Choose a simple setup
Use a plain background and soft, even light. Photograph the front, back, sides and visible labels. Keep the camera approximately square to the surface when you want a legible reference image.
Give details their own frame
Take separate pictures of controls, connectors and visible wear. Include a ruler beside the object if scale matters, without covering a label or scratching the surface. Do not retouch damage out of documentation photographs.
Name the files consistently
Use your inventory number followed by a view label, such as CS-001-front or CS-001-label. Store an original-resolution copy and make smaller exports for sharing. Check reflections and background details for private information before publishing.
