Don’t be fooled. Yes, white backgrounds are possible with just good lighting. And many AI tools (apps and web services) promise “easy background removal” - but they will quickly disappoint you. But pros use path editing tools to produce perfect antialiased edges. Nothing else comes close. Traditionally done in Photoshop this is now possible on a smartphone. On the lower left is the original image (already cropped). On the lower right it is open in Exacto, an iOS/Android app (watching the short help animations is a must to learn it). The blue dots are anchors and black ones can pull curves between them. Easy zooming on a smartphone makes the process practical. Exacto exports to Photos with a transparent background. This method makes busy backgrounds a non-issue, lighting can be focussed on how the object looks rather than the delicate balance of white background and a washed-out object.
This is the same piece in sunlight and a fluorescent flood lamp. The picture was taken by an iPhone and then cropped to a white background using the path tool in Photoshop. The whole mug is glazed with GA10-B. The inside and upper outside of the leather hard piece was engobed using L3954N.
From ceramic production to pottery we need to take photos, knowing something about the file formats and working with them saves money, time, the environment.
