Dear gps4cam users,
Here are the four most common mistakes submitted to the gps4cam support team. By knowing them and by reading the FAQ, you are ensured to have an optimal usage of gps4cam.
n°1 : The screenshot instead of the photo.
You have to photograph the generated QRCode(s) with the same camera you used during your trip. This is mandatory to automatically take into account the potential time shift between the camera time and the iPhone time. Please note that gps4cam cannot work with a screenshot of the QRCode.
n°2 : The trip that generates several QRCodes.
If the trip is long, several QRCodes may be generated during the export. In this case, you have to photograph every QRCodes. The number of dots under the QRCode allows to know the number of generated QRCodes. You can switch from one QRCode to another one by sliding your finger on the iPhone screen.
n°3 : Several trips in a same vacation.
Before gps4cam desktop V4.0:
It is possible to make several trips in a vacation and to use gps4cam desktop at the end of vacations. However, there is an important rule to respect in this case: always export and photograph the QRCode of a finished trip before starting a new one. If you try to export all your trips at the end of your vacations, it will be problematic since gps4cam does not look for QRCodes in photos which are in the timeframe of an already decoded trip (for performances reasons). If this rule was not followed, it is possible to make gps4cam desktop works fine, but you have to create one folder by trip and put photos of the trip and qrcodes of the trip inside.
After gps4cam desktop V4.0:
gps4cam desktop 4.0 offers three QRCodes search methods, that is why the preceding rule is not mandatory anymore. You can photograph all QRCodes of all your trips at the end and choose the corresponding method in gps4cam desktop preferences, or you can even manually select pictures where QRCodes are.
n°4: Camera time change during the trip.
A big advantage of gps4cam is that it is able to automatically manage the time shift between the iPhone time and the camera time without anything to do for the user. So please do nothing . You must not change the camera time between the beginning of the trip and the moment you photograph QRCodes after export.
