By means of contour integrals involving arbitrary analytic functions, general solutions of the zero-rest-mass field equations in flat space-time can be generated for each spin. If the contour surrounds only a simple (respectively, low-order) pole of the function, the resulting field is null (respectively, algebraically special).
