Where to get a circular prism

These are actually for a chandelier and they are really cheap! This circular prism is the kind you will need.

Which lens should you use with a circular prism?

I’ve tried this with a 35mm, 50mm and 85mm lens and I like them all for different reasons. With the 35mm, you can hold the prism pretty close to the lens, and with a 50mm or 85mm, you’ll want to hold the prism a little farther back from the lens.

Look through the images on this post to see what lenses were used for each shot.

What lighting conditions are best for circular prism photography?

You can use a circular prism in any lighting condition, you will just get different results depending on the available light. Let me show you a few scenarios to explain what happens in different situations.

My absolute favorite way to use a circular prism is when the sun is low in the sky and utilizing backlighting. So just before sunset or after sunrise. The prism picks up all that golden sun and makes the most gorgeous, shiny ring around your subject. The next photo was taken with an 85mm at f4.0.circular chandelier prism - Creative photography

You can also use it with window light behind your subject and the prism will pick up the shape of whatever is in or outside the window because that is the brightest part of the scene. Or it might grab light pieces on your subject’s clothing or even pale faces. In the photos below, you’ll see that the prism picked up the hearts from my daughter’s pants & her pale hand, and the green trees from the window.circular prism ring of fire photography technique

And in the next photo, it picked up those Easter decals that are stuck to her window. Full disclosure: I took this image last weekend and it is January. Maybe it’s time to scrape those things off?? 35mm at 1.8black and whie image of little girl playing with a doll

And here, it picked up her face, which is creepy but cool at the same time. 35mm at 1.8 

Another way to use your circular prism is indoors without a light source behind your subject. In this case, it will pick up shapes from whatever bright things are around you. In the examples below, I used a 35mm at 2.0 and the prism picked up the light from windows behind me.

If you want to try an 85mm indoors without bright lights, it will most likely not give you that circular look, but it does do some interesting reflecting and sometimes you get rainbows. In this photo, I used an 85mm at f2.0.Little girl playing with dolls - circular prism and 85mm lens

Selecting the best aperture

I’ve noticed that your ideal aperture is different depending on the lighting. If your light source is super bright (like the sun), you’ll want a larger aperture. I think that around 4.0 is the sweet spot for me. Any smaller and the effect kind of takes over the entire photo. But when you’re inside and the light source isn’t as bright, you will want a smaller aperture closer to 2.0. So basically, the brighter the light source, the larger the aperture. But mess around with this and see what happens!

How to hold the circular prism correctly

This might be the most important part of this entire circular prism photography tutorial! If you try to just hold it with your fingers, your fingers will not be able to hide. This is especially true when using a wider lens like the 35mm. See the example below where I had to crop the image in (and also those two above) because my stupid fingers ruined it.Circular prism photography tutorial - how to hold the prism

So the solution is to get a string or something that will fit through the hole on the side. Since it was made for a chandelier, luckily the hole is already there. The only issue I’ve found is that my string breaks after a while since the prism is a little on the sharp side (which is why sometimes I have to use my fingers).

Once you have a string tied on, you just hold the string tight, right next to the prism so you have a good hold on it. If you hold the string farther back, the prism will spin and swing and could hit your lens. So don’t do that. Make sure to be really careful that the prism doesn’t touch your lens because you don’t want any scratches! I’d suggest either putting on your lens hood for extra space between your lens and the prism, or putting a filter over your lens. Scratching a filter is way better than scratching a lens!
