Submodalities are a classification of variables within a “modality”. Technically, NLP never acknowledges the “modalities” and “submodalities” as related classifications, but the fact is that VAKOG categories are the presupposed modalities that submodalities refer to.
As a learner of NLP, you have to be mindful that your ability to use submodalities has nothing to do with understanding the representation of a “modality” – it’s irrelevant. Focus on the elements of submodalities and explore them deeply.
Play around with analog and digital modes of shifting submodalities. As a practitioner, you might be doing this in your own mind. Yet, you also need to master it by applying these shifts of submodalities in the minds of others, and facilitate that process.
“Make the picture bigger and brighter” affects submodalities as much as “instead of looking out through your own eyes, stand far away outside if yourself so you can see yourself”. While linguistically, most proficient individuals in English will find a way to describe this precisely, new practitioner must learn how to phrase their submodality shifts appropriately.
I’ve heard many people say things like “can you make your picture brighter?” (connotes uncertainty, especially with a typical beginner’s upward inflection which takes power away from their langauge) which defeats the purpose of the submodality shift: you want to use language that is certain: “make your image brigher now”. Or, if you choose a Ericksonian style, make it hypnotic: “I wonder how differently it feels when your image gets brighter now.”
Practice by recognizing your own STATES. You’ll know it works when you calibrate to the person’s response of you.
