Help identifying weeds to photograph.

Am working on a project to photograph some weeds in my area as pictorial reference for allergy patients. I can find pictures of specimens, but I must use original work. When I go out weed hunting, I cannot tell the difference between mustard or golden rod or ragweed (for example). Any ideas for a field guide, including a budding botanist? This is for Southern California.
