Using Flash In Photography

A flash is a device used in photography that produces a flash of artifical light to help illuminate a scene. When using flash there are many advantages and drawbacks.

Flash units are commonly built into a camera but many cameras allow separate flash units to be mounted via a standardized mount bracket.  In professional studio photography, flashes often take the form of large standalone units or studio strobes that are powered by battery packs or connected to mains.

The advantages of flash photography are very basic. 

• Artificial light can be produced if the area of work is too dark.
• Flash can add impact and expose the image correctly.
• Flash can highlight an image and pick up important details.
• With external flash, you can change the direction where the light is coming from.

The drawbacks of flash photography are also very simple.

• One of the typical problems of built in flash is that it is often low intensity.
• “Red eye” occurs because when a light is shined on the human retina, it reflects straight back where it came from. This occurs when flash is used, but can easily be removed using programs such as photoshop.
• Flash simply distracts a subject from their photographer, therefore reducing the number of pictures that can be taken without irritating the subject.
• Flash can create shadow outlines which ruin pictures and are hard to remove.
