I mean, the idea is, that the tarriffed stuff becomes less attractive compared to the non-tarriffed stuff due to the higher price, so less people will buy it and instead the nationally produced alternatives thus strengthening the national economy and and weakening the tarriffed ones.
Of course that can only work with stuff that has nationally produced (or at least non-tarriffed) alternatives.
Most phone cameras also have a much wider focal length than our eyes though, which makes faces look a bit skinnier. I definitely look better in wide angle than in reality or telephoto.
