Trioplan 100 f2.8 II – How the Soap-Bubble-Bokeh Is Created

We would like to take this opportunity to give you a little help getting started with your Trioplan 100. The Trioplan 100 is one of the most famous lenses worldwide for its bokeh effect! Which situations allow you to achieve these photographic blurring effects? You will need to consider a few things while both setting up the subject of your photo and photographing.

Soap-Bubble-Bokeh

To achieve the perfect soap-bubble-bokeh, it is important to position the subject at close range while keeping enough distance to create a high-contrast background.

The particularly sharp-edged, famous soap-bubble-bokeh is only produced at a maximum aperture. You should therefore use f2.8 for the strongest bokeh or f4.0 for a weaker Bokeh effect. The focused main subject of your photo should be approximately 1m to 5m (3.3ft to 16.5ft) away. The distance between the subject and background should be at least 5m to 10m (16.5ft to 33ft).

The closer the focus point to the camera, the greater the bubbles in the background. The stronger the background contrast, the more bubbles appear. Ideally, you should opt for a busy background with strong backlighting  such as light-filled trees, lights on a skyline at night, or fairy lights.

Tip

The Trioplan 100 is the perfect lens for use with an extension tube. The much shorter minimum focus distance enlarges the soap-bubbles in the background several times over. In addition, the lens shows close-range subjects in an extremely high and fine resolution.

Cover Motif Checklist
