Flash modes allow the user to choose between common settings such as: Fill flash, to always use flash; Auto flash, which will use flash in low-lit areas; Red-eye reduction, which may flash once before the actual photo in order to shrink the subject's pupils and reduce red-eye; or, Flash off, which will never use flash.
Using an umbrella or softbox (the flash will have to be off-camera for this) makes softer shadows. A typical problem with cameras using built-in flash units is the low intensity of the flash; the level of light produced will often not suffice for good pictures at distances of over 3 metres (10 ft) or so. Dark, murky pictures with excessive ...
The effect is produced by adding a small and even level of exposure to the entire image. Since exposure levels increase logarithmically, this tiny level of additional exposure has no practical effect on an image's mid-tones or highlights, while it shifts the darker areas of the image into the practical sensitivity range, thus allowing the darker areas of the image to show visual detail rather ...
Straight out of camera. Images as shot out of camera; implied is no post processing, slang STU: Shoot through umbrella. White translucent photographic umbrella; a flash is shot inside the umbrella and the light is diffused onto the intended target; provides a soft, large light source. Sv: Sensitivity value.
Nikon refers to this technique as "3D matrix metering", although different camera manufacturers use different terms for this technique. Canon incorporated this technique in E-TTL II. More advanced TTL flash techniques include off-camera flash lighting, where one or more flash units are located at different locations around the subject.
Either the flash is firing too late or the shutter speed is too fast (shutter moving vertically). Note the different exposure levels. In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.

Guide number distances are always measured from the flash device to the subject; if the flash device is detached from the camera, the position of the camera is irrelevant. Furthermore, unless a flash device has an automatic zoom feature that follows the setting of a camera's zoom lens, guide numbers do not vary with the focal length of lenses.
