I have an idea for a project that involves taking photographs of everyday scenes in my house. Some of these pictures can be taken using ISO 100 film but scenes with people in them will probably require up to ISO 1600 film. For exhibition purposes, is it better to shoot all photographs with the same (or near) ISO so that there won't be too much of a difference between clean and grainy pictures? For example, the first photograph is a picture of my wife taking a nap. It is very clean because it can be shot using ISO 100 film. The next photograph is of my wife turning the pages of a book under lamp light. This would be very grainy because high ISO film is needed. Would putting these two photos together be a presentation faux-pas or does it not particularly matter?
