Technical Stuff WHAT IS LONG EXPOSURE PHOTOGRAPHY ?

Using long speeds

Capture the fixed elements of an image sharply

Intentionally blurring, obscuring or streaking the moving elements.

The photographer to conveys the passage of time. WHAT IS CONSIDERED LONG EXPOSURE ?

No defined transition point A of 1/30 of a second or longer is required to record movement in a scene.

LE images vary from seconds, to many minutes, and even hours, depending on the subject and effect you are trying to achieve. WHY CREATE LONG EXPOSURE IMAGES?

A creative tool that is used to affect motion and how it’s conveyed in an image.

A moving subject when photographed with a fast shutter speed is captured frozen in time

The same subject photographed with a slow shutter speed becomes a blur. WHEN TO USE LONG EXPOSURE TECHNIQUES?

Low-light situations by default require slow shutter speeds and are easiest to achieve,

Can also capture long exposures in bright light by using Neutral Density (ND) Filters. TYPES OF LONG EXPOSURE IMAGES

Motion Blur: this can be achieved with any type of motion Water Vehicles Amusement rides Stars Clouds People

With motion blur images, the stationary Photo: Lynn Riding elements further emphasize the motion of the subject. TYPES OF LONG EXPOSURE IMAGES

Night Landscapes: Moon shots Starry nights Star trails Milky Way Aurora Borealis Photo: Roger Hill Covered by Roger Hill at our November Meeting; Not part of today’s presentation TYPES OF LONG EXPOSURE IMAGES

Urban Scenes: City Skylines Waterfronts Traffic Fireworks

Equipment: DLSR or mirrorless camera, with Bulb mode capability Lens, appropriate for the scene Tripod Remote cable or wireless release Extra battery (LE uses lots of power) Neutral Density (ND) Filter, Variable ND or Polarizer TECHNICAL STUFF

Camera Settings: Shoot Raw; More data for post processing Shoot using Manual Exposure Mode When shooting in low light and at night, turn down your cameras monitor brightness Turn off lens Image Stabilizer (IM, VR, etc.) Turn on Long Exposure Noise Reduction. Doubles time needed for exposure TECHNICAL STUFF

What is Exposure? Shutter speed ISO TECHNICAL STUFF Exposure Settings: Many combinations will provide the desired exposure. Shutter speed used to affect image Set for long duration Adjust ISO and Aperture to get a correct exposure for the scene Use low ISO Use small aperture TECHNICAL STUFF Exposure Settings: Low light situations require slow shutter speeds TECHNICAL STUFF

Shooting in the Dark : Scout out the area in daylight. Bring a flashlight Auto focus does not work in the dark TECHNICAL STUFF

How do you get Long Exposure Times in Daylight ? Use of lens filters will increase exposure times: Polarizing filter (most basic, with f-stop reduction 1.5-2 stops) Neutral Density (ND) Filters (f-stop reduction of 1 to 10 stops) TECHNICAL STUFF

What is a ND Filter? A grey filter that reduces the intensity of light entering the lens Can be either screw on style or slide in types that use a holder attached to the end of a lens. Available in different densities that cut the light transmission by a certain number of stops. Circular screw on filters can be stacked to get their cumulative effect. Variable ND Filter, which are made up of two sheets of polarizing material. As one is rotated the density of the filter varies, allowing you to dial into the desired number or stops required.

How to Use an ND Filter: Stabilize camera Compose shot Set exposure for the scene Focus on subject Turn off auto focus Secure focus barrel of lens with gaffer tape
