To make these images, we had to take the original image (image that includes the model) using different objects as props. Then we used photoshop to add a mask layer of the empty background and used the brush tool in black to remove the stool, and use white to recover parts of the original image in case I removed too much.
A mask is an invisible film that can be drawn on,  I used one to cover parts of the model's body and stool by using an image of the empty background, unlike the erase feature which just gets rid of the image. I had a lot of fun taking and making these images, so I can imagine myself using my new knowledge to create more complex images that look like they have levitating items, or have parts of the model missing, for example, I could use it to photoshop a flying, self-driving car from the future.
