SegmentitThe best photo is not necessarily the most dramatic one. For reconstruction, look for an image that makes the shape understandable. Use this short capture routine before choosing your input file.
Decide what should become an object
In a crowded toolbox, two green handles may look alike. Choose the right subject before framing it. If you can move the object, set it apart; otherwise, change your viewpoint to make its edges easier to follow.
A white background is not a requirement. A white object against white can lose its outline. Look for useful visual separation between the subject and its surroundings.
Show several dimensions in one view
For furniture, try a three-quarter view that reveals the front, a side and part of the top. For a long tool, make sure both the handle and tip remain visible. The aim is to explain this particular shape, not apply one camera angle to everything.
Leave a little space around the subject. A leg cut off by the image boundary does not become observable just because the photo has a high resolution. Keep an uncropped copy so you can revisit your framing.
Keep lighting from hiding the edges
Soft light is a useful starting point. Adobe’s 3D Capture documentation advises avoiding extreme contrast for photogrammetry and discusses the difficulties of reflective surfaces. These visibility principles also help when preparing a single reference; they do not guarantee a generative model’s result.
Try a shot near a window without direct sunlight, then inspect it. Does a reflection conceal part of the handle? Does the underside of the chair merge with its shadow? Move the object or light and compare the two shots.
Check the file before uploading
Open the photo at a useful size rather than relying on its thumbnail:
- Is the outline sharp, especially around thin parts?
- Are all the object’s extremities inside the frame?
- Does a neighboring object appear to merge with the subject?
- Has a portrait-blur effect erased an important edge?
- Has the file kept enough detail after being transferred?
Prefer the original file to a compressed screenshot. If focus missed the subject, taking another photograph is often a better starting point than artificially enlarging the image.
Keep reference views for inspection
Even when your chosen workflow takes one input image, keep views of the back and underside as inspection references. This does not mean those views will automatically be used during reconstruction.
A photograph cannot reveal hidden surfaces. For a piece intended for a room layout, record its actual dimensions separately. You can then check scale in your interior project.
Once you have chosen the image, move on to object selection and the photo-to-3D workflow.
What if selection remains difficult?
Compare two photographs instead of repeatedly correcting the same image. If the background matches the subject, move the object against a contrasting surface. If a handle merges with the body, change the viewing angle slightly. If an edge is cropped, step back to include the whole object.
Once the shape is clear, refine the mask to remove remaining scenery. Keep the original photo for comparison with the final model: better selection cannot replace information missing from the image.
Before opening the Studio, check your image dimensions and review the photo preparation checklist.
