We introduce a new background field method for N=2 superspace. (We treat projective hyperspace, but similar remarks apply for the harmonic case.) In analogy to N=1, background gauge fields are in the real representation, so the lowest-dimension potentials are spinor and the usual non-renormalization theorems are manifest. Another consequence is that the R-coordinates disappear from the effective action.
