Changing the background in a photo is something lots of people would like to do, especially if you often take spontaneous snapshots. It can happen that the foreground of a pic looks OK, but the background has a bunch of unwanted details that ruin the whole atmosphere of the photo. Sometimes, the foreground can be cut out from the photo and put on a completely different background. In this case, you need to make the image background transparent first and then replace the original background with a different picture. Using the transparency of the background you can make stylish promo photos on the white background, beautiful ads, funny pictures, etc. There’s a whole world of possibilities!
