Combining the bokeh effect with fireworks and the decorative lights commonly found during Diwali, Aditya Nair explores a new way of shooting festivities.

My Assignment

  • Description
    This was an attempt to shoot a millennia old festival in a new way.
  • Duration
    Creating this entire series took about 4 days. But, I still shoot images whenever I get the chance.
  • Notes
    When you see light sources, always think of what they would look like if you shot them as bokeh.

Bokeh has always intrigued me. At their most basic, they are spheres of light. It is the simplest representation of beauty in photography. In this series, what has fascinated me most has to be the different interpretations people give me for the same image. Where I see arrows, my aunt sees an “Om” and my parents, both doctors, see DNA structures.

My Perspective
While I would have loved to have been able to give an immensely philosophical reason for creating this series the honest, brutal truth is that the idea was created out of pure boredom. I was passing my time shooting fireworks from my window and the lights that hung on the tree at home during Diwali. The dilemma that arose was figuring a way to shoot the festival in a unique manner.

The Process
Shooting the images is easy enough. It was a matter setting my camera on manual focus and blurring out the light source. Due to the random nature of the bokeh patterns I could really experiment with the composition and almost none of the images were badly composed. After the first few pictures, I found that it was better to shoot a variety of images in terms of bokeh sizes and colours. This gave me the freedom to experiment with various combinations later on, when I was processing the images in Photoshop. The series is made up of two sets of images—those that were created in-camera and ones that were created in post-production.
With the in-camera images, I felt it better to keep a little bit of the background visible so that a blurred, hazy structure of the tree could be seen giving it an unnatural yet very cool and even spooky appearance. It also gave a structure to the image rather than just having floating colours.
The post-processed images, however, were shot using a fast shutterspeed to get a pure black background, making it easier to combine images. Also, with these images a structure came from the pattern they created. The best Blending mode (in Photoshop) for these images turned out to be Screen. However, other Blending modes can also yield unique results.
Noise was another tool that I found to be useful with this series. I chose to add the noise in post-production as it allowed me to introduce noise only in the bokeh areas. This gave them a sandy texture, while the black areas had minimal noise.
Since the colour of the light tends to get limited to the lights that you can find around you, the Hue/Saturation adjustment with the Colorize function becomes invaluable to get access to more colours. In some images, I simply chose to desaturate one set of bokeh for emphasis.
Ultimately the lights and colours of Diwali combined with the equally fascinating effects of bokeh are the basic elements of this series; what a friend described as “dude trippy stuff man”, his best rendition of a 1970’s hippie.
Creating these images is limited only to how much you are willing experiment with your pictures.

My Equipment: For this series, I used a Canon EOS 500D along with a Canon EF 50mm f/1.8. However, these images can be shot from any camera that gives you the ability to manually focus.

Nature of Bokeh

  • The size and nature of bokeh depends mainly on the focus, or rather the lack of it and the distance between you and the light source.
  • The more out of focus the image is, the larger the bokeh circles appear. This also results in more diffused edges and the intensity of the bokeh.
  • The closer you are to your light source, the larger the bokeh appears. If you want large bokeh circles which have sharp edges, shoot from close to the object with the image only slightly blurred.
