Artfully arrange the smoked salmon slices along two sides of a square platter. Arrange the lemon slices down the middle of the platter between the salmon slices, and spread the red onion slices over the lemon slices.
Scatter the capers over the top of the platter, and place a small bunch of dill under the lemon slices at the top. Sprinkle with the pepper.
