A team of researchers from MIT (Tianfan Xue, Michael Rubinstein, Ce Liu and William T. Freeman) are teaming up with Google with to present a new algorithm that is able to extract photographic inconveniences such as glares and reflections from photographs. The algorithm can then reproduce the image free of any reflections, in addition to being able to create an additional image of the reflection itself. This kind of problem solving would be especially useful when shooting behind glass or a fence, for example. [Read more…]
Windows have been ruining photos ever since the first time a photographer tried shooting through one.
Unless you bring along dedicated contraptions or start messing around with cloths and funny angles, shooting through the glass will likely lead to an annoying reflection that will make you want to smash it to pieces. (If you’re actually trying to get a reflection then scratch everything I said; windows are awesome).
This problem might soon come to an end, though; as researchers say they’ve developed an algorithm that can automatically remove reflections from digital photos. The algorithm can’t remove all types of reflections, but it does an impressive job with the ones it can remove.
Last year I made an article about getting good gradient reflections on surfaces, but after a while of using this that I’ve come to realize that I actually get slightly better (and easier) results with a different technique.
You can consider this as he second part of the How To Get Gradient Reflection On Surfaces tutorial.
Getting gradual reflection on a shiny surface is not trivial. It is not hard, but you have to know how it is done (which you will once you’ve read this post :). This is one of my favorite techniques when shooting products with a granite tile, and it gets that gradient reflection on a reflective surface every time.
I got a couple of messages on Flickr a while back asking me how to get a gradient effect on an iphone shot I did before. So here is a step by step lighting tutorial on how to achieve this kind of lighting and where you can use it.
