The Mysteries Of Long Exposure

Expand Your Image Imagination

by Art Rosch

The human eye sees light in the moment. Film or sensors accumulate light through an entire exposure, as if it were a memory. Photons continue making impressions wherever they land on the sensor or film. Moving objects leave a distended, time-lapsei...

While you can choose enhanced color saturation when using your digital camera
via the Menu, this choice generally adds saturation to all colors at once. This
might work fine for some subjects, but there are many ways to "juice up"
selective colors later in the software. We'll work with two controls here,
Hue/Saturation and Selective Color, both used as Adjustment Layers.

Exposure Basics I

George Schaub

“Exposure” is shorthand for the delicate balance of the light sensitivity of the recording material (in our case the camera’s CCD or CMOS sensor with picture sites, known as pixels) with the amount of light in the scene. There are two parts of a camera system that control the amount of lightcomin...

Imagine yourself walking into a room where there are numerous objects covered with small mirrors. The mirrors follow the form and shape of the objects. The walls of the room have a slot that goes continuously around the entire room. Behind the slot is a light that shines into the room and that travels the entire distance, from wall to wall. As the light travels it passes through numerous color filters built into the slot. The light reflects off the mirror facets on the objects. You can also move throughout the room and observe the objects and the light by standing with the light coming in over your shoulder, from the side or even standing behind the objects as the light hits them.

High scene contrast always creates difficulties for photographers, whether
shooting film or digital. The difficulty stems from the difference between the
ways the film or sensor "sees" and how the human eye sees. Our eyes
are adaptive, and can resolve large variations in brightness by the way it scans
throughout the scene and the amazing reflex of automatically restricting and
dilating the pupil to adjust to bright and dark areas before us. While light
metering systems in cameras are impressive in the way they can read light, the
fact remains that at the moment of exposure the lens on a camera records a scene
at one fixed aperture, or opening. In most situations this is no problem, as
the meter averages light values and the bright and dark areas are distributed
through the recording medium properly. But high contrast presents a problem.

A
better solution is to use the --1 contrast setting. This
allows for smoother tonal gradations and addresses the need to
control the divergent light values in this backlit scene.
