Is what he says grammtical?

Yes, natural English.

What I don't understand is why he says "in the way". I'm having trouble making sense of the sentence. Would you tell me what he's trying to say or rephrase it so I can understand.

Each perspective creates a different effect. (I can't see why you would continue the sentence)

Thank you

eg Each different camera position creates a different effect in how you're trying to show your subject.


I agree that you could just say
Each perspective creates a different effect.

But he is speaking casually without planning his sentences carefully before he starts to

I guess it depends on the person speaking.

Could I switch 'in how' with 'as to how'? Would that make it more grammatical written?
Each different camera position creates a different effect in how you're trying to show your subject.

Thank you for your help

in the way and in how are both OK grammar.

as to how sounds awkward to me.
