Creative foregrounds

Canon lenses are engineered for optimum performance, but there may be occasions where you want to try a more distorted view. By placing objects close to the front of the lens, you can easily achieve a bold new look. Here are three quick and simple techniques to try out.

Positioning the lens very close to an object and selectively focusing on a subject beyond it allows you to frame your shot with an exaggerated foreground blur.

Try getting low to the ground to shoot through grass or flowers, or, as in this example, hold a string of LED lights a short distance from the front element of the lens. Choose a longer lens or zoom in for this technique, as it will appear to compress the scene and bring the foreground blur and the sharp subject closer together in your picture. Set a large aperture to produce larger, more rounded out-of-focus highlights.

This simple technique involves little more than holding a glass prism in front of the lens and changing its angle and position until you find an effect you like. These effects range from reflections to rainbows, curves to creative distortions; it all depends where you hold the prism in front of the lens and how you twist and rotate it.

Prisms are relatively cheap to buy online – look for one that’s around 15cm long, as this should allow you to hold it without your fingers appearing in the shot. Focus on the subject of the picture before you bring the prism into view, and set a large aperture to let plenty of light into the lens. Don’t let the prism touch the front of the lens – you may find it easier to fit the camera to a tripod so that you have more control over how the prism is positioned.
