DIY Light Box for Product Photography: Build One in 30 Minutes
Table of Contents
A light box (also called a lightbox, light tent or photo cube) is a small enclosure with translucent walls. You put the product inside, shine lights through the walls from outside, and the light arrives from every side, soft and even. It is the easiest way to get clean, shadow-free photos of small items, especially shiny ones like jewelry, watches, glasses and cosmetics, where a bare lamp produces glare.
You can buy a folding light box, but a cardboard one costs almost nothing, and the build below works just as well for the sizes most sellers photograph. It is one piece of the product photography at home setup.
What a light box is good for, and what it is not
Good for: small products up to roughly the size of a shoebox, jewelry, candles, skincare, small gifts, electronics accessories.
Not good for: clothing, large items, or anything where you want dramatic shadows and a lifestyle look. For those, use window light, see the lighting guide, or a flat-lay (clothing guide).
What you need
- A cardboard box large enough to hold the product with room around it. A box around 40 cm (16 in) on each side suits most small items.
- White tissue paper, parchment paper, a white t-shirt, or ripstop nylon for the diffusing walls. Avoid anything thick or patterned.
- White poster board, a roll of white paper, or a sheet of white foam board for the floor and back sweep.
- Tape and a craft knife or scissors.
- Two lamps with the same daylight-balanced LED bulbs (around 5000-6500K). Daylight from a window also works.
Build it
- Seal and prep the box. Tape the bottom flaps shut. Cut off the top flaps, or cut them away so the top is open.
- Cut windows. On the left wall, the right wall and the top, cut a large rectangular opening in each, leaving a border of about 3-5 cm (1-2 in) of cardboard so the frame stays rigid. Leave the front open, because that is where your phone goes.
- Cover the windows. Tape white tissue, parchment or fabric over each opening on the inside, pulled flat so it does not wrinkle. A smooth diffuser means smooth light.
- Add the sweep. Cut a sheet of white poster board a little wider than the inside of the box. Tape the top edge high on the back wall and let it curve down and forward along the floor. The curve is what makes the background look seamless, with no corner line behind the product.
- Add alternative backdrops. Keep sheets of black, gray or color poster board to swap in.
Light it
- Place one lamp on each side and one above, aimed at the diffusing windows, not at the product. If you only have two lamps, start with the two sides.
- Keep the lamps the same distance from the box so the light matches on both sides. Moving one lamp closer makes that side brighter, which you can use deliberately to give the product a little shape.
- Turn off the room lights so the box is the only source.
- If the top is dim, tape a white card across the front opening above your lens position, or point a lamp at the roof of the box.
Shoot it
- Put your phone on a tripod or a stack of books, level with the product or slightly above it.
- Use the 2x or telephoto lens if you have one and step back a little. This avoids lens distortion and keeps your phone out of the reflections. Use the macro mode on a newer phone only if the product is tiny.
- Turn off the flash. Tap the product to focus, lock exposure, and slide the brightness up until the white background reads clean white.
- Use the 3-second timer or a Bluetooth remote so pressing the shutter does not move the phone.
- Shoot more than one angle: straight on, three-quarter, close-up of the detail.
- Keep the product away from the walls. If it touches the diffuser, you will see the shadow of the tissue.
Fix the usual problems
| Problem | Fix |
|---|---|
| Visible creases or pattern on the background | Re-tape the paper smooth, or use a larger, smoother sheet |
| Dark corners in the photo | Move lamps closer, add a lamp, or pull the product forward |
| Shiny item shows a bright box reflection | Move the product slightly, tilt it, or reduce the size of the opening you are shooting through. For jewelry, see the jewelry guide |
| Yellow background | Room lights are on, or the bulbs are warm. Turn them off or use daylight bulbs |
| Gray background | Raise exposure on the phone, or move the lamps closer |
| Dust spots on the product | Wipe the item with a microfiber cloth, use a blower, then clean any marks in editing |
After the shot
A light box gives you a clean base. Then:
- Crop to the marketplace's ratio, with even space around the product.
- Remove the background and place the product on pure white if you need to meet a strict white-background rule, such as Amazon's main image.
- Export at the size your marketplace wants (if you would rather skip building a set, AI product photography places a product in a ready-made scene): Etsy, Amazon, Shopify or eBay.
Frequently asked questions
What is a light box for product photography?
A light box is a small enclosure with translucent walls that diffuses light from lamps outside it. The light reaches the product from several sides, giving soft, even lighting with minimal shadows and glare. It is mainly used for small products and jewelry.
Can I make a light box at home?
Yes. Cut windows in the sides and top of a cardboard box, cover them with white tissue paper or parchment, add a white poster board sweep for the background, and shine two lamps through the windows. The steps above take about half an hour.
Do I need a lightbox for product photography?
No. For most items, window light and a white card is enough. A light box becomes worth it for small, reflective products like jewelry and watches, or if you shoot in the evening and want a repeatable setup.
What lights should I use with a light box?
Two or three identical daylight-balanced LED lamps, around 5000-6500K, placed outside the box and aimed at the diffusing walls. Make sure they match in color and are the same distance from the box.
Is a light box good for jewelry photography?
Yes, it is one of the best tools for it, because jewelry is reflective and a bare lamp creates glare. See jewelry photography for how to position rings, necklaces and earrings, and how to keep reflections under control.
Why do my light box photos look gray?
Usually the phone exposed for the bright box and the background went gray. Tap the product, raise the exposure, move the lamps closer, or cut out the product and put it on white in editing.
