I specify the same directories as input and output to store GPS data directly on the pictures on the SD card.I can only assume that Flickr is looking at the time the file was modified with the GPS data - but then I have made subsequent adjustments in Aperture and this modified time isn't carried though - it's very bizarre! Aperture still reports the original capture time.But as it stands now, I heartily recommend gps4cam to any iPhone user who wants to geotag automatically their pictures taken with another camera. I hope that the cons will be fixed in future releases. desktop application takes too long to process pictures and store GPS data.desktop application's UI needs more attention (I would prefer a native Mac application).trips can be exported as GPX (and visualized in Google Maps, Google Earth, etc.).unobtrusive and configurable iPhone application.If anything bad happens, it is my fault, I explicitly told the application to not warn me anymore. Instead, the application should let me check a box to say that I don't want to be warned next time and remember it. Every time, the application asks me if I am sure to do that and I must confirm. I put GPS data directly in the pictures on my SD card before I import them. The desktop application also needs to improve the user experience. one QR code) in the pictures but this will not work if there are many of them. This would work fine if there is only one "trip" (i.e. One way could be to let the user chooses the QR code picture (as I propose in the mock screenshot below by using an Image Well): I suppose the performance could be improved by identifying faster the QR code picture. I don't understand why it should take several minutes to perform these 3 steps (for a trip where I took only 40+ pictures). copy the pictures and store the GPS data in their EXIF metadata.retrieve the GPS data from the QR code picture.analyze the pictures (to find which one contains a QR code). The UI is not consistent with the OS (the progress is shown with a modal dialog window instead of a sheet or a progress bar) and it is too slow.Īs I understand it, the desktop applications takes 3 steps: It is a Java application, I use it on my MacBook and it does not feel at home. On the opposite, the desktop application needs more spit and polish. It is a pleasure to use it and I haven't noticed a specific battery drain. The iPhone is simple, non-obtrusive and a steal at 1.59€ (or $1.99). The last step to do is to use the desktop application which reads the QR code and put the GPS data in the other pictures' EXIF metadata 1.įinally, I can import the pictures in Aperture or any other software and voila! My pictures are (almost automatically) geotagged. The fantastic idea of using QR codes is that there is no need to synchronize the iPhone and camera clocks: the QR code generated by the iPhone and shot with the other camera allows to know the clock difference between the two devices and deduce where the camera photography were taken. This picture contains all the GPS information captured during my trip. The app is configurable and you can specify the frequency, to use GSM to triangulate the position instead of GPS (useful when abroad), etc.Īt the end of the trip, when I am done shooting, I export the trip which generates a QR Code. Periodically, the app will capture my GPS location. The app supports multitasking, so I can exit the app, put the phone in my pockets and not worry about it anymore. When I go outside and start shooting, I just need to run the iPhone app and start a new trip.
