final project proposal brainstorming

boundaries/environments/public v private/physical presence of people-I want to explore all of them but how and where do i begin---as far as my project for my black&white class goes -- i have to shoot 15 rolls of film and come out with 15 prints -36 exposures per roll-I want to show through the objects that we interact with a presence a sense of history -- and very possibility a time lapse would be best suited -I plan to photograph the same 5 locations throughout the course of a day within several days. I want to show the passage of time with the element of the human effect on a space. Albeit, it is an already established domestic environment as opposed to a natural environment.-will i be replicating the same position at each time of day or would it be ok if it were approximate?-to replicate the same exact circumstances within each grouping--is it more about me approaching a space or is it more about the space-i don't consider myself to be a technical person-- should that be part of my consistency? part of my process--that it is inconsistent? Structured but also not rigidly so. I think I could get away with that?!What do you think?
