One of my big passions is photography. I’m quite old-school as I mostly use a big DSLR, post-process my shots on the PC and upload some keepers to Flickr. But I’m also using my mobile phone camera more and more. Nothing beats the convenience of snapping a shot and being able to upload in one sweep. Some people, like me, just have a mental barrier to overcome, the technical perfectionism. A shot can be fun and interesting even if you haven’t spent hours tweaking it. I’m working on that…
Sharing photos on the net is fun, but did you know how much a single picture can tell? I’m not talking about the traditional “more than 1000 words” here. I’m talking about metadata. This is invisible data that describes the content and is embedded in the picture file. This is some of the data that a photo can contain:
All this data does really provide a lot of added value. You can automatically have shots sorted by capture time, you can plot photo locations on maps, find all shots taken with a certain camera or lens, and so on. The possibilities are almost endless. But metadata is like all other great things, it can be used and misused. The downside is naturally privacy.
I did a quick test with my Nokia Lumia, which is a Windows Phone -device. It turned out that its camera embeds the date and time, photographic parameters and the GPS-location automatically. But data about the owner is not included. This data is also kept when using all share-options that I currently have available; mail, Flickr, Facebook, SkyDrive and DropBox. There’s no setting anywhere that would control this behavior. In theory, I could reveal my exact location every time I upload a photo.
But this is not the full story. The service that you upload to can also decide how to process metadata. Facebook strips it altogether. This design was probably implemented to save storage space, but has a positive side-effect on privacy. Photographers who are interested in the photo parameters are however not happy. Flickr uses a different strategy. Metadata is extracted and used in the interface. You can decide if you want it to be showed or not. Users can also download smaller picture files without metadata, or the original with all data intact, if you choose to allow it. It’s quite natural that Flickr is more advanced as it is a site focusing on photo sharing.
So what should I do about this?
To summarize. You do not necessary have a privacy problem with metadata in photos you share. It depends on many factors. The device you take photos with, the software you use to process and transmit the shots and finally the site where they are published. And naturally your own privacy expectation, what data are you ready to share? But the most important point is to be on top of this yourself. Don’t leave it to chance. Check what you share and make up your mind if it’s OK or not.
An exercise for you. Download the photo file in this post and check what kind of metadata you can find in it. It’s taken straight from my workflow program on the PC, no data removed.
PS. Also keep this in mind if you feel tempted to cheat about when and where a shot is taken. You are unlikely to get away with it if you have photo-savvy friends.

In Finland, there is this thing called juhannus. A few years ago, our former colleague Hetta described it like this: Well, Midsummer – or juhannus – as it is called in Finnish, is one of the most important public holidays in our calendar. It is celebrated, as you probably guessed, close to the dates of the Summer Solstice, when day is at its longest in the northern hemisphere. Finland being so far up north, the sun doesn’t set on juhannus at all. Considering that in the winter we get the never ending night, it’s no surprise we celebrate the sun not setting. So what do Finns do to celebrate juhannus? I already told you we flock to our summer cottages, but what then? We decorate the cottage with birch branches to celebrate the summer, we stock up on new potatoes which are just now in season and strawberries as well. We fire up the barbecue and eat grilled sausages to our hearts content. We burn bonfires that rival with the unsetting sun. And we get drunk. If that isn't vivid enough, this video may help: [protected-iframe id="f18649f0b62adf8eb1ec638fa5066050-10874323-9129869" info="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fsuomifinland100%2Fvideos%2F1278272918868972%2F&show_text=0&width=560" width="560" height="315" frameborder="0" style="border: none; overflow: hidden;" scrolling="no"] And because the celebration is just so... celebratory, it's easy to lose your phone. So here are a few ways to prepare yourself for a party that lasts all night. 1. Don't use 5683 as your passcode. That spells love and it's also one of the first passcodes anyone trying to crack into your phone will try. So use something much more creative -- and use a 6-digit code if you can on your iPhone. You can also encrypt your Android. 2. Write down your IMEI number. If you lose your phone, you're going to need this so make sure you have it written down somewhere safe. 3. Back your content up. This makes your life a lot easier if your party goes too well and it's pretty simple on any iOS device. Just make sure you're using a strong, unique password for your iCloud account. Unfortunately on an Android phone, you'll have to use a third-party app. 4. Maybe just leave it home. Enjoy being with your friends and assume that they'll get the pictures you need to refresh your memory. And while you're out you can give your phone a quick internal "clean" with our free Boost app. [Image by Janne Hellsten | Flickr]
Little changes can make a difference. For instance, Twitter's decision to switch a star for a heart as its "Favorite" button increased use of the button by as much as 27.82 percent. And it's clear that despite Wall St. demanding that site grow faster and be easier for new users to grasp to have some hope of keeping up with competitors like Facebook and Snapchat, the site is still sweating the small stuff. Here are the four changes to the service announced this week: Replies: When replying to a Tweet, @names will no longer count toward the 140-character count. This will make having conversations on Twitter easier and more straightforward, no more penny-pinching your words to ensure they reach the whole group. Media attachments: When you add attachments like photos, GIFs, videos, polls, or Quote Tweets, that media will no longer count as characters within your Tweet. More room for words! Retweet and Quote Tweet yourself: We’ll be enabling the Retweet button on your own Tweets, so you can easily Retweet or Quote Tweet yourself when you want to share a new reflection or feel like a really good one went unnoticed. Goodbye, .@: These changes will help simplify the rules around Tweets that start with a username. New Tweets that begin with a username will reach all your followers. (That means you’ll no longer have to use the ”.@” convention, which people currently use to broadcast Tweets broadly.) If you want a reply to be seen by all your followers, you will be able to Retweet it to signal that you intend for it to be viewed more broadly. These tweaks are in line with Twitter's tradition of paying attention to how people use the site and make it easier for them to do what early adopters are already doing. That's how we got hashtags, retweet buttons and @ replies. Now you'll be able to tweet a bit longer messages, something people do now with screenshots of text, and have more public conversations, something people do now by putting a "." before someone's @username so their whole feed sees the conversation not just people who happen to follow you and the user you're conversing with. Cool. These are useful little nudges that will keep people who already love the site engaged -- even though they may have some ugly unforeseen consequences. But will they transform Twitter and spark a new wave of growth? Not likely. What would without alienating the hundreds of millions of loyal users? Tough question and we'd like to know what you think.
