It can make memorising things easy and simple. It converts all information into images, like a camera taking a picture, "clicks" the brain and freezes it into an image, which is permanently retained in the mind, and can be taken as needed to reintegrate information.

People who learn to use the photographic memory function of the right brain can greatly improve their memory and quickly remember a large amount of information. The book which could not be remembered even after half a month, can be remembered after two or three times. The information you remember is deeply imprinted on your brain and stored permanently so that it comes back to you as clearly as a picture when you need it.

In technical terms, photographic memory is called eidetic. Psychologists prefer this term because tetanus differs from photographic images in many important ways. For example, the photograph does not omit any detail of the image, but the eidetic image is the most accurate depiction of only the most interesting and meaningful parts of the scene.

This super-sharp image memory is also different in several ways from the normal image memory that most of us experience. First, people with eidetic abilities reported that the images they remembered were as vivid as those of the original experience; Second, the eidetic seems to be "outside the mind" rather than in the mind. (Even if people with this ability feel as if they are outside the mind, they know that it is only an image in the mind.) Not only that, eidetic images can last for several minutes, in some cases, even days.

Photographic memory is more common in children, but less common in adults. By some estimates, only about 5% of children have eidetic capacity at most. Although no one knows why this ability is more common in children and less common in adults, it may be a developmental trait, just as people change their baby teeth as they grow older. The loss of this ability is likely to be related to the development of formal computational thinking in children. Formal operational thinking usually begins at the age of 11 to 12.

On the other hand, case studies have shown that the decline in photographic memory is associated with the development of language skills: people with this ability report that verbal description of an eidetic image recedes from memory, and they learn to control the eidetic image in this way, so that it does not interfere with normal thinking. A cross-cultural study in Nigeria further suggests that the loss of eidetic ability may be due to a conflict between language skills and visual imaging skills. This study, the researchers of life in the wave of tribal members are studied, and they found that the photographic memory not only widely exists in children, and generally exists in the adult, although members of the tribe to accurately draw earlier can see the detail of the image, however, those who move to cities, and learn to tribal members eidetic like ability is almost completely gone.

Whatever photographic memory may be, it is a rare ability, and if mastered and fully utilised, it will be of great help to our study, work and future development.
