Isolating a topic from background - please see sample designs. I always use pen tool and cut out (isolate) everything by hand - to make sure the most effective possible quality. Edge feathering (the way how sharp/smooth the border of the isolated object looks) is usually also applied. Custom sharpening is additionally often applied for resized images (example: hi-res images were provided originally, but web size images were needed as a final artwork). Specific effects, like reflections, shine/glow and shadows also can be used Feel Free to contact :)
