To use your own photo as a background in Photoshop, you need to use the Layers panel to add the photo as a new layer behind the background layer. Then, you can choose and adjust the layer's clarity, color, and fill method to make your photo the background. The specific steps were as follows: 1 Open up your Photoshop and choose "file">"new">"layer" to create a new layer. 2 Drag the photo to the new layer to make sure that the photo is placed in the correct position without affecting the other layers. 3. Choose the photo and choose the "copy" button in the "Layers" panel. 4 Open the new layer panel and choose the new layer. In the Layers panel, choose the "New fill or adjust layer" button and then choose the "Opacity" tab to set the layer's Opacity to about 20%. 5 adjust the fill or color of the layer. Choose a different color or pattern to fill the background according to your needs. 6 If necessary, you can use the fade tool or other tools to create a texture or pattern to fill the background. 7 Finally, you can close the Photoshop file by going to 'Files'>' Close'>'Close Files'.
