considering your profession, you must go for photojournalism. See, Cinematography is more of direction, dealing with scenes, frames, sets and movements, while photography is still. So going by your experience, go for photojournalism.

Both are the good options & depends on your interest & capability.

Cinematography is also far more collaborative than photojournalism. The differences between photojournalism and cinematography is that The primary role of the photojournalist is to be a visual storyteller By photographing, editing, and presenting images, but a cinematographer deals with relations between shots and between groups of shots.

The chief cinematographer supervises a second cameraman (or camera operator), who handles the camera; an assistant operator.

 

The choice should be yours but I would suggest you for Photojournalism as you are a travel Photographer.

 

Good Luck!
