How to Bokeh

Bokeh ay, I’ve been meaning to try it out for over a year, and now I’ve finally cracked it. It was much easier and much more fun than i first imagined. I’m not at all skilled with manual photography, and this was relatively easy for me.

Bokeh is a work used to describe two things:

1. Photographing something in crisp focus with the background blurred (bit boring)

2. The exciting kind, where you photograph lights using a lens cut into a shape, i.e. hearts, triangles, lightening bolts, arrows and each separate light becomes that shape.

The type of Bokeh I’ve experimented with is the second kind, and I make this the focus of my images. Most bokeh has the focus on an object in the foreground, but I just love the light being in different shapes, and got a bit carried away with this. I’ll call it ‘level 1 bokeh’!

So I made a tutorial of how you make your own Bokeh lens:

Here’s what you need: your camera, masking tape, a scalpel, scissors, thin cardboard (half a cereal box is perfect) and a pencil

1. Draw around the lens of your camera

2. Cut the circle out, leaving 1/2 an inch of extra circumference

3. Then use the cardboard to cut a seperate  2-inch wide strip of cardboard which will fit around the side of your lens, leaving 1/2 an inch spare of length at the end. Tape this to the lens using the masking tape, then slide off

4. Pick up the circle, and cut into that 1/2 an inch of extra circumference, creating a bit of a frill/flap, all the way around, making cuts every half a centimeter or so

5. Bend those frills/flaps down

6. Use a scalpol to cut out a shape of some sort in the centre of the circle (ideally you’d measure where the centre is). My favorite is an arrow

7. Now you attach the strip and the circle together to make your Bokeh lens. Use one bit of tape to start off with, then keep tucking the flaps in and sticking

8. Work your way around the circle, until it’s all tucked in and stuck down with a few pieces of tape

9. Nearly there

10. On the inside, stick some tape there too – to make it more of a rigid structure

11. Finish off the lens by making taping over all the gaps on the outer side

12. Done! Go and photograph some lights


And here are the technical things:

The size of the shaped hole depends on two things: the aperture of your lens and the focal length you’re using.

Try using these calculations, which I copied from DIY

Take the focal length that you wish to use (e.g. 100mm)

Divide this by the aperture value that is smallest on your lens (e.g. f/2)

Equals the largest diameter of the cut out shape (shape should be smaller than this) (50mm)


50mm f/2 – shape must be under 25mm

75mm f/2 – shape must be under 37.5mm

100mm f/2 – shape must be under 50mm

50mm f/2.8 – shape must be under 17.5mm

50mm f/3.5 – must be under 14.2mm


Other important things:

  1. Make sure the shape you create is in the centre of the circle
  2. The lights you shoot need to be really bright (traffic lights, car lights, city lights, amusements, street lights, carnivals, bright bulbs)
  3. When you’re focusing, make sure the lights are out of focus, otherwise the shape won’t come through
  4. If you’re shooting an object infront of the bokeh lights, focus on that object with distant lights out of focus behind (a shallow depth of field)
  5. If the image is coming out too dark, increase the time the aperture is open. This means a longer exposure, letting more light in, and the image will be brighter

Here’s some more of the images I created:

Simple way to create text artwork

I just found a brilliant tutorial over at the Wicked & Weird blog (A good’n for a variety of creative inspiration) The blog post was a re-post, originally taken from A Beautiful Mess, and the blog post has detailed steps and lots of images to help you with this DIY project.

This is what you’ll make:

And this is how you’ll do it:

  1. Find a crap old painting
  2. Use sticky letter stickers to spell something out on-top of the painting
  3. Spray/Paint it all white
  4. Then peel the letters off.

Thomas Forsyth’s drawing tops

Thomas Forsyth is a genius AND a nice man. He creates these:

A spinning-top, that uses a pen as the spindle, represents many of the core ideas behind my current work. It is recognisable, un-intimidating, and invites people to interact with objects that can lead to unpredictable results, or an emergent property. Simply through indulging in the enjoyable process of spinning the top a bi-product is created. Where the pen marks the surface, a beautiful map of the experience and events that have occurred is produced. I am able to draw, but I am not particularly talented at it and yet found that, through the interaction with these objects, I have created drawings that I am more proud of than any I have done before.

Have a look at his video here which gives instruction on how to make your own drawing top using very simple materials. I want to use drawing tops in my art workshops for Light Box: The Happiness Project. Here’s my trial using a DIY drawing top:
