when done I launch Lightroom and import the same way I always do, LightRoom recognize the gps tag.ĮDIT: gps4cam support DNG files as well as JPG's. the latter is awesome for traveling where you want to know this was paris but don't care what zip code you are in, as the cell tower positioning uses no more power than the phone normally do.ĮDIT: My workflow is slight bit different, when processing, I select from and to folder to be the same folder on the card, the result is that the gps4cam software do not move the images but only edits the exif data to add the gps position. The iphone app can be adjusted to save power, do manual position capture, I like a fairly accurate position and have selected 1 minute intervals, the default is 5 minutes and there is a powersave function using cell-tower position to get you in the general area without turning on the gps. ![]() More details than you want - really, you can stop reading here. gps4cam have no control panels and no required finetuning. The most beautiful part of this app is that there is really nothing else you need to do, if you have experimented with geotagging software you will know these are involved big systems with time adjustment options, file import from different devices etc. So the app capture the gps info, save it and generate a QR raster code when you export, the trick is that this code updates every 10 seconds, and is time aware, so you could wait a week before photographing the code and it would still be correct, because when you photograph the code, the code contains the data to know when it was photographed, this is the key to this app, next the laptop app will search your image folder for the picture or pictures of QR codes, it will then match the code time-stamp with the camera capture time and then process the gps positions accordingly. Done you have geotagged your images and they will now show up on maps in picassa flkkar iphoto etc, in lightroom there is a position info click to go to google maps. Next - insert the card in your choice of laptop, open the gps4cam app, locate the card to process, and also locate a output folder, click GO. I capture the barcode with a 35mm or longer M lens, this is enough for the code to work, but I still prefer to use a 50-75 for the frame so it get a little more resolution it make me feel better. put the phone down and take a sharp picture of the screen. At the end of the day, tap EXPORT" This will bring up a advanced barcode called a QR code. How it works - Collecting the data - When you start shooting, launch the app on your iphone, tap "start a new trip" and forget. These two elements are the number one headache involved with geotagging for most users. to some it matters and to others its a complete waste of time, I shall not argue with taste and priorities at all.Ībout a month ago I became aware of the iphone app gps4cam, it is simply a life changer in terms of geotagging.! the guys behind the app have changed the way the track-file is transferred to the laptop and also how it is synchronized with the camera clock. Some here may know that I geotag most of my images.
