It’s been some time since we first looked at photo-sharing app Tadaa, which we noted at the time builds on Instagram’s template with more Twitter-like features for social photographers.

Instagram may have gone on to dominate the filter/sharing/social photo-app realm, and it even has that billion-dollar Facebook acquisition to boast, but with around 3 million downloads to date, Tadaa has also carved a sizable niche for itself in what has become a pretty saturated space, with arguably a more sophisticated offering than some of its peers.

Tadaa boldly claims this “patent-pending” edge detection feature to be a “world first” for such a mobile app, so we thought we’d take a look to see how good it really is.

Oh, and edge detection, incidentally, is the technical term for identifying specific points and objects in a digital image. In the case of Tadaa, it promises to separate the main subject (e.g. a person) from the background surroundings to create distinct effects and a sense of depth

Tadaa & edge-detection

You can take a snap on the spot, or reel in images from your camera roll. Click the little edge-detection button on the top left next to the crop icon, and you’re good to go.

You trace an area around the main ‘focus’ region, and Tadaa snaps around the edges of the area it thinks you want to focus on.

Next, you can adjust the background blur to make the foreground standout, while you can also change elements such as brightness, contrast and saturation, and other finishing touches to the background.

Then, you can save it to your camera roll or share it across the social sphere.

Certainly, the outcome is quite impressive and it does create a genuine depth of field similar to what you’d get with a DSLR. But is this actually all that revolutionary? Other apps profess to offer such features, including AfterFocus for iOS and Android, not to mention Big Lens (iOS only).

I thought I’d put Tadaa up against Big Lens to see what the actual difference was, and here’s the result with Tadaa on the left:

If truth be told, I didn’t think there was too much in it, both produced roughly the same output, though maybe someone with a better eye for this kind of thing would disagree.

At any rate, it’s a nice addition for Tadaa and one that will likely prove popular with its 3 million or so users. Plus, for the time-being, Tadaa remains totally free, though there is a suggestion it may eventually cost to use the edge detection feature.

“We can’t wait to see how our users react to this new feature,” says Nikolas Schoppmeier, Tadaa’s Co-Founder & CEO. “There is no other app out there with a feature as sophisticated as this so we’re very excited. This feature is just one more reason to leave your expensive SLR at home the next time you want to take great photos. We’re equipping our users with a set of tools that only professional photographers have access to and we’re striving to make them as accessible as possible.”

Tadaa version 4.7 is available to download now.
