Have you ever seen photos which looks like a miniature model, yet when you look closely you realise the river, the cars and the people are all real? You then find out that it was all because of some photography technique.
There are actually a few ways to achieve such effect, the most straight forward, direct way is to use a tilt-shift lens. It is rather expensive, for example the Canon TS-E 24mm f3.5L will cost you over HKD14,000 (USD1,790). There are also some built-in filters in newer point-and-shoot cameras (or smartphone apps) which mimics similar results . Another method which I like is by post processing in Photoshop.
The above photo was taken in Prague using my 5D Mark 2 and a Canon 24-70mm f4L lens. It was inspired by a postcard I saw when walking along Charles’ Bridge, and realise that this scene has been taken thousands of times, in colour or black & white. I wanted to give it a different look and not just taking another “postcard moment”. I used a plug-in called “Bokeh 2” by Alien Skin, which is a fantastic piece of software to add planar or circular Bokeh in Photoshop. On the other hand you can use blur filters with the gradient tool to get a similar effect.
To have the best result, a photo taken from a high vantage point is key. Just imagine you looking down at a model sized town and you will understand what I mean. Give it a try and you may discover new ways to see things!
