Shoot during “golden” hoursFrom sunrise until about 10 a.m. and from about 4 p.m. until sunset the sun is low in the sky and light with a golden glow. “Golden Hour” conditions create long shadows and a warmer color than at other times of day.


Shoot during “blue” hoursFrom just after sunset until about an hour later and from about an hour before sunrise until sunrise the sun sends its light out and gives the sky and world an indigo glow. “Blue Hour” conditions create rich colors and a cooler color feeling than at other times of day.

High-key lighting is a style of lighting for film, television, or photography that aims to reduce the lighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with high

contrast ratios, but now is used to suggest an upbeat mood. It is often used in sitcoms and comedies. High-key lighting is usually quite homogeneous and free from dark shadows. High-key lighting is usually quite homogeneous and free from dark shadows.

Low Key has a “Dark” feeling

Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting, three-point lighting uses a key light, a fill light, and a back light for illumination. Low-key lighting often uses only one key light, optionally controlled with a fill light or a simple reflector. Low key light accentuates the contours of an object by throwing areas into shade while a fill light or reflector may illuminate the shadow areas to control contrast.

Quality not QuantityThink of using flash to improve the quality of the light at a scene

rather than how much brighter the flash makes the scene


Sync Speed of Camera

In cameras with a focal plane shutter, the sync speed, or x-sync, is the highest shutter speed where the shutter fully opens when a picture is taken. At higher shutter speeds the shutter is only partially open, creating a slit that moves across the image sensor to make the exposure.

If you are using flash and your shutter speed is faster than the sync speed then only one part of your picture will be exposed to the flash.

In this camera setting the flash is used to help illuminate subjects in the foreground that would be too dark or have unflattering or distracting shadows. The flash “fills-in” the shadow areas with light to improve the overall look of the light on the subject.

• Apple Quad-LED True Tone flash with Slow Sync

• Four smart LEDs flash. The flash adjusts according to the color temperature of the environment, resulting in sharper, more brightly lit photos.

“Slow Synchro” Sometimes called

“Night-portrait Mode”In this camera setting using flash, the shutter speed is set to a slower setting (1/30 to 1 sec.) to allow some of the ambient light to be recorded. Slow synchro helps avoid the “taken in a cave” look of some flash pictures.


R E D E Y E• Flash too close to lens axis

• Pupils wide open

• Blue-eyed people are more prone to redeye

H O W T O F I X I T• If possible, hold flash

higher than camera lens

• Have people stare at a light before taking picture

• Use redeye tool in photo program to remove it

• Use redeye reduction setting on camera


First Curtain/Second Curtain Sync (also called Front Curtain and Rear Curtain)

http://notepad.yehyeh.net/Content/Photograph/ExposureGuide/high-speed-sync-flash.php

Camera shutters have two unique times when the flash can be triggered: 1.When it first is fully open and 2.When it is just about to close. If you are using a slow shutter speed and flash when photographing subjects in motion, the blur of the object with: First curtain sync will look to be in front of the moving object Second curtain synch will look to be in back of the moving object.
