An octabox is a type of softbox with eight sides and a rounded shape, while a standard softbox is a rectangular-shaped light modifier with four sides.
The primary difference between an octabox and a standard softbox is their shape and size. Octaboxes have a rounded shape that helps to create a more rounded, softer light source, while standard softboxes are typically more rectangular in shape and provide a harder light.
Another difference between the two is the number of sides they have. An octabox has eight sides, while a standard softbox typically has four. This difference in sides contributes to the difference in light quality between the two, with an octabox providing a more rounded light and a standard softbox providing a more directional light.
The number of sides on a softbox also affects the way that light is spread from the source. Octaboxes have a more even distribution of light because of their rounded shape and multiple sides, making them ideal for portrait photography. Standard softboxes, on the other hand, tend to produce a more focused, directional light, making them better suited for product photography or other applications where a hard light is desired.
In terms of size, octaboxes tend to be larger than standard softboxes, which allows for a greater spread of light. This makes them ideal for larger subjects or groups, while standard softboxes are better suited for smaller subjects or individual portraits.
Another important consideration when choosing between an octabox and a standard softbox is the type of lighting equipment being used. Octaboxes are typically designed to be used with larger, studio-style light sources, while standard softboxes can be used with smaller, portable lights.
In conclusion, the choice between an octabox and a standard softbox ultimately depends on the photographer's specific needs and the type of photography being performed. Octaboxes provide a more rounded, even light and are better suited for portrait photography, while standard softboxes provide a more focused, directional light and are better suited for product photography or other applications where a hard light is desired.
