Ways to get an alpha channel in multiple images. What would you do?

Question

Design

Fellow designers, tell me, please.
It is necessary to photograph 1000 items of goods and process the images so that in the future it would be easy to change the background for them.
I know that you can do this: take a picture of the product on a certain color background. Then, in Photoshop, change the background to the alpha channel using the magic tool (I don’t remember exactly what it’s called, sorry because of the prescription of years). This method seems to me to be very laborious. Are there tools to make this easier? For example, slip this software the entire catalog with photos and say "do good things"?
Well, or in general, any other option, but easier than I described, even in the same Photoshop or in a chandelier, to put it in your slang.

Answer 1

You can batch change the specified color to transparency in ImageMagick, but you will more than likely have problems on the border of the object and the background, and especially the shadows from the object, if any. Otherwise, the work of clipping objects in the photo would have been automated long ago.
Well, in the photo, any glossy object looks different on a white background and, for example, green.
