Usually all you actually need is the location of the two representations in space, but sometimes it is useful to know about other differences, and they can give you useful information for checking later, as well as a valuable experiential basis for working with others.
Try changing each of the submodality differences on your list one at a time in order to modify the loss experience and make it similar to the experience of presence. For instance, “Watch the still photograph, and allow it to unfold into a continuous movie of what happened before and/or after the still photograph. When the still has become a movie, notice to what extent that changes your feeling of loss into a feeling of fullness.” Change each submodality back before testing the next one. In the example given, you would make the movie of loss back into a slide before changing the black and white into color. Find out which submodalities are most powerful in reducing the kinesthetic feeling of loss and increasing the sense of presence. If you find that changing one submodality automatically changes some other submodalities on your list, that is an indication that it is one of the more powerful ones, what we call a “driver”).
