Double Liner

The Double Liner

The Double Liner Filter by SZ Filters creates two distinct parallel streaks of light across your frame. It adds a bold, symmetrical distortion that feels both graphic and cinematic — perfect for creative portraits, fashion, and experimental photography.

As you rotate the filter, the angle of the lines shifts, allowing you to shape the direction and energy of your composition. You can align them horizontally, vertically, or diagonally, depending on the visual rhythm you want.

Built with precision and creativity in mind, the Double Liner delivers structured in-camera effects without the need for post-processing. It’s a favorite among artists looking to blend control with bold optical impact.

Key Features:

• Projects two clean, parallel light streaks

• Lets you rotate the effect to change direction and flow

• Ideal for portraits, editorial shoots, and creative visuals

• Produces all effects in-camera, with no digital editing

• Handcrafted with precision by SZ Filters

Draw symmetry. Bend light. Redefine your frame.

You can combine it with all our available flat Filters such as the Mystic Dream or the Rainbow Starlight. Try it with our Filter Magnet Pro system for even easier use!

*All our filters are in 77mm size, and the reason is that after researching and using filters in various lens sizes, we found it to be the ideal size for use with any existing diameter using our Adapter Rings  and Filter Magnet Pro. We’re not interested in selling you a different filter for every lens you have; our focus is on enabling you to create incredible images with simplicity, speed, and creativity.
