    Default Turning off flash exposure compensation in GH1

    Hello,

    I love my GH1 for travel. I use it in automatic mode 99% of the time.

    I'm also using a device called PhotoGPS that attaches to the hotshoe and records the coordinates via GPS whenever I take a photo.

    The only problem is that whenever I attach the PhotoGPS to its hotshoe, the GH1 thinks that an external flash is attached and will underexpose my photos.

    How do I turn flash exposure compensation off?

    Thank you.

    Hello Ahmad

    Can you turn off the flash in the control panel or menu?

    Look for the symbol that looks like a combined no entry sign and lightening bolt! You may have to switch to P-mode otherwise it will probably default to having flash on in AUTO mode.

    Hope this helps.

    I don't think there's any way to get the camera to effectively ignore the flash, on reading a discussion about this on DPR the camera will not go above 1/160 with the photoGPS device.

    Alistair: Yeah, I looked everywhere and couldn't find an option like that, so I thought maybe I'm missing something.

    John: What a disappointment. The combination of GH1 + PhotoGPS was really elegant and promising. Thank you for your help.

    I bought a conventional GPS logger to use instead.

    This is the thread I was thinking of, it's a bit longer:

    I hadn't heard of the device before and really liked the sound of it when reading the forum topic, I'm really disappointed it doesn't work properly with the Panasonic G cameras as those are the ones I'd use for travelling. When I was on holiday in the US earlier I really wished I'd had a GPS logger as afterwards I'd forgotten where I was for some photos.

    It's such a shame that my phone camera takes geo tagged photos while my 'real' camera doesn't.

    Why not run an application on your phone to track your location based on time, then, compare the times in your phone to the times of your photos taken. No need to have the camera connected or physically touching your GPS device.

    I've heard of devices that work with any camera, that do this. You can keep it in your pocket, after shooting, when you get home or to the office, you put your card into the device and/or the computer, and it annotates your EXIF in the photos with additional GPS information.

    I see no need why a device must sit in the hot shoe.

    It's just that the way PhotoGPS works is a bit different than conventional GPS loggers and it has to be in the hotshoe because it only records satellite data when a photo is actually taken.

    I use an iPhone and there are applications that allow me to use it to records a GPS trail, but they drain the battery and they cannot run in the background so they are a bit cumbersome to use when I'm using the phone for so many other things.

    What a pity. I've ran my Google Android powered G1 (phone, not camera), with Bluetooth and GPS on, whilst tracking and playing Pandora internet radio. I can run it for the majority of a day like this if I wanted to, before running out of power. It can still receive calls during too. It truly is a does-everything device.

    Perhaps if tracking is important to you, I'd look into a non-hot-shoe tracker. I can see how the hot-shoe connectivity can give you coordinates accurate to a fraction of a second, but is that really necessary?

    I dunno ... I don't use a GPS unit at all, don't see the point. I know where I am when I take photos. Or when I'm driving, for that matter. I read maps. ;-)

    But if you have a GPS unit and want to log where you are, what's the big deal about turning it on and capturing your coordinates when you stop to take some photos? Do you really need the resolution of where, precisely, you are at the instant of exposure? Do you really go out into the wilderness where there are no landmarks or points of reference to recognize your location from?

    I think more use of these things are incited by marketing spin than for any real, practical advantage. I have a hiking compass and thermometer in my travel kit ... good survival gear ... and I've never once had the occasion to have to use them.

    Sorry to sound like a luddite. I'm not, I just don't see the point of burdening myself with more Stuff unnecessarily. ;-)

    thebinaryman: yes, I already got a regular GPS logger from Qstarz (model Q1300S).

    Godfry: it's not about precision, it's just that seeing my travel photos pinned to a map made it much better to relive my trip after coming back home. I wouldn't have bought into it until I saw it myself on the photos I took with my phone.

    If you're going to match up your photos and routes to satelite pictures then precision is very important plus I'd much rather have a small device doing the logging automatically without distraction and allow me to enjoy the walk/travel plus the photography. On a trip to the US earlier in the year I covered a massive distance and was on the move most of the time, it would have been far too tedious trying to log each location to work out where the photo was taken so I regret not spending more time looking into GPS loggers.
