Hi,

I think you should keep reflections on it, so it would look realistic. Using the same image you provide, you can try this:

– Use Color Range to make seletion on most of the object (grey part)
– Erase them with low-opacity Eraser (e.g. 30%)
– Then add more contrast to it (use Levels or Curves)

Please see this example:

Hi Jiri,

I think you can try these 2 ways:

Option 1:
– Use Color Range (Selection > Color Range) to make selection of the background
– Delete background
– Run Layer > Matting > Defringe (eliminate white edge)
Done

Option 2:
– Open Channels palette
– Duplicate Red (or any channel has great contrast)
– Image > Apply Image: Blending mode Overlay (Opacity 100%)
– Load selection from duplicated channel
– Add layer mask
– Retouch if needed
Done

Below you can find the result comparing to the original background.

Regards,
