Sooooo....when using the wider prime (e.g. 35mm) in horizontal/landscape mode and you find that your framed photo is the vertical/middle section of the horizontal, THAT is the clue to shift to the next longer FL (50mm) to use THAT prime in a VERTICAL/PORTRAIT mode to make use of most of the negative/sensor...
No, that's the clue to either move closer or change the composition. FL change will result in a perspective and visual depth change.
