The image is about 1 degree by 1.5 degrees in extent and the total exposure time was 25 minutes.

This process has 100nm resolutions and requires exposure time of 15-20 minutes.

The exposure time was two million seconds, or about 23 days.

The exposure time of the gun above the surface was around 75 seconds.

Start slowly and use short exposure times to build up a tan over time.

That ought to increase his exposure time by about half an hour.

They were taking a risk as it was and would want to trim their exposure time.

The images were primarily shot at night with very long exposure times.

The survey required photography with exposure times of up to 8 minutes.

Sky recordings are made every night with a long exposure time.

The lack of more than two shutter speeds was not a problem.

However, high shutter speeds reduce the exposure time and so are best used only in good light.

But not every situation offers enough light for photography at high shutter speeds.

Faster shutter speeds can be used to freeze the action.

Electronic control also made it simpler to time very long shutter speeds.

Slower shutter speeds are often selected to suggest movement in a still photograph of a moving subject.

Shutter speeds run from 1s to 1/1000s and B.

No mechanical shutter speed was provided, even in bulb mode.

One way he did this was to photograph moving subjects using long shutter speeds, so that their images would be blurred.

Short rotation cameras usually offer few shutter speeds and have poor focusing ability.
