Video demonstration of high-speed flash photography. A flash is a device used in photography that produces a brief burst of light (lasting around 1 ⁄ 200 of a second) at a color temperature of about 5500 K [1] [citation needed] to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene.
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.
Tag Image File Format. A high fidelity computer file format for handling digital images that does not sacrifice colour and form detail in the way that 'lossy' compression formats such as GIF, JPEG and PNG do. [8] TLR: Twin-lens reflex. A camera with two lenses, one for taking pictures and one for viewing the scene.
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.
This also applies to Sony's SLT digital cameras, which use the image sensor for exposure metering all the time. As of 2012, no digital SLR or SLT camera on the market supported any form of real-time TTL flash metering using the image sensor. However, it can be expected that such methods will be introduced as image sensor technology progresses ...
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.

The rise of mirrorless cameras has changed digital photography. These cameras are popular for their modern tech, portability, and versatility. Unlike DSLRs, mirrorless cameras have electronic viewfinders or LCD screens for previewing photos and manual controls. They are smaller and lighter, but may have fewer lens options and shorter battery life.
