How to Remove Image Background?

How can I remove background from an image of a transparent object?

  • I am having hard time removing background from this image. I tried using Magic Eraser and also Background eraser tool. Both of these do not work perfectly. The reason could be the fact that lower portion of this bottle is of glass and it "blends" with the surrounding. Is there an easier way to remove background in such cases?

  • Answer:

    The way I deal with glass is to cut out the glass section using the polygonal select tool and remove it to its own layer. From there I drop the opacity in layers panel to 20% and bump up the exposure buy a little, drop the offset by quite a lot and increase gamma correction quite a bit too. This give a nice transparent effect which isn't perfect but is usually good enough. Example, original on left, altered on right:

use Scott Brown's enhanced method: instead of dropping opacity of "glass" layer, play with its blend modes and levels. hard light seems to work well

There's no easy way to do this. At best, you could carefully erase the entire background from the edges of the images via various tools, but as you state, since it's glass, you'll still see the background color behind the glass, which will likely look funny if you then place this image on any other background.

Copy the image to a new layer. I find it easier to turn off the original layer, also, while I work. With the new layer picked, go to IMAGE/ADJUSTMENTS/LEVELS. Adjust the sliders to get the most contrast you can get in the image. I could get every edge except some of the right lower edge of the bottle to have pretty defined edges. Using the magic wand, select and remove everything you can without running into the bottle. After that, zoom in and clean up with the eraser. Once you are satisfied, select the white area you created, maybe put a very small feather on the edge, turn on and select your original layer, and hit DEL. Voila.

In previous versions of Photoshop there was an extract tool. Now you can use the 'Quick Selection' tool and 'Refine Edge'. Because your image is close to the background you can only do so much with the quick selection tool. So select the 'Refine Edge' option and first change the 'View Mode' to show on black. Then check the 'Smart Radius' and adjust the value, all time view your image to check if you're improving or not really having an effect! You can then use the 'Refine Radius' tool to paint over the edges you wish to subtract. Again in this image I think you might need to use the Pen tool and improve the lines. HTH.
