Create Action to Remove White Background in Batches

If what you want is to just delete a color or range of colors in a batch process, then that is easy

(i.e., like in PowerPoint where you can select a color to become transparent).

Before you write your action, from the main menu go to {Select}{Color Range} and select the color (or range of colors) you wish to become transparent. For white, just use the eye dropper to select white on an image or on the swatches pane. Save the section result.

Now write your action: Open new action...

1) Open image

2) Set background (that is if you will import a flat image it will be in a background layer, just click on that layer and accept the option to change it to "Layer 0")

3) Do {Select}{Color Range}, but this time "load" the color selection file you previously saved

4)<Ctrl><X> ... removes the selected color

5) Save image

Save action, Run batch: Done.

If you prefer, steps 1 and 5 can be handled by the batch process rather than in your action.

Caveats: If the background color(s) is also in non-background areas it will get deleted there also.

The back of the glass is a bit tricky but if the backgrounds are consistent, you may write an action that:

1. Trashes the background layer lock and places a new layer below the object layer

2. Calls up Blend If with the setting shown here.

Then you have the option to save perhaps a flattened version of the image and a psd version, as well.

Click on the image below to see the Blend If setting more clearly.

Much depends upon whether the subject in each image is in sharp (edge) focus and whether the white background in each image is of a common tone value. It would be helpful if you posted a few images so that we can provide practical advice.
