The importance of using light blockers in photography

Photography is an art form that relies heavily on capturing and manipulating light to create stunning images. Light is the essence of photography, but at times, too much or unwanted light can be detrimental to the final result. This is where light blockers come into play, serving as indispensable tools for photographers looking to control and enhance the quality of their shots. In my last post, I mentioned diffusion, but you can also block light to create beautiful portraits.

In the above image, we were using constant studio lights. But there was a shaft of super bright light in the back right-hand corner. Sure, I could edit it out in Photoshop, but instead, I grabbed a V-flat and covered the light coming from the window.

Controlling exposure and highlights

Light blockers, also known as flags or gobos (go-betweens), are essential for photographers seeking to control exposure and manage highlights. When shooting in challenging lighting conditions such as harsh sunlight or reflective surfaces, these blockers help prevent overexposure by selectively blocking as opposed to diffusing light.

This ensures that the details in both shadows and highlights are preserved, resulting in a more balanced and visually appealing image. A simple and cost-effective light blocker is the black fabric provided in a 5-in1 reflector. Alternatively, a V-flat painted black on one side works well too.

Creating dramatic shadows and depth:

Photography is not just about capturing what is visible but also about creating a mood and telling a story. Light blockers play a crucial role in sculpting light and shadow, allowing photographers to add depth and drama to their compositions. By strategically placing blockers to cast shadows or control the direction of light, photographers can evoke emotions and convey a narrative within their images.

Enhancing composition and framing

Light blockers are versatile tools that aid in composing and framing shots effectively. They can be used to eliminate unwanted elements in the frame. This ensures that the viewer’s attention is focused on the subject.

Additionally, blockers can be employed to frame subjects, adding visual interest and guiding the viewer’s gaze toward specific areas of the photograph. This helps in creating a more engaging and aesthetically pleasing composition.

It can also block out unwanted elements or light where it is not required. Even in a studio environment, light from windows and other sources can encroach onto your background, adding unwanted elements.

Achieving creative effects

Experimentation is at the heart of photography, and light blockers provide photographers with a means to achieve creative effects. By manipulating light sources through blockers, photographers can produce unique and artistic results.

Whether it’s creating patterns of light and shadow or adding a touch of mystery to a portrait. The use of light blockers opens up a realm of possibilities for photographers to explore and express their creativity.

Adapting to various environments

Photographers often find themselves in diverse shooting environments, each presenting its own set of lighting challenges. Light blockers are invaluable in such situations, allowing photographers to adapt quickly and efficiently. From outdoor shoots under the glaring sun to indoor setups with artificial lighting, the ability to control and modify light using blockers ensures consistent and high-quality results across different settings.

Much better without unwanted light


In the world of photography where light is both the medium and the message, using light blockers is a fundamental skill. These unassuming tools empower photographers to control exposure, shape compositions, and infuse their work with a touch of creativity.

Aspiring photographers and seasoned professionals alike should consider light blockers. They work great not just as accessories but as indispensable instruments that unlock the full potential of their craft. Embrace the magic of light manipulation and watch your photography reach new heights.
