I must admit, in my younger days, being really eager to please the client and to secure the work, I would share my ideas and concepts openly only to have them use another photographer.
But now I would only get involved when they have a layout and clear concept put on paper and shown when we meet and that I am the photographer doing the shoot.
Any agency who is genuine in using you will only reveal the concept to the photographer they are using for the image. But do understand even after all the planning the client may sometimes cancel the whole project at the 11th hour.
I believe that a photographer should always have some grounding in idea/campaign/CTA conceptualisation and be in the know of current trends in cultural industries. It will help in communication, and that is very vital.
