Using the database of Photometric Atlas of Northern Bright Galaxies, the spatial orientation of 220 bright isolated field disk galaxies (41 S0, 174 S, and 5 Irr) in the Local Supercluster (LSC) has been analyzed. The sample of field galaxies is constructed by selecting disk galaxies with cz <= 3000 km s-1 and excluding all galaxies of the groups or clusters of at least three members. Emphasis is placed on exploring morphological dependence of orientation of field galaxies. Main results are as follows: (1) The distribution of orientation of spin vectors of bright field disk galaxies of LSC is found to be significantly anisotropic and different from that of the Virgo member. (2) Orientation of bright field disk galaxies is morphological dependent, and therefore the process of formation of galaxies is as well. The distribution of spin vectors of the lenticulars, of which spatial distribution is most concentrated toward the LSC plane, is significantly anisotropic, and they tend to lay their spin vectors parallel to the LSC plane, while merely a weak tendency of laying spin vectors parallel to the LSC plane is found for the spirals superposing on background of the expected isotropic distribution. This hints that the process of formation of galaxies might also be morphology dependent; bright lenticulars and spirals might be formed by different processes relevant to the formation of LSC. (3) The projection on the LSC plane of the orientation of spin vectors of field galaxies does not show any tendency of pointing toward the direction of the Virgo center. (4) Field galaxies may serve as a better probe to detect the information in early universe.
