In micro stock photography, access and proximity makes you money. Having the image everybody wants, now or in future will pay off. But first you have to put yourself in a position to get the shots nobody else has. Get roving and put yourself in new venues to get new shots. Plot your micro stock trajectory along new paths.
Location shooting where I live (Burbank, California) is at a premium. Many places nearby like local businesses and public venues can be used for shooting scenes, but that unknown location is also great to discover. Many obvious choices can work against new productions because they are too expensive or difficult to obtain on short notice. Images of available or accessible locations for various interior and extior scenes are a microstock market all its own.
