Janine, Exposure won't be correct no matter how you develop your film. The best some pushing can do is raising the contrast from shadows, probably very weak due to under-exposure, to medium and higher values. As a beginner, you may not be quite sure about your metering thecniques, so I'd suggest you a 50% increase on development time and light a candle for some "superior help". Don't be sad anyway, for these accidents sometimes bring real good pictures. Good luck!(posted 8471 days ago)Cesar B.
