How to describe most general EM- field in terms of photons? Is there always discrete number of photons? If EM field is given in terms of

a)EM-vectorfield:

E

_{x}(T;x;y;z) ; E

_{y}(T;x;y;z) ; E

_{z}(T;x;y;z) ; B

_{x}(T;x;y;z) ; B

_{y}(T;x;y;z) ; B

_{z}(T;x;y;z)

for any x,y,z and one T.

b) potentsials and loren(t?)z gauge

then what are momentums of photons?
