Hi it's me again

Hope u're all having a wonderful weekend!!
I came across a website detailing the technique aallen posted: www.photomind.com U can e-mail them for a more detailed version of the 'lessons' on the site.
<--I'm not affiliated with them in any way, so I don't know what their privacy policy is like (eg if u e-mail their autoresponder for the 'lessons' I don't know they might do with ur e-mail address).
I also found another technique in a book called Superlearning. The book was 1st published in 1979, so it's probably v. outdated. But there's no reason why the technique shouldn't work.
Here it is: (copied straight from the book, hope the authors don't mind!
)
I AM A CAMERA
There are visualization exercises for improved concentration and memory. Get comfortable and use your favourite method to reach a relaxed state.
-Introduction to mental screen:
Imagine your head is a camera. Imagine your eyes are the lens of the camera. You're going to take some mental pictures. Concentrate on several objects within the room
A lamp
A chair
A book
A rug
A plant
Next center your attention on an open space on the wall. Pretend your head is a projector. Those pictures are now in your head. Project them onto the wall. This is done with eyes open.
-Suggestion:
Each object should be done separately at first to absorb more detail. Then do the exercise with 2 objects and gradually add others. Work up to bringing in a whole tray loaded with objects and take quick mental snapshot of it. Project it on the wall to try to recall all the objects in detail.
Now shut your eyes and imagine a large, white screen in front of you. This is a mental screen.
Open your eyes and look at several objects again. Close your eyes and project the images of the objects on the mental screen. Start with 1 object, and increase the number of objects.
Experiment with this technique on your own. Take a picture of a friend - in your home, or in your friend's home. You can take pictures this way any time - you can practise while standing in lines or waiting in traffic. It will enhance both memory and concentration.
Hope this info is useful to someone out there. Any comments/feedback v. welcome - perhaps someone's come across a newer/better version of this exercise?
