A clear, well-lit photograph where the subject has a defined edge against a contrasting background. Almost every edge problem comes from the photograph rather than from the processing, because hair against a busy background, motion blur, low contrast between subject and background and translucent materials are all genuinely ambiguous at the pixel level, since there is no sharp line in the image where one thing ends and the next begins. Where the source material is unclear, no amount of adjustment produces a perfect result; working from a clearer photograph does.

Check the outline at full size and pay particular attention to hair, fur, glasses and any fine detail that overlaps the background, since the interesting part of any background removal is always the boundary. Where an edge looks cut out, harsh or fringed, the edge softness can be adjusted, which resolves the majority of visible problems. If the source was too low resolution to begin with, though, no setting will help, because there is simply not enough information in the file.

Several categories are genuinely difficult for any automated method, and it is better to recognise them than to keep adjusting settings. Semi-transparent material such as glass, lace, fine netting and hair rendered against a bright background has no clean boundary, because you can legitimately see through it. Subjects that are almost exactly the same colour as the background give the detector nothing to separate, so the result will be patchy no matter how the processing is tuned. Very low resolution photographs produce soft, blocky edges regardless of detection quality.

Both are available. Keep the transparent background when you are compositing into a design, and place the subject onto a solid or white background when the destination requires one, such as a marketplace that will not display transparency. The choice of new background matters as much as the cut-out itself, because a subject lit from one direction placed on a background lit from another looks pasted on, since the shadows and highlights disagree. A plain neutral background blends more convincingly than a detailed scene.

Usually because the background does not agree with the original lighting. A subject lit from one direction and placed on a background lit from another looks pasted on, because the shadows and highlights disagree. For consistent results, a plain neutral background blends more convincingly than a detailed scene, and matching the colour temperature of the original lighting is the single most effective thing you can do. For product work specifically, an even neutral background with soft, consistent lighting produces results that look deliberate rather than processed.

They are removed along with the original background, so a subject that was sitting on a surface loses the contact shadow that made it look grounded, and adding one back afterwards is a matter of judgement. Similarly, anything behind the subject in the original image is gone permanently. Where a complex original is involved, the honest answer is frequently to use the tool for straightforward cut-outs and handle the difficult images individually.

A single clear subject with a distinct outline is the easy case and is handled very well. Groups of people, crowded scenes, reflections and objects that overlap each other are progressively harder, because the tool has to decide which object an ambiguous edge belongs to. Working through images one at a time and checking each result keeps quality high, whereas batch processing a large folder and assuming the results are uniform is how a folder full of subtly wrong cut-outs gets produced.
