We have carried out a deep CCD survey of `blank', i.e. non-cluster, fields near the South Galactic Pole, in order to search for field low surface brightness galaxies (LSBGs). We have detected over 500 objects in a total of 1.2 deg^2 which have low observed central surface brightnesses, mu_0 below 22.5 Vmu, and exponential scale size greater than 2 arcsec. The faintest have mu_0>=26.5 Vmu. The surface brightness distribution appears to increase towards the faintest surface brightness bins. A variety of arguments, including a study of their clustering on the sky, imply that the large majority of these objects - which constitute only a small fraction of the total faint galaxy sample - are genuine LSBGs at low redshifts, and not cosmologically dimmed distant giants. The number density of field LSBGs with scale sizes greater than 0.8 h^-1 kpc is estimated to be approximately 1h^3 Mpc^-3, an order of magnitude greater than the density of `normal' galaxies brighter than 0.1 L_*. This is very similar to the ratio of LSBGs to giants seen in a previous study of a particularly spiral-rich cluster.
