What is a Photography Prism? And How Does a Glass Prism Work?
A glass prism is in essence, a light refractor!
White light is made up of the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet – and prisms quite literally show these true colors. You may have seen it on Pink Floyd’s iconic Dark Side of the Moon album cover – simply put, white light goes into prism, colors come out.
So, what does this mean in a photography context?
The refracting (aka bending of light) prisms offer will create unique looks for your photos – letting you project rainbows, reflect your frames, multiply your subjects, blur out distracting background elements, and more! The best part? It’s all in-camera, no editing required.
The Best Photography Glass Prisms to Buy
Photography prisms and light refraction tools can be found in all shapes and sizes lately – let’s check them out.
Triangular Photography Prisms
Triangular prisms are the most common of them all. Depending on the size of your lens, the type of look you’re after, and what’s comfortable for you to hold, they’re available in their traditional elongated form, or shorter models at less than half the size.
If you’re looking to get more experimental with your shots, you can even get a full set of different shaped glass prisms, from lens balls to cubes.
When looking for a high quality prism, you want it to be made of glass, and free of bubbles for the cleanest possible images.

How to Use a Glass Prism for Photography
Get the most out of your triangular prism with these tips and tricks! If you learn better by watching, photographer Dan Bullman runs through prism photography tips in this tutorial.
- To start, simply hold your prism in front of your lens
- Find a source of light to add color to your photos (sunlight, neon, anything!)
- Don’t fully cover the lens with your prism
- Use your viewfinder to preview images as you go
- Experiment with different angles by spinning the prism around
- Adjust aperture to be as low as possible (f-stop of around 2 or lower works best)
- Set focus mode to manual, and use trial and error to achieve the exact effect you want!
Glass Prism Photography Effects & Ideas
Now that we know what prisms are, the different types, and how to use them – let’s get into the best part: ideas and inspo for your own prism photos!
Refract Light for a Colorful Rainbow Effect
Since a prism literally takes white light and refracts it – projecting all the individual hues – one of the most popular ways to use a prism is to project a rainbow! Whether it’s on your portrait subject’s face, or against a still life subject, add some color and energy to your photos with this technique.

Create Reflections & Leading Lines
With a triangular glass prism, you can bend minds and reflect your image in-camera simply by angling the prism a certain way in front of the camera. For this technique to work, you want to have the corner of the prism directly facing your lens, to capture a 45º angle tilting in on both sides of the corner.
A unique, lesser-seen technique for prisms in photography is using these reflections to create leading lines! With prisms’ ability to reflect, use this to your advantage to draw attention to your subject. You can even work in some symmetry, too.

Balance Overexposed Light Source
A prism can also be used to block a source of overexposed lighting. If you’re shooting midday and have harsh lighting directly on your subject from the background, you can use the prism to block or diffuse the light source, balancing out the exposure.

Minimize Distracting Objects in Shot
Last but not least, an under-utilized prism technique is using it to minimize distracting elements in your frame. Whether you’re shooting in a tree-filled forest, or on a busy sidewalk, the prism can help blur your background for at least half your image – letting you still capture the essence of your setting, without it stealing the show from your subject.
