define what you mean by 'see'.

Great Bustard needs to understand that if two image areas seem to show equal numbers, then, a wide variety of input "exposure as in photons" could have generated them.

Not the point. You are putting about you that people are using ill defined concepts, then you come up with the extraordinary claim that we don't see photons. Clearly, we do under any normal definition of 'see'. Of course, we can dig beneath those ordinary definitions and claim that we don't actually 'see' the photons, but the effect (electronic or electrochemical) of them, and even then we don't 'see' that, what we 'see' is a pattern of neurons firing, and of course whet is the process of 'seeing' in any case, except just a repeatable patter of neuron activity. It's always possible to deconstruct a sensible statement to make it a nonsense. Whether it is actually useful is another question.

So, he can't just go around and keep saying naive and simplistic claims about so and so equivalence in photos and same exposures generating equivalent images, etc.

I think you'll find that he can.
