You lose your shadows but the rest is just fine. Things start to fall apart at two stops. But remember, the "ISO" speed is the "maximum" speed that the manufacturer deems acceptable (minimum exposure, nearly zero upward latitude.) ISO 400 film would have been an ASA 200-320 film, which would easily go two stops over the ASA assignment. So when pushing an ISO stop, you are truly pushing the process beyond what is already deemed the minimum. But one stop seems to work just fine for me. JB
