Help with GPS adjustment

I thought I knew this, but I'm not having success. My camera is set to NY time, -5 GMT. I was shooting in Argentina, -3 GMT. My Wintec records GMT. Geosetter.

How do I set the adjustment in Geosetter to get the right time for each photo with the sync bet Geosetter and the Wintec files?

HOLD ON. Major error on my part (human.) My camera's time zone was set to London time from my last trip. Will try again.

Yeah. I always leave my camera, my GPS, and my computer set to my home time zone. Saves a lot of that kind of headaches (and puzzles the hell out of geeks who decide to look at the EXIF and figure out how I took that bright, sunny picture at 2 AM!).

Figured it out. I had not reset my camera clock to local time and it was off by three time zones, and was running slow. By correcting for the time zone and the few minutes difference in the time, I got each shot on the spot.

One simple way of getting a good match-up between camera time and GPS time, assuming you have a GPS with a display, is to take a photo of the GPS screen at the start of the day.

Thanks, Frank, a very clever suggestion, but my GPS has no visual display. I will assume that setting the camera time by atomic time will put me within a second or two of the GPS, even if the camera loses some time over the trip.

One nice feature of the Canon GP-E2 is that it'll set the camera time for you on any supported camera (except the 7D). Some third-party software will let you set your camera's clock from your GPS when both are connected to the computer, too.

I used to have (actually, I probably still have it somewhere) a GPS device like that. It was wonderfully compact, except for the fact that I had to take the manual with me everywhere because I couldn't remember if 'blink, blink, flash' meant that it was logging data or if that was indicated by 'flash, flash, blink'.

My BGT-31 has an LCD that's about 2x1 cm - but that's big enough.

Seems a strange design decision not to have a visual display! I am a retired offshore sailing instructor and the whole point of a GPS is to give the navigator a heads up. Either telling him/her there's a problem or simply reassuring, but both require a visual output.

That's the difference between a classic GPS device (tells you where you are, where you've been and helps you figure which way you want to go) and a GPS data logger (only tells you where you've been).

Good tip. Reminds me of slide film days when you sent film off by snail mail for processing. I always carried a handkerchief with my name and address. That was always the first frame on a roll. Over many years a couple of rolls got near lost by Kodak, actually were returned to the wrong customer, but made their way home in a few weeks.

Mine's a Wintec, which is the size of a quarter and weighs an 1 oz, and has a slot for an SD card. I put a 64 GB chip in, and now can have 20 million data points recorded at one per second over a long trip. I can leave it on all day and forget about it. That's what I did on this three week trips and every photo was recorded with long and lat successfully. As long as I remember to set the clocks on my cameras I should be OK.
