Maximize match accuracy with these simple photography practices
Avoid harsh shadows or direct flash glare. Natural daylight or neutral indoor room lighting produces clear stud contrast.
Isolate one brick at a time on your surface so the model doesn't confuse neighboring elements or stud connections.
Place the piece on a clean white, gray, or black paper sheet to prevent patterned tablecloths from interfering with outlines.
If a piece has printed graphics, unique side clips, or specialty bevels, position it so those features face the camera.
Ensure your smartphone camera is focused on the top stud text or mold lines rather than blurry background objects.
For tricky slopes or modified plates, take a photo of the bottom tube structure — our reverse stud tool excels at bottom profiles.
