DIY Softbox for Better Video Lighting
Good lighting can completely transform the quality of your videos and photos. In this DIY softbox tutorial, I’ll show you how to create an affordable lighting solution that helps reduce harsh shadows and create softer, more professional-looking results.
Whether you’re filming YouTube videos, recording an online course, photographing your baking creations, or creating content for social media, having the right lighting can make a huge difference.
The best part? You don’t need expensive studio equipment to achieve better lighting.
Alright, let’s DIY!
The Lighting Problem I Wanted to Solve
When I first started making YouTube videos, I bought an inexpensive light online. At the time, I thought all I needed was a light that was bright enough to illuminate my subject.
As I gained more experience with filming, I realised that brightness alone wasn’t enough. No matter where I positioned the light, it produced harsh shadows that made my videos look less natural and less professional. I wanted softer, more even lighting that would make my baking videos look their best. (images 1 & 2)
I started looking into softboxes, but many of the options on the market were more expensive than I wanted to spend. Since I was trying to improve my filming setup on a budget, I decided to see if I could make my own instead.
That simple DIY project turned out to be one of the best improvements I made to my filming setup. I’ve been using this homemade softbox for years, and it continues to give me the soft, flattering light I was looking for—without the high price tag. (image 3 & 4)
What Is a Softbox and Why Is It Useful?
A softbox is a light modifier that diffuses the light from a lamp or bulb, spreading it over a larger surface. Instead of producing harsh, direct light, it creates a softer, more even light that wraps around your subject.
The biggest benefit of using a softbox is that it helps minimise harsh shadows, making your videos and photos look much more natural and professional. It’s especially useful if you film tutorials, take food photographs, create online courses, or produce content for social media.
The good news is that you don’t have to spend hundreds of pounds to enjoy these benefits. With a few inexpensive materials and a little DIY, you can build a softbox that works surprisingly well and gives your content a much more polished look.

Materials You’ll Need for this DIY Softbox project
The great thing about this DIY softbox is that it’s made from inexpensive, easy-to-find materials. You may even have some of these items at home already.
- Cardboard Box: A sturdy cardboard box forms the main body of the softbox. I recommend choosing a larger piece of cardboard rather than a smaller one. It’s much easier to trim a large piece down to size than to join several smaller pieces together, which can make the softbox less sturdy. When cutting the cardboard, always place a cutting mat underneath to protect your work surface. It’s also a good idea to wear a pair of cut-resistant gloves for extra protection and to help prevent accidental cuts while using a craft knife.
- Duck Tape: Use duct tape to assemble and reinforce the cardboard. It helps hold everything securely in place and makes the softbox more durable.
- Diffuser Material (What I Used): I used a white bin bag as the diffuser. It softens the light beautifully while allowing plenty of light to pass through, making it a simple and budget-friendly choice.
- Alternative Diffuser Material: If you don’t have a white bin bag, you can also use baking parchment paper or a piece of white fabric. These materials work in a similar way by diffusing the light and reducing harsh shadows.
- Clips: A few clips are useful for securing the diffuser to the front of the softbox. They also make it easy to remove or replace the diffuser whenever needed.
- Black Paper (Optional): I covered the outside of my cardboard box with black paper to give the softbox a cleaner, more finished look. This step is completely optional, but it makes the DIY softbox look neater and more professional.
- Glue Stick: It is used to attach the aluminium foil to the cardboard pieces. It provides enough adhesion to hold the foil securely while keeping the surface relatively smooth.
- Double-Sided Tape: It is used to stick the black paper onto the cardboard, creating a neat finish without visible tape marks.
How to Make a DIY Softbox
Step 1: Measure the Light
Before you start building your softbox, take some time to understand how your light works. Every light is different, so measuring it first will help you build a softbox that fits properly and allows the light to move freely.
- This is the light I’ve been using since the very first day I started filming my YouTube videos. Although it’s bright enough, it produces harsh shadows, which is why I decided to build a DIY softbox.
- Check how your light moves. My light can tilt up and down, so I needed to make sure the softbox wouldn’t restrict its movement.
- Measure how high the light can tilt. This tells you the maximum clearance needed inside the softbox.
- Measure the light again when it’s tilted to its lowest position. Comparing both measurements will help you determine the largest base your softbox can have while still allowing the light to move freely. For my light, the maximum tilt is about 10 cm, so I made the base of my softbox 20 × 20 cm. If I made it any larger, the light would hit the sides of the softbox and wouldn’t be able to tilt properly. Taking these measurements before you begin will save time and help you build a softbox that fits your light perfectly.
Step 2: Measure and Mark the Cardboard
Using a ruler and pencil, carefully mark out each piece of the softbox according to your measurements. Take your time with this step because accurate measurements will make the assembly process much easier later.
Using a craft knife and a cutting mat, carefully cut out all the cardboard pieces. Cut slowly and accurately to achieve clean, straight edges that will make assembly much easier.
- The base of my softbox is a 20 cm × 20 cm square. This measurement was based on the maximum movement of my light, which I worked out in Step 1.
- The four trapezoid-shaped pieces form the sides of the softbox. These pieces help create the angled shape that allows the light to spread more evenly.
- The front rim is the frame that holds the diffuser material in place.
- These four narrow strips are used to join and secure the corner pieces together, helping to strengthen the structure of the softbox.
If you would like to see the exact measurements and how I accurately cut out each cardboard piece, please watch the video tutorial above. I demonstrate the full process step by step so you can follow along more easily.
Step 3: Wrap the Cardboard
Wrapping the cardboard is to improve the performance and appearance of the softbox. The aluminium foil on the inside helps reflect the light, while the black paper on the outside gives the softbox a cleaner and more finished look.
- Apply glue evenly over the cardboard surface where the foil will be attached.
- Stick the aluminium foil onto the cardboard, making sure the shiny side is facing up to reflect the light.
- If you don’t have a large enough piece of foil, you can patch smaller pieces together. It doesn’t need to be covered with one single sheet of foil—the important thing is that the reflective area is covered.
- Trim off any excess foil using a pair of scissors.
- On the other side of the cardboard, apply double-sided tape to both the cardboard and the black paper to make sure it is securely attached.
- Use duck tape to wrap the wider side of the trapezoid pieces. Leave both sides and the top edge uncovered, as these areas will be joined together during assembly.
- Reinforce the lamp opening on the base with duct tape. Since this is the area that holds the light, it needs extra strength to prevent the cardboard from tearing.
- Use duct tape to wrap the corner pieces and joining strips. There is no need to add foil to these pieces because they do not reflect or direct the light.
Step 4: Assemble the Softbox
Now it’s time to assemble all the prepared pieces and bring the softbox structure together.
- Lay two trapezoid-shaped pieces flat on your work surface. Apply duck tape along the inside seam to join the two pieces together.
- Flip the pieces over and secure the outside seam with another strip of duck tape. Continue joining the remaining trapezoid pieces in the same way until all four sides are connected.
- To join the final two pieces together, fold all the connected pieces into the shape of the softbox and stand it upright. This makes it easier to align the edges and secure the final seam. Once the shape is formed, attach the base of the softbox using duck tape.
- To give the softbox a cleaner and more professional finish, cover the visible seams where the black paper joins together with duck tape. This not only improves the appearance but also adds extra strength to the structure.
Step 5: Attach the Front Rim
The front rim is an important addition to make the softbox easier to use and more durable in the long term.
Instead of attaching the diffuser directly onto the softbox opening, adding a separate rim allows you to easily remove and replace the diffuser whenever needed. It also makes it much easier to access the light bulb if you need to change it in the future.
- Attach the corner pieces to the inside of the softbox opening using duct tape. Make sure they are positioned evenly and securely, as these pieces will support the front rim.
- Secure the corner pieces from the outside as well using duct tape to add extra strength and stability.
- Connect the corner pieces with the joining strips. Trim the strips if needed to make sure there are no overlapping edges and that they fit neatly together.
- Attach the strips to the corner pieces using duct tape to create a strong and stable frame. Continue joining the remaining corner pieces and strips until the complete rim is formed.
Step 6: Test the Illumination
Your DIY softbox is now complete! The final step is to attach it to your light source and see the difference it makes.
- Attach the light source to the softbox, making sure it fits securely inside the opening.
- Attach your chosen diffuser to the front rim using clips. I used a white bin bag as my diffuser, but you can also use baking parchment paper or a piece of white fabric.
- For extra security, use duct tape to secure the light fitting to the softbox. This helps keep everything firmly in place while you’re filming or photographing.
- Switch on the light and see the difference. You should notice that the softbox produces a much softer, more even light, helping to reduce harsh shadows and create a more professional-looking image.
How Well Does this DIY Softbox Work?
I’ve been using this DIY softbox for years, and it has become an essential part of my filming setup. It’s a simple, inexpensive project that has made a huge difference to the quality of my videos.
Before and After: The Difference a Softbox Makes
The easiest way to see how effective a softbox is is to compare the lighting before and after using it.
- Before Using the Softbox: Without a softbox, the light is much harsher and more directional. This creates strong shadows, bright highlights, and uneven lighting across the subject. Details can appear washed out in some areas while other areas are left too dark.
- After Using the Softbox: Once the softbox is attached, the light becomes much softer and more evenly distributed. The diffuser spreads the light over a larger area, reducing harsh shadows and creating a more natural, balanced look. The subject is illuminated more evenly, making colours, textures, and details appear clearer and more flattering.
Although the light may appear slightly less intense, the overall quality of the lighting is greatly improved. That’s why softboxes are so popular for video production, portrait photography, and food photography—they create a softer, more professional-looking result without the harsh shadows of direct lighting.
Frequently Asked Questions
Yes. In fact, I recommend using an LED bulb because it produces very little heat compared to traditional incandescent or halogen bulbs. Since this DIY softbox is made from cardboard, using a cool-running LED bulb is a much safer option.
The best size depends on your light. Before building your softbox, measure your light and check how much it can tilt or move. Your softbox should be large enough to soften the light but not so large that it restricts the movement of your light.
As long as you use a cool-running LED bulb and make sure the light is securely attached, this DIY softbox is safe for normal use. However, because it is made from cardboard, never it with hot light bulbs such as incandescent or halogen bulbs, and never leave it unattended while switched on.
Absolutely! A softbox creates softer, more even lighting that helps reduce harsh shadows, making food look more natural and appealing. Whether you’re photographing cakes, bread, cookies, or other baked treats, a softbox can help produce brighter, more professional-looking images.
