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.

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)

Awesome! Thanks for the answer - how would you suggest I refine it? –  jacktheripper Nov 30 '12 at 18:47
    
As I posted, a bit of a levels or curve adjustment on the mask to get those last bits of background. Then some Hue/Saturation adjustments to pull the yellow out... you basically have to experiment with a few options to see what works best. It's really not the greatest photo to work from. –  Scott Nov 30 '12 at 18:49
    
How do you apply levels or curve adjustments to the mask? –  tobinjim Aug 16 at 21:05

@tobinjim click the mask thumbnail in the Layers Panel and choose Image > Adjustments > Levels (or Curves) –  Scott Aug 16 at 21:47
    
Well color me noob! There's even a pop-up there for which channel you're working on! These clever folks. –  tobinjim Aug 16 at 22:33
