  The camera analogy can help highlight an important shift.  Imagine that our camera is damaged and its resolution in part of the screen is diminished. This newly acquired constraint will be reflected in every subsequent photo, and this low-resolution element would be an ‘apriori’ feature of each photo: it would be a contribution of the representational structure of the camera, not of the scene. The point is that the key feature of Kant’s framework elements is the role they play in structuring experience, not whether they are present as part of the initial condition. In principle, acquired changes could play this  role.[14]  In this respect, Kant shifted the epistemological focus away from genetic questions of origins to questions about sources of warrant.  It could be argued that this shift moved innateness to the periphery of philosophical concern until its 20th century revival.
