Masking glass

Hi,
I am shooting some high key glass images, and I am looking for optimal solution for masking them from the white-gray background. To make it easier, here is one of the images:

So far the best method I found is to create path by using Pen tool and cut out all the background with the reflection as well. However it is very time consuming, and so I am looking for any tim that can speed it up.

I tried to play with the layer blending, find edges+invert but no result was satisfying (may be it can work on small image, but the original image has hight over 5000 mpx, and should last like that). Each time I lost some edges.

I would be glad for any idea that can speed up the masking (ideally something that would take couple of minutes ;) ).

Thank you for any idea.

Regards
Jiri

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,

Hi,
thank you very much for the advice. I tried both, it somehow works for me (at lest for bow and stem), but the foot ... I was not successful there. So probably I will see if I can mix this with the path (and get the quick result). At the end, I like to keep all the whites within the glass and so their gradients, but remove the reflection and the "outer" background.

Your result is very impressive. My final result should be something like this (ok this is one of the final results).

Thank you one more time.
