I finally got a new digital camera with built-in GPS before my final trip to Argentina, and I *love* that function. (I read somewhere that they're predicting that a GPS function will eventually become a standard part of all but the cheapest of cameras, including compact cameras.) I also got a couple of extra batteries from Amazon.com and a car/wall charger that adapts to voltages between 100 and 240 V for really cheap, so I didn't worry about how quickly the battery got used up. Even on a very busy day I never used up more than 2 of the batteries, and I could recharge in the car. I also like how it not only indicates where the location of the photo was, but also which (compass) direction I was facing when I took the photo, and the _local_ time when I took the photo--all automagically! But I wanted to mention that if you have a smartphone with a GPS in it (like the iPhone), you can get an app that automatically does what Jim described that he does manually. After synchronizing the clocks on your camera and phone (and it doesn't have to be exactly to the second), you turn on the app and every time you take a photo, you merely press a button informing the app that you just took a photo. After getting back to your computer, you download all your photos and a file that your app produces, and a free application on your computer from the app maker takes the file, runs through all your photos, syncs up the times (based on the nearly synced clock times and separation times between photos), and then adds the GPS data to the metafile data of each photo, after the fact. In any case, I'm wondering if Diane will have time to upload photos of her trip to some site or write up an article for the PBS newsletter?? --Lee Poulsen Pasadena, California, USA - USDA Zone 10a Latitude 34°N, Altitude 1150 ft/350 m On Oct 27, 2011, at 12:35 PM, J.E.
