Wanna make light blurs appears as rabbit ? Cool, right? Then read this!
Bokeh comes from the Japanese word boke (ボケ), which means “blur” or “haze”, or boke-aji, the “blur quality.” Bokeh is pronounced BOH-Kə or BOH-kay.
When we shoot a shallow depth-of-field (DOF) image that has high contrast in the background, especially bright lights – for example sun through trees or foliage, and say traffic lights viewed at distance at night – those textures are not shown as sharp objects in the camera on shallow DOF.
Instead the less sharp lights turn to round orbs which overlap because of the roundness of the overlapping diaphragm blades in the lens, and this effect is called “Bokeh”. Depending on the aperture setting and type of lens, occasionally the corners or overlaps of these blades is visible in the photo’s bokeh. Bokeh becomes more prominent with night time shots.
This, then means that if the lens diaphragm blades are round they create a round orb in your viewfinder and on the image taken. You can then change the shape of the bokeh in your photos by adding another shape – basically any shape you like.
To do this you can either make your own shapes and cut them out of black paper or plastic or alternatively you can buy a bokeh kit – which has a piece of plastic that you attach to the end of your lens (I used elastic bands) and then you can attach the shape of your choice to the end of that lens via the slot provided – in this particular case I chose a rabbit.
The pack I bought contained 72 different shapes – the shapes included a diverse range from hearts, leaves, and smiles to witches, spanners and snowflakes! I elected as a precaution to also tape the rabbit in place as it was a rather windy evening!
You can use an analogue or digital camera to create this effect, it matters not. In the gallery you can see the effect of Bokeh at night with and without the rabbit shape. The Lomography X Zenit Petzval Art Lens was perfect to use to create this effect.
