What does a Parabolic Softbox Do?

Deep softboxes, sometimes called Parabolic Softboxes, while maybe not seeming very different from standard or more shallow softboxes, can have an impact on your lighting. If you're trying to choose between a parabolic vs a standard softbox for which one would be best for you, then we're here to help.

What is a Parabolic Softbox?

Parabolic softboxes are characterised by their deeper design and long reflector style compared to most standard softbox designs. Especially compared with other more flared softbox styles, Parabolic softboxes can often have a more closed end, which makes them look more conical. 

What are Parabolic Softboxes used for?

Generally, parabolic or deep softboxes are used for things like portraits. Due to their round shape, they can leave round catchlights in the eyes of models, and will create an even spread of light, though, it can depend on the style of portrait you're aiming for as to whether a parabolic softbox is for you.

While oftentimes, if someone wants to create a tighter, more focused beam of light, the best option is to use barebulb flash or something like a metal reflector, lots of people like having the option to modify this light and add or remove diffusion to soften the effect. 

Parabolic softboxes aren't for everybody, but they can be very versatile in the right situation. 

Standard Softbox vs Deeper Softbox

Due to the design of a deeper (parabolic) style softbox, the difference lies in the output of light and the spread it creates. Deeper softboxes with a conical design will have a smaller light surface at the face of the softbox, and will therefore create a smaller spread of light, therefore focusing more of the light in one area and creating more contrast. A larger standard softbox with a wider face will spread the light wider and more evenly, therefore reducing shadows and creating a super soft effect. Shorter softboxes (Especially undiffused) can leave a hotspot effect in comparison, however will often be more efficient.

Some Parabolic softboxes are also designed to mount the light facing into the softbox rather than facing outwards, to create indirect lighting, and giving you the option to move it closer into the softbox or further out to create a softer, wider spread effect.

So which one should I get?

For softer light and non-portrait work, go for a large standard style softbox. A parabolic softbox is great for portraits and will add more contrast, and can be versatile when paired with inner diffusers and grids. 

For a more intensely focused beam of light, look for a long metal reflector or a snoot instead.
