Alpha Transparency Remove Background Photoshop


Is there any way in Photoshop to remove a background color from an image, when some of the background is behind a transparent object.


So far, I've tried using masks and channels but have not made any progress. I want to make the background transparent, so that the bottle and 'ink' can be put onto a white background colour.



Many thanks in advance, any help would be much appreciated.

Answer



There's no automated way to set a color as transparent.


However, try Select > Color Range and choose "Yellows" from the drop down menu. Then create a layer mask based on that selection. You get some decent results.


It's not perfect. But it's then a matter of adjusting levels on the mask a bit and correcting for the color halos, just general refining.


Mask created after color range selection.... (no refinement)
