Many photographers will automatically place their center of interest in the middle of the picture. I prefer off-center placement for most subjects because it gives the viewer a better chance to compare and contrast elements within the picture. For example, in this shot of a Chukchi house, I am trying to make the point that it must withstand some of the most severe weather on earth. Their homes have no landscaping, and can't hold a coat of paint. Yet some of the Chukchi, such those that live in this house, manage a bit of decoration by putting plants in their windows. The off-center placement of the window allows for a stronger comparison with the crumbling siding on the right.
