Just ask the lab to "push one stop" when you send it for development.

Otherwise, if you still want to develop it as normal, then you can either set the EV compensation to +1EV, or manually increase the exposure by 1 stop (eg. f/8 to f/5.6, or 1/250s to 1/125s). But then there is no reason for doing so, and it would be weird.

no need to compensate if you want the metering for iso1600 (usually faster shutter speed). But when developing need to tell the lab to "push one stop".

Also, note that your friendly ( or not so friendly ) neighbourhood lab may not understand what is 'push 1'. And then usually you'll be charged more. Looking at the RGB pricelist that I'm holding now, it says 50% more, which means $3.70 + $1.85 for negative film.

ColorLab charge me $6.50 for push-process!!

But the print contrast very nice!!

My friend like it!!
