We present u,b,r & i galaxy number counts and colours both from the North and South Hubble Space Telescope Deep Fields and from the William Herschel Deep Field. The latter comprises a 7'x7' area of sky reaching b~28.5 at its deepest. We show that simple Bruzual & Charlot evolutionary models which assume exponentially increasing star-formation rates with look-back time and q_0=0.05 continue to give excellent fits to galaxy counts and colours in the deep imaging data. With q_0=0.5, an extra population of `disappearing dwarf' galaxies is required to fit the optical counts. When we compare the observed and predicted galaxy counts for UV dropouts in the range 2
