There are a number of light direction and diffusion tools available to be chosen from. Used in studio photography, they soften the ‘hard’ light caused due to the subject directly being exposed to the source of light.  

An octa softbox and a square softbox are the two most used types of light diffusion tools. The differences in the details created by both the tools are minute but the difference separates a good photograph from a bad one. 

You may find that the octobox is also an eight-sided softbox. However, an octa softbox is used for video shoots as well, but more often than not a square or a rectangle softbox is used with flashes and for photography. 

Advantages of a Rectange Strip Softbox

Softboxes have a universality that many photographers love. A rectangle or a square softbox may not yield flattering and attractive lighting when used for portrait photography as opposed to its counterpart; however, they deliver great results with photos of inanimate objects, art, and products.

The lighting achieved with a four-sided softbox falls much quicker than an octabox. Apart from that, it helps you achieve a window-like effect if desired with your product or object. 

A Godox square softbox is usually equipped with a Bowen’s mount which could be used with products from other brands with the same mount, making it more versatile. 

Grids for Rectangular Softbox

A grid softbox helps you achieve a soft and flattering look, like without a grid, but in a more restricted manner. It is an effective tool if you want your subject close to the background but well lit.

Rectangle grid Softbox

The aspect ratio of a rectangle grid softbox creates a unique versatility. You can use it both, horizontally and vertically, depending on your needs. 

When used vertically, it creates a contrast between the background and the foreground. The rectangle grid allows you to cast the light accurately in the direction you wish. Depending on the size, it can be used to create an evenly lit half-body portrait if you use it for portrait photography.

If you use it horizontally, it could create good lighting for headshots in portrait photography. This helps create a gradient from highlights to shadow on the face of the subject. 

Square grid Softbox

While practicing off-camera flash photography, a square grid softbox is an essential add-on to your lighting kit. A square grid, when used with a softbox, diffuses a narrower beam of light. It enables you to control your lighting precisely and helps you create a picture like it is in your head. 

A Godox square softbox with a grid will give you more control over the lighting as opposed to other competitors. 

All being said, it comes down to a matter of personal choice and usability of your lighting equipment.
