Playing Tag Part 1

If you’re at all like me, it is quite easy to come back from a birding trip with thousands of pictures.  Once home, organizing the photos can take many dimensions (and indeed be a topic for a book, not just a blog post!)  One important element of photo cataloging to consider is keeping track of locations where bird photos were taken.

A traditional way to keep track of photo locations is through field notes.  Often I can look at one of my bird photos and remember the spot where I took it, especially if I go there a lot.  By pulling up the photo’s date I can also look at eBird to see what checklist and location I have associated with the species photographed.  There are many birds I’ve photographed that left a big enough impression on me that I can find the exact square meter on Google Earth or Google Maps where the target was acquired.

Some birds leave a big enough impression to remember their exact location without geotagging or even written notes, such as this Barnacle Goose in Grimsby, Ontario, December 2009.

But as my photo stock grows and my memory diminishes I really appreciate my photos telling me where they were taken.  Enter photographic getotagging, basically the ability of a camera to associate GPS coordinates along with the other metadata recorded with each digital image.  With geotagged images, I can just pull up the location data and see precisely where my camera was positioned for the shot.

Birding jaunts often take us to places without familiar landmarks, or any landmarks at all!! But I know exactly where this Cook’s Petrel was: 33° 25′ 21.4″ North, 120° 46′ 55.9″ West, thanks to my camera’s GPS receiver. Offshore from Santa Barbara, CA, July 2009.

Interestingly, improved features don’t always filter from the top down in the camera industry.  Naturally, some innovations first show up in top-end DSLRs before finding their way “down” to more affordable price points in successive generations of camera body offerings.  Advances like reduced noise in sensors at high ISO and more sophisticated metering and autofocus systems would be examples of top-down improvements.  But built-in geotagging has been frustratingly slow to appear in DSLRs (even the most expensive pro models) despite its ubiquity in smart phones and ready availability for years in selected digital point-and-shoot lines.  For a while many DSLR cameras have had the ability to support geotagging with the addition of aftermarket GPS accessories, but at additional cost & bulk (not to mention your flash shoe being occupied by a GPS receiver and a stray cable to snag stuff & generally annoy whenever possible.)  I’ve used an external GPS receiver through several generations of camera bodies and have come to rely on it, but the outlook for integrated geotagging in DSLRs is getting better all the time.

My trusty rig with a GPS receiver mounted on the flash shoe & connected to my camera body with a cable. Wouldn’t it be nice if all that was built into the camera body?  I have a feeling this is coming soon to a DSLR near you!

In November Nikon will join Canon by each offering a DSLR body with built-in GPS receiver (Canon’s EOS 6D and Nikon’s D5300.)  Sony also has a couple of DSLR bodies with this feature (the a77 & a99, though Sony doesn’t seem to have the birding market penetration of Canon & Nikon yet.)  I hope these are the vanguard of many more DSLR body choices soon to come with integrated GPS receivers for geotagging.
