GPS Tagging DSLR Photos With iPhone


Originally uploaded by Tukay Canuck

Call me a cheap b%st%rd, but I don’t want to invest $200+ to get the Nikon GPS unit, which to me is just a luxury.

I did some research (read: Google), and found a way to inject GPS data from my iPhone.

The work flow to accomplish this is the following:
– Start up an application on the iPhone called RunKeeper
– Take pictures
– Stop application
– Upload photos to Lightroom on PC
– Download GPS information from
– Use jFriedl’s GPS application to tie in the GPS coordinates with the photos

RunKeeper is a free iPhone app.
jFriedl’s GPS app has a free trial, and continues to work for free with some limitations. (It’s donationware, so it is inexpensive if you decide to use the full functionality.)

The great thing is that as long as your phone and camera’s clocks are in sync, you can keep the application running on your phone and it will keep track of where you were and at what time you took your photos.

This is my first attempt, so I am not sure how much of an impact running the GPS on the iPhone is on the iPhone battery.

The instructions that I followed is located here

First you need to log into the website (free to use), and download your GPS history – a .GPX file

The jFriedl plugin is activated by selecting all photos taken while you ran the Runkeeper application.

Browse for the GPX file that you downloaded to your computer.
I had to use GMT time as the time zone, as it seems that Runkeeper stored the history in GMT timezone (configurable?)

Click on the commit button, and the GPS coordinates get synced into the photo’s metadata, and gets updated with Flickr.

I tested the accuracy of the GPS coordinates, and it was bang on.

Obviously this workflow is pretty handy for photowalks, but I’ll have to see how long my iPhone lasts for. It’s a pretty involved workflow if you are intending to only GPS tag one photo – it would probably be easier to use Google Maps or the Flickr location tool

About Light (and Shadow)

49/365 Unbearable

It’s been a while since I blogged, and this entry will be short, but important.

The quality and direction of light has a huge impact on the final product.

These photographs of the same polar bear look quite different.

The first photograph was taken with diffused lighting (cloudy conditions) late morning.

Note the image looks quite two-dimensional, almost like a cardboard cutout.

The second photograph was taken in less cloudy conditions, at the end of the day with very directional light.

The light in the second photograph has a warmer colour to it, and the directional harsh nature of the light creates shadows that gives the second photograph a sense of dimension and shape.

We are three dimensional creatures – we experience the world around us in three dimensions, however photographs are two dimensional. Adding shadows to our subject allows the viewer to identify the dimension and texture of the subject.

Light and shadow isn’t always a good thing; harsh shadows aren’t always flattering for human subjects, and usually a cloudy day, such as in the first photograph, would be more aesthetically pleasing on a person.

We can’t control natural light, but we can be aware of weather conditions and the type of light we can expect at different periods of the day.
