Yongnuo Speedlight Kit – Twin Softbox Foldable Quickup:
Which is better soft box or umbrella?
We also use soft boxes for softening and increasing the size of a smaller light source.
And diffuse light sources not unlike umbrellas—with a few notables differences.
A soft box controls the shape and direction of light more than an umbrella and prevents more light-spill from occurring.
It’s a secret that portrait, product and commercial photographers have long known:
Also the value of using a soft box in their studio photography.
A soft box diffuses the light into a pleasing soft, even light.
When used, it reduces harsh shadows.
The closer the soft box is to the model or subject, the softer the light appears.
Emulating window light.
All the shape of a soft box can vary from rectangular to octagonal to square to a long strip of light.
A soft box comprises translucent cloth and attaches to a light source.
(A studio strobe or Speedlight) on a light stand.
Cloth, white or silver for the interior and black for the exterior.
Is wrapped around a wire-framed box covered over the front with a diffusion panel.
The black exterior prevents light from spilling out and reflecting in the studio.
Light emanating from the strobe or Speedlight is bounced around the fabric box and scattered in all directions inside the box.
All the sides of the box direct the light outward.
Light flooding out of the box is distributed from top to the bottom of the box.
Soft boxes come in a variety of sizes from small hand-held attachments to large wall-size modifiers.
Smaller soft boxes are more portable than their larger counterparts and are therefore great for on-location shoots.
But whether you haul out a large soft box or opt for a smaller, more portable one.
This area of coverage is about the same size.
(Assuming that the light modifiers are the same distance from your subject).
There is about a 1-1.5 stop falloff on the sides as the light wraps around your model.
The sweet spot for soft boxes is about six feet away from your model or subject.
But why have different sizes?
It’s all about the quality of light.
Large soft boxes cover a broad area with undefined shadows.
Medium-sized soft boxes provide harder shadows.
And small soft boxes throw off harder and well-defined shadows in the background.
Often a grid or egg crate is attached to the front of a soft box (with Velcro).
This accessory, which looks like a honeycomb.
Gives the photographer a little more control over the light with a narrower focus on the subject and less spillage on the background.
