gps4cam doesn't require that.Geotagging, or the act of applying detailed geographic coordinates, to my photos is exceptionally important to me. Most geotagging apps will give you bad results if you don't keep your camera time very accurate. Sure, it's a nice idea to keep your camera time somewhat accurate, so that you can use the camera time for other things (like searching for a picture months later), but rarely do you need to ensure that your camera time is accurate to the second (or even minute). If your camera time drifts a bit and you're not obsessive about fixing it every time you care about locations, you're not screwed. If you travel to another time zone and don't change your camera to that new time zone, you're not screwed. So, if you forget that it's daylight savings time, you're not screwed with gps4cam. Because gps4cam encodes the GPS time in the QRCode you take a picture of, gps4cam can determine the offset between your camera time and the real time without you having to do anything. That is the major problem with most other geotagging systems that I investigated - if the camera time was off, then your photos were tagged incorrectly. You missed the most important part of gps4cam relative to other systems - you don't have to set your camera time to the exact GPS time. For more information please visit the Geotag Photos website.
GPS4CAM PRO PRO
The Geotag Photos Pro iPhone App is available from the iTunes Store for £2.49. Geotag Photos Pro iPhone App Cons Demanding on the already short battery life on the iPhone Geotag Photos Pro iPhone App Pros Cheap and reliable way to geotag photos The Geotag Photos Pro iPhone App is reliable and an easy way to geotag your images. Both methods are easy but it's likely you'll prefer one method than the other and this is the main decision to make. Both allow it to be exported by GPX but the main method with this app is via their website, the gps4cam app displays the data in an image which is then read by the geotagging software. The main difference is the way you get your data from iPhone to computer. The end result is the same as the gps4cam app, your images have all been geotagged. By clicking on the red marker, you can see the location the image was taken on the map. The image below shows a set of geotagged images in Picasa. The image on the right shows the exif data of an image taken on a Kodak Easyshare Touch M5370, which isn't a GPS camera, but thanks to Geotag Photos Pro now has GPS data. If you would prefer, the data can be exported by GPX to email or iTunes, rather than having to upload via the website.
GPS4CAM PRO SOFTWARE
Once you have created an account and have the software this becomes a very speedy operation.
GPS4CAM PRO DOWNLOAD
This will then lead you to download the software which geotags your images automatically. To then apply the geotagging data to your images, you need to upload to the Geotag Photos website, where you are required to create an account.
GPS4CAM PRO UPDATE
You can manual update the GPS location at any point. You can then lock your phone and enjoy your journey. Once this is set, you hit record and the app will find your position. When you click "new trip" you are asked to give the trip a name. Although it's easy to do without the app, it serves as a good reminder to ensure your camera is set correctly. One extra feature which wasn't on the gps4cam app is an area which displays the time and date you should set your camera to. You can also set a minimal position change, from 10 metres to 1km a various intervals. The more frequent you set it the more power is used, but you get much more accurate geotagging. To help make the most of your battery life there are a range of autologging options, from every change in position, to every 30 seconds, 1, 2, 5, 10, 20 minutes or every hour. When constantly using a GPS signal, required by the app, you will run down your battery quicker than normal.
