connected with variations in light intensity.

There are few coloured oil drops, which would reduce the light intensity.

The hue of the leaves varies according to light intensity.

It can only operate in a fairly narrow range of light intensity.

Of course, measuring light intensity only gives us a black-and-white image.

In longer, angled, or flexible tubes, part of the light intensity is lost.

The bhangmeter starts eventually to record an increase in visible light intensity.

The light intensity rises to full magnitude in about 0.1 microsecond.

The lower the f-number, the higher light intensity at the focal plane.
