DIY Soft Box

by Mark Weber, M.Photog.Cr, M.Artist, CPP

Are you in search of a portable and less expensive soft box to use while you save up enough money for the professional brand? I have created many of my own DIY soft boxes over the years and you can too. You can make them any size and they have multiple uses!  A DIY soft box can serve as a light diffuser/modifier, a reflector and the substitute black rip-stop fabric doubles as subtractive

I like to use this DIY soft box indoors and out. If you have a breezy environment, the 1” PVC tubing is more rigid than the ¾” tubing. You also need to decide if you would like one that is portable. You don’t need to glue the PVC since it sticks together pretty good unless you get into a windy

The nice thing about the white rip-stop material is that it’s extremely durable. It doesn’t rip easily and if you happen to poke a hole in it, the hole won’t get bigger. The fabric is lightweight and diffuses just enough of the light to make it soft, but not so much that you loose too much illumination.

So, what else can you use these panels for?

  • Shoot a strobe through them to serve as a large soft box.
  • Hold them over a subject’s head to diffuse the mid-afternoon sun.
  • Switch out the white fabric for black and use them for subtractive lighting.
  • Peel down a corner to let some of the light spill out on your background or subject depending on the look you’re after.
  • Hang the frame with black fabric on your wall to keep light from bouncing in your high-key area.
  • Use it as a gobo between you and your subject to prevent lens flare under certain circumstances.
  • Simulate north window light by combing 2 strobes and 2 soft boxes side-by-side. A 7’x8’ soft box can be very pretty.

You won’t have the light head contained in this setup, but that’s okay. Even though it’s not as efficient as a covered head, it still makes a wonderful modifier.  You can experiment with how far to position your strobe from the fabric to fit your taste. I tend to keep mine 3 or 4 feet back, sometimes more. I like to angle the strobe head slightly up from the floor and away from my subject.

There is a more professional (complex) way to build these panels.  Dean Collins first introduced these designs back in the 80’s. Here is a link to get Dean Collins Tinker Tube instructions – http://www.software-cinema.com/page/13/tinkertubes. My instructions are more simplified, but they fit my skill level and patience. While it’s not as fancy, you can build it in no time and be ready to use it quickly. Here’s what you need:

¾” PVC/40 Pipe
Available at any hardware store (you can also use 1” if you prefer. Just substitute all sizes
accordingly. If you plan to use them outside, I would recommend the 1 inch.)
5 – ’¾’ PVC/40 Pipe
L = 8’ (source for all straight pieces)
4 – ¾” Elbow 90 degree PVC/40 for corners
3 – ¾” Tee PVC/40 for connectors
1 – ¾” connector to connect 2 straight pieces

Fabric – To slip on the frame.
Rip-stop Nylon (white)

Elastic Straps – To connect the fabric to the frame. You’ll need to glue elastic to the each of the
4 corners of the rip-stop fabric at 45 degree angles about 7 inches from each corner.  This allows you to quickly attach or detach your fabric.
4 – Elastic Straps

Fabric Glue
Adhere the elastic with this glue. Only glue the ends of the elastic onto the fabric!  Any permanent
fabric glue will work. Look for a bottle similar to this  – http://www.allstitch.net/product/fabritac-permanent-adhesive-large-10-oz-bottle-3813.cfm?aid=FABTAC-8&sid=googlebase&gclid=CLqBzejr6LQCFSemPAodtxcAWg

PVC Cement – Use this to make your pipe connections permanent. I tend to leave the corners
unglued so I can break it down for easy storage or portability. I lay my pieces on top of one end of the rip-stop material and roll it up. The elastic straps can keep it all together.

Saw –I use a regular back saw with a miter box to cut the pipe.  Here’s a link that explains different options –http://www.hammerzone.com/archives/plumbing/technique/pvc/cutting/sawing_pipe.htm

    A 3D diagram would have worked better as well as perhaps a picture of the finished product

    Hi Mark some of us old timers were building these in the 80’s ( Dean Colins tinker toys!! ) Yes this a great way for econicimal large soft boxes I have 2 of them from the 80’s Hank Morris Photography !!

    I have been using similar diffusion panels for years. They work wonderfully and I carry two of them in a bag on location all the time with various fabric to diffuse, block or reflect light as needed. I often use them to block light coming into a area of a room I’m photographing if its creating a hot spot in the images.
    I keep a supply of fittings and pipe in my studio if I need to build another one on short notice.

    They are extremely affordable, versatile and the ability to build them any size is invaluable. Just keep in mind that the larger ones can get hard to manage outdoors because of wind. Use a larger diameter pipe if you know you will use them outdoors more than indoors. Having a removable leg on one end allows you to have an assistant hold it over someone easily as the subject is sitting on the ground and the panel serves as a light diffuser with the white material or as a light block with the black material.
    You can also bounce outdoor sunlight into a shady area where your subject is from a medium lightweight plexiglass mirror. That’s another blog tho! LOL.
