To push one stop you set the film speed to 200 instead of 100, and you *make sure* to tell the lab to process +1 stop.
Be careful with metering the light under those conditions as that is probably the most difficult.
Don't let the light of the sky fool you.

On most cameras, you can override the automatic ASA rating of the film (done by the DX code on the side of the canister). For 100 ASA, for example, pushing one stop means you manually set the ASA to 200. Pushing 2 stops would make you set it at 400.
After you've shot your film, tell the developer to develop it at +1 or +2 stops, as they must use different development times accordingly. This also means that if you want to push a film, you have to do the same for the entire film, not just a few frames.
Pushing any film one stop can usually be done with a minimum of loss of quality. 2 stops may be stretching it, depending on the film. Provia pushes quite well. I haven't tried Sensia.

I have pushed Sensia by 2 stops on an occasion when I was desperate for something faster, and the results were acceptable, so there should be no great problem with pushing it by a stop.
Bear in mind that almost all labs will charge you extra in order to push process the film for you. And you MUST tell them, and mark CLEARLY on the can "PUSH +1" or "+1 STOP" or else you'll get back a film that's all precisely underexposed by a stop.

I shot of a roll of K64 and most of my photos turned out very dark, so I've tried to take one photo at 64 ASA, and one at 50 ASA of the same subject at the same time. Will the 50 ASA shot turn out very underexposed if the film is developed normally?
