This head-turning effect may look like it was created entirely in post-production, but it’s less complicated than that. To achieve it, you’ll need to get hold of a glass prism, which can easily be found in all shapes and sizes and to suit all budgets on sites like eBay and Amazon. A 4-inch glass prism can be sourced from eBay for less than £10/$10 and is a great way to get started. If you like the prism technique, you may want to upgrade to a Fractal Filters Classic 3-pack, which is more versatile but comes with a premium at $119.
Bear in mind that the prism needs to be long enough to cover the whole front element of your lens (for most 35mm, 50mm and 85mm prime lenses, the 4-inch version will be fine). Requiring hand-holding, the prism needs to be long enough to avoid your fingers appearing in the shot.
