How ever you are taking pics they are clear and separated from the background some of us take years to get that good. When I did my photographic trade course the head instructor had a thing about mounting all pics on black back grounds and of course to be marked well we all conformed. Quite a shame really. Take a look at George Watkins post on todays page gradual hued backgrounds. You will recognise his work it is mainly small boxes and containers of class.
