This means that every stroke you make on the image will be interpreted as it is, as if you are drawing a line on the area, Tadaa SLR will not interfere with it. You can turn off the automatic edge detection and go ‘ manual‘. Sometimes the border is just too complicated Tadaa SLR just cannot detect the edges correctly no matter how much zoom/mask/erase you do. If you are familiar with Photoshop’s Magic Lasso tool, Tadaa SLR masking would be a familiar ground. Tadaa SLR will calculate the masked area and will detect, most of the time correctly, the border between the foreground and the background, and will automagically ‘snap’ the selection to only enclose the foreground object. That being said, the actual masking process is really as simple as brushing your finger over the object we want to stay sharp. “Tadaa simulates the physics of a true Tessar lens and renders physically correct bokeh (actually often more realistic then Photoshop’s DoF-Blur algorithm).” Which is the important factor where Tadaa seems to shine, at least according to what the co-founder and developer, Friedemann Wachsmuth, who said: For one, the edges where the foreground and the background, the border where the sharp begins to blur, needs to be calculated carefully otherwise the resulting simulation effect would be too obvious and the blur feels too ‘fake’. It sounds like a very simple technique, and in a way it is, but to simulate a real DoF effect takes more than just choosing the foreground over a background. not selected, is the part that will get blurred hence creating the DoF effect. The part of the image that is not masked, i.e. As you might’ve guessed from what I said just now, the way you create the DoF effect is by masking, in a way selecting, which parts of the image that we want to keep sharp. If you have used Tadaa Classic or Tadaa 3D in the past, or any app that has masking feature in their arsenal, you would not feel too alien with Tadaa SLR. This advance mathematical method is the core engine that also drives Tadaa SLR to do its DoF magic. Tadaa claimed that they employ a sophisticated ‘ Edge Detection Algorithm‘ to do their Bokeh rendition in the 2 previous apps. ![]() Recently they also created Tadaa 3D, a very interesting app which gives your photo a cool parallax view effect. They created one of the best alternative photo sharing app to Instagram called Tadaa, which has already a feature to add fake DoF included. The team behind Tadaa, a dev outfit from Germany, is not a stranger to the realm of photo app. You can use for example the Tilt-Shift feature (use the circular one) in apps like Snapseed, TiltShiftGen or even Instagram.įor the best quality that equals or at least closely comparable to what we get from the real DoF, we need to use apps that was especially created to ‘ fake it’. Basically any app that allows you to blur the background in some way or another can give you a rendition of a Bokeh effect, albeit a bad one. Many apps can actually create this effect, though quality varies. Of course this solution is not exactly the cheapest one, although a real 35mm Zoom Lens is not exactly cheap either □Īlternatively you can use one of the Photo Apps that allow you to create what I call a ‘ Pseudo DoF‘ or you can also call it a ‘ Fake Bokeh‘. Using this conversion lens, you might get a good DoF. Or you can employ one of those Tele or Macro conversion lenses you can widely get in the market. To achieve this your background should be in quite at a far distance from the foreground object. ![]() You can try use a technique where you go very close to your object, as close as your smartphone camera focus would allow, and hope that it will create enough Depth of Field to blur the background. This special feat is reasonably easy to achieve using manual camera, but with a smartphone camera this is almost impossible to get in a typical scene. Simply put, this is a photographic effect where a particular object (often located in the foreground, closer to the lens) appears to be sharp, while the rest of the background is out-of-focus or blur. One example of the thing that many of us would love to do with our mobile is to take a photo that has a Shallow Depth of Field (this will be abbreviated to DoF in this post) or more famously known as the Bokeh effect. That is until you want to do some specific things that the manual camera takes for granted, but almost impossible to do with the mobile phone due to its technical limitation. Our mobile phone camera is by far a sophisticated piece of engineering, and as far as ‘ painting with lights‘ concerns it is more than capable to produce excellent quality of images. Don’t get me wrong, as much as I love my iPhone, there are times when a manual camera is better suited for the type of photographic scene I want to create.
