Short answer: photograph your subject against a plain background, cut them out, place them on the backdrop, and match the light, size and shadow. The rest of this guide shows each step and the mistakes to avoid.
What is a digital backdrop?
A digital backdrop (also called a digital background) is an image file that replaces the real background of a photo. Instead of hanging a printed fabric or building a set, you photograph a person on a plain background and put them into the scene on a computer, in an editor or in photo booth software.
The backdrops on Digital-Backdrops.com are empty scenes: a room, an arch, a flower wall or a beach, with a clear floor and no people, text or logos. They are AI-generated original scenes, each reviewed by a person before it is published. The library has 102 scenes today, and every scene comes in three shapes cut from one 2880px master: landscape 2880 x 1920, portrait 1920 x 2880 and square 2880 x 2880 pixels.
What you need
- A photo of your subject, lit evenly, on a background that is easy to remove.
- A way to remove that background: a green screen with chroma key, the AI background removal in booth software, or a photo editor such as Photoshop, Affinity Photo or GIMP.
- A backdrop file. Start with the free 1280 x 853 preview to test the look, then use the high-resolution file for the final image.
Step by step
-
Step 1: Pick a scene that matches your photo
Check four things on the scene page: where the light comes from, how many people fit, standing or seated, and the camera height (our scenes are drawn at eye level). Matching these at the start saves most of the editing later.
-
Step 2: Photograph your subject to match
Light the person from the same side as the scene. Shoot at the same height. Use a plain, evenly lit background (a green screen, a grey wall or a white sweep) so the edges are easy to cut out.
-
Step 3: Separate the subject from the background
A green screen and chroma key, the AI background removal in your booth app, or a selection tool such as Photoshop's Select Subject all work. Check hair and hands at 100% zoom.
-
Step 4: Place and scale the subject
Put the backdrop on the bottom layer and the cut-out above it. Scale the person so they fit the room: a door is about 2 m (6.5 ft) tall, a dining chair seat is about 45 cm (18 in) off the floor. Keep feet on the floor line.
-
Step 5: Match light and colour
Adjust brightness, contrast and colour temperature of the subject until skin tones sit in the scene. A warm scene needs a slightly warmer subject; a snowy scene a slightly cooler one.
-
Step 6: Add a contact shadow
Paint a soft, dark shadow under the feet (or under a seated subject) on its own layer, set to Multiply, and lower its opacity. This is the step that stops people looking like they float.
-
Step 7: Export at the size you need
Export for print or screen. The high-resolution files are up to 2880px, so a 6 x 4 inch print or a full HD screen is covered without upscaling.
Choosing a scene that will look real
Most composites that look fake fail before any editing starts: the scene and the photo do not match. Each scene page lists the light direction, light colour, group size and pose, so you can choose before you shoot.
- Light direction. 51 of our 102 scenes are lit clearly from the left or the right. If your subject is lit from the left, pick one of those lit from the left. Scenes lit from the front, from above or softly from all round are the easiest to match.
- Group size. 37 scenes have room for four or more people, which suits families and photo booths.
- Pose. 51 scenes work for seated subjects, with a sofa, bench, rug or clear floor at the right height.

Common mistakes
- Light from the wrong side. The shadow on the face points one way and the scene's shadows the other. Flip your subject or pick another scene.
- Floating feet. No contact shadow, or feet cut off above the floor line. Add a soft shadow and keep the feet in frame.
- Wrong camera height. A subject shot from low down placed in an eye-level room looks too tall. Shoot at about chest to eye height.
- Wrong size. Compare the person with a door, chair or arch in the scene, not with the frame.
- Hard, bright edges. Green spill or a white halo around hair. Use your editor's edge refinement or a spill removal setting.
Free or high resolution?
The free file is 1280 x 853 pixels in landscape, with a small Digital-Backdrops.com mark in the bottom-right corner. It is fine for testing, proofs and small screen use. For prints, client work or a clean look, use the high-resolution files (up to 2880px, no watermark), which come with lifetime access for $27 once. Both carry the same licence rules.
