Safely post your vacation photos while you're away, especially of your children

You're away from home on a “trip of a lifetime,” or perhaps just an ordinary outing to the summer seashore, but whichever vacation you're on, you've decided to post some photos of it, showing how much fun you're having. For family vacations, you decide to post photos of your kids for their grandparents, and the rest of your family and friends, to see and enjoy.

So, you pull out your smartphone or camera, and get some great images of your family on vacation, having the time of their lives. You log into Twitter or your Facebook account or Flickr, or Smugmug, and upload the photos.

“Does that make sense?”

“Is it safe to post vacation photos, which may include your children, to the Internet, while on vacation?”

Identifying your travel photos when you return home - Part III

The Photo Identification series, discusses one of the most classic problems of the vacation photographer, identifying one's photographs after returning home. When people look at their photos weeks after making them, it can be difficult, if not impossible to remember where each one was made, and what each images' subject is.

In Part I, low-tech identification methods were discussed, such as written journals, marking maps with photo locations, and using identifier photographs. In Part II,  hi-tech identification methods which are automatic or close to it, such as using GPS technology was discussed.

In Part III, I conclude the series with a discussion of software to input missing GPS data, correct already embedded data, and locate GPS coordinates for input into image exif data, and using only manually collected information about one's photo locations.

Travel Photography: Geotagging, Part 2

In Travel Photography: Geotagging, Part 1, I discussed what geotagging was, and why anyone taking photographs while traveling should at least consider it its use. Here in Part 2, I discuss GPS receivers and geotagging software.

The Global Positioning System (GPS) is a global navigation satellite system developed by the United States Department of Defense, and maintained by the US Air Force. It uses 24 medium Earth orbit (12,500 miles above the earth) satellites, each transmitting precise microwave signals, which enable a person with a GPS receiver to determine their current location, the time, and their velocity.

The satellites circle the earth twice a day, but at any given time, it's rare to pick up even the half on any side of the earth. Fortunately, you only need 3 or 4 satellites to use a GPS receiver to navigate. The signals sent by GPS satellites are not able to reach deeply through solid objects, such as buildings, but the system works well outdoors.

Until 1983, the system was not available to the general public, but after Korean Air Lines Flight 007 was shot down that year, after straying into the USSR's prohibited airspace, President Ronald Reagan issued a directive making GPS freely available for civilian use. Since then, GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, surveying, commerce, and scientific uses, as well as geotagging.

I remember getting my first GPS receiver, plus software to turn my laptop into road navigation system, years ago. It was so much better than reading maps. It could pinpoint your position as you traveled. It's comforting to know exactly where you are, while driving in a new area. Now, when traveling, I use a portable GPS device to get around (OK, I admit I have some maps as backup, just in case.)

When I first began to experiment using GPS with my photography, there were few GPS receivers built specifically for use with Nikon or other GPS enabled DSLR cameras. The one standout at the time was from Red Hen, however, it cost more than $600. I decided to build my own. Like many, I based my system on the Garmin Geko 301 GPS receiver. I modified the Geko to mount on my camera, as well as the Nikon MC-35 GPS cable, and necessary PC serial cable. The unit worked like a charm with my Nikon D200, but was somewhat unwieldy due to the cabling requirements. Last year, I purchased the Solmeta DP-GPS N2 kit, which is small, and pulls in signals much better than my homemade setup.

Over time, GPS technology has dramatically improved. Receivers are now built with new chip sets which have more ability to receive and decode the L band microwave signals sent by the GPS satellites. When deciding which GPS receiver to purchase for your camera check for:

• Compatibility with your camera.
• Size and cable specifications to determine usability.
• If the unit must be attached to the hot shoe of your camera, or if it can be held on the strap, etc. to free the hot shoe for use with your flash.
• If the unit is plugged into a camera port which is used for other purposes, if a splitter is available for simultaneous use of the port with another device.
• If it has it's own power supply (preferable) or uses power supplied by the camera.
• If it has a built-in PNI Electronic Compass, as some cameras can record the direction the camera was pointed when the photograph was taken.
• If it has an auto indoor GPS position fixed mode, so that it will allow the camera to use the last GPS position received, to store with photos taken, while the camera is used inside.
  
• The sensitivity of the GPS unit to receive data, even in adverse conditions such as bad weather, among tall buildings in cities, and amid forested areas.

When I recently checked on Cnet's download.com for geotagging software, there were 10 choices, but I know there are many other products available. Quality geotagging software can actually write raw data into each photograph's Exif data, however, for me it's more important for it to be able to pull existing Exif data from my photos and use it. After reviewing geotagging software, I purchased RoboGeo. When choosing geotagging software check for:

• The software must be able to read your camera's Exif data directly, edit it, add new data to it, and use it for mapping purposes.
• In order to create export files, the software must be able to pull the data directly from photos from a list of your choosing.
  
• Is the software capable of stamping the photos themselves on their face, if desired, with time and GPS information?
• Can the software use Google Earth to directly geotag photos missing GPS information?
• Can the software geotag photos from place names, or IPTC locations?
• The software must be able to create Google Earth KML and KMZ files to create maps of your photos on Google Earth.
• The software must be capable of exporting geotagged photos to Google Maps, Flickr and Yahoo Maps, MapPoint, Shapefiles and create DXF files to be used in 3rd party utility programs.
• The software should be capable of use in GPS Visualizer, an excellent personal mapping web site.

Some photo sharing web sites like Smugmug.com are capable of making their own maps via your photographs, if they contain the correct Exif data in each photo. Here geotagging software comes in handy to edit GPS Exif data, or add data to photos with missing or incomplete GPS data. If you'd like to see what one of these wonderful maps looks like go to my photo-site NSL Photography. Navigate to the nslphotography > Cities > Philadelphia, Pennsylvania > Philadelphia Photo Walk - Society Hill / Olde City gallery. Opposite the gallery name, click on the "Map This" button. There are 39 photos which will map, so it might take a few moments. Click on one of the green balloons with a face, of a photo on the right, and see what happens.

The map sure answers the question, "Hey, exactly where is that?" doesn't it.

Travel Photography: Geotagging, Part 1

Have you ever wondered what all the geotagging fuss is about, or what it actually is? Have you ever heard the expression, "Find your photos," and wondered what the heck that was all about?

Have you ever returned home from a long vacation, and started scanning through your photos, only to forget which church was which, or exactly where you took that great photo? We all have, at one time or another.

Year's ago I took detailed notes whenever I took photos on trips. More recently, I dictated the information into a digital voice recorder.

Here's the thing though, I can go on a trip for a couple of weeks and easily take several thousand photos, especially if they're wildlife photos. Not that long ago, on a "trip of a lifetime" to the Galapagos, I took more than 5,000 photographs in just a week of hiking, cruising, and snorkeling.

The best solution in the 21st century, I've found to record exactly where each of my photos was taken, is geotagging.

"Geotagging is the process of adding geographical identification metadata to various media such as photographs, video, websites, or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though it can also include altitude, bearing, accuracy data, and place names."

Geotagging photographs can be done manually or automatically. It can be accomplished via a GPS device, geocoding, geotagging, or Exif editing software. Some Point & Shoot camera manufacturers have added GPS modules directly into their cameras, while other cameras, especially professional quality DSLR's, are GPS capable and can have portable GPS devices plugged directly in to them.

Geotagging my photos has become a crucial step in documenting my journeys. It enables me to be able to precisely inform interested parties where the photograph was taken. By geotagging my photos I can easily use them to create a narrative of my travel experience.

Moreover, when I travel to places few have had the chance to visit, I can use the geotagged photos to help answer the question, "Hey, exactly where is that?" Using online mapping software like Google Maps or Goggle Earth, I can literally "map" my geotagged photos so everyone can can see the photo coupled with both topographical and geographical data displayed on the map.

My Nikon DSLR is GPS capable. It keeps GPS information in each photo's Exif data. I could enter the data manually, collected with one of those handheld GPS units, but that's just too much work, so I bought a GPS receiver for my DSLR. It's definitely the best travel photography accessory I bought last year!

I purchased the Solmeta DP-GPS N2 unit (from Nikonians) which plugs directly into my Nikon DSLR. Every time I take a photograph the camera pulls the GPS information from the Solmeta unit and stores it with the photo.

I use RoboGEO software which can read the GPS data (longitude, latitude, elevation) from each of my photos directly. I can then create a Google map which shows each of the chosen photo locations, or create a KML or KMZ file to import directly into Google Earth. Many photo display websites such as Google's Picasa, Yahoo's Flickr, or SmugMug can take your photos and map them for you in your photo area of their site, if the photos contain GPS data.

I highly recommend any traveler geotag their photos to enhance their memories of their sojourns.

Are travel photos on your online photo site safe?

Are your travel photos on your online photo site safe? Maybe not.

They weren’t for members of Digital Railroad, who learned on Oct. 29th that the site was going out of business and their photos would be lost forever if they didn’t act immediately.

Anyone who logged in to the photo site was greeted with the following message: “We deeply regret to inform you that Digital Railroad (DRR) has shut down.” The company had sought new financing, but their efforts failed. It turned out that Digital Railroad was able to maintain access to photos through midnight of October 31st, but after that, the site was closed and transfer of the photos to other locations impossible.

The vast majority of traveler and amateur photographers now take digital photographs. Even countless professional photographers, especially ones involved in newspaper and magazine photography (except fashion photographers) have made the jump to digital photography. About four years ago, I completely moved from film to digital photography.

I have a substantial photo site hosted by Smugmug. I have about 1,300 photos online, and I’m about to upload another few hundred soon. For me, my Smugmug hosted site is essential to my photography business. Through the site’s display of my work, I’ve sold many photos to a variety of clients either directly from the site, or from my library of photos, when clients became interested in my photography via the sites.

On Tripso.com forums on TalkingTravelers, members have pointed me to their online sites containing countless wonderful photographs of their travels. Showing your travel photographs online to friends and family is one of the top uses of Internet photo websites. Many travelers use Internet photo sites as their main repository for their precious photos, and have no copies elsewhere. After a while, for the average amateur photographer, the aggregate file storage size of their photographs exceeds the available capacity of their computer’s hard drive.

So what can anyone do to ensure they don’t loose their precious photographs preserving wonderful memories of great sojourns around the world?

Don’t depend on photography websites as your primary storage for photographs. The sites are not under your control, so you can’t depend that your photographs will be there forever. There are steps you can take, even if your computer’s hard drive doesn’t have enough capacity to store all your photographs:

1. You can print each photograph. The problem with this solution is that it doesn’t make it easy to make high quality duplicate prints, or computer displayed photographs later, if the original digital photographic files are lost or deleted.
2. You can put all your photographs on a CD or DVD for long-term storage. Archival quality CD blanks are readily available. However, there are still questions about the longevity of archival DVDs. The real problem with this solution is that according to how many photographs you take, the number of CDs and DVDs in your photographic library may become unwieldy.
3. You can put your photographs on external hard drives. Currently, this is the solution I follow. While I use my Internet photo site for display of some of my photographs, to show them off to clients, as well as friends, family, and fellow travelers, all my photographs are on external hard drives connected to my computer. I use Seagate FreeAgent Pro units, soon to be superseded by Seagate FreeAgent XTreme external hard drives which have a triple interface, including USB and Firewire connections. I connect these hard drives to my computer via Firewire due to its high transfer speed. I use duplicate external hard drives to have a backup of my photos, as I can’t afford to loose my work. (Seagate 750 GB FreeAgent Pro Triple Interface External Hard Drives can be purchased today for as little as $135.)
4. Skip media that’s impractical. I don’t consider long term digital photograph storage on other media such as memory cards, or removable cartridge drives to be feasible, as they don’t have long term viability.

If you currently use Internet photographic sites as your primary digital photographic storage location, I strongly suggest you consider and take advantage of other alternatives.
