First, is "poster" the correct name? What I do is shoot a portrait, or a macro shot of a common item with a lot of white space in which I can add text. Then I'll add a poem or an anti-suicide message, etc.
Second, can you suggest any sources where I can find a plethora of examples of such photography? I want examples to learn from.
Third, can you suggest any great resources (e.g. textbooks) that would improve my ability to do this? I'm asking broadly: it can relate to photography techniques for this, to rhetoric, or etc.
