If 
you want to understand a little more about how to develop the photographic memory function of the right brain, below is an interesting excerpt from a Right Brain Kids’ newsletter explaining how it works.
PhotoEyeplay – one of the Wink activities from Right Brain Kids – helps train your photographic memory. Having a photographic memory is the key to speed reading and speed learning.
After-imaging exercises works with the negative images created by the eye. For example:
1. Gaze at the color red. When you look at red for a long period of time, you continually exercise the red cones within the eye.
2. Look at a white board, sheet of paper, or wall. When you look away, and refocus on a clear, white surface,
your red cones rest. They turn off.3. The negative image comes alive. The color white contains all the colors in the spectrum, you normally use all the cones within the eye to discern it.
So while the red cones are resting, the cones responsible for reproducing blue and yellow do all the work. Together, they create an after-image… green!
It takes time to develop a vivid photographic memory through after-imaging. How long it takes varies from weeks to months to years. It is usually easier for children to develop compared to adults.
The initial intention is to create an after image. The after image will appear as a negative image of the original image. For example, red will appear as green, blue will appear as yellow, etc. The image you will see is similar to the film negatives from the old-style film cameras.
Over time, with practice, you will eventually be able to see the original image in its true colours.
The following is an account from a mother describing her child’s first photographic memory experience for some inspiration:
“Mommy! Mommy!”
I heard an excited child cry from the den.
My mother’s instinct told me that the cry was one of excitement, but it certainly made me run to confirm it!
Nine-year-old Justin was already walking toward me with a face full of pride and surprise!
“I did it!” he cried.
“Did what?” I queried, hands on his shoulders to stop his excited body from moving in gleeful gyrations.
“I saw a positive image — not an after-image; the REAL picture!” he explained.
“I was watching TV and during the commercials, I saw an ad with a red coffee can at the end. I heard a sound outside and turned to look out the window. When I turned, the picture I was watching stayed in view. I could see both the red coffee can AND the window!”
Justin had been after-imaging since he was five years old. The idea of seeing the original image seemed like a faraway dream. But now, he had experienced his first “flash” of photographic memory — a relatively long flash, at least for the first time — and he was ecstatic!
