1. Open a photo or drawing of an object you want to make a reflection for.
2. Here I just used the Lasso tool to cut out the car from the rest of the image.
3. I created a new layer and moved it below the car layer, and used the Gradient Fill tool to create a floor.
4. Right-click on the car layer and select 'Duplicate Layer'. Then go to Edit> Transform> Flip Vertical.
5. Go to Edit> Transform> Rotate. Rotate and move the car below the original.
6. Here I deleted the shadow of the duplicated car.
7. Edit> Transform> Warp. Use the Warp tool to move the reflection so it looks like it's on a level surface. You don't have to get it perfect just yet.
8. Lower the opacity of the bottom car. Here's it's at about 30%. Again, it doesn't have to be perfect.
9. Next, use the Eraser tool with a large diameter, low hardness, and low opacity to erase the part of the car farthest away from the original. It should have a faded look.
10. Here I just used the Warp tool again to readjust the reflection, and lowered the opacity a little more.
11. Next, I used the Smudge tool to lightly smudge the edge of the shadow of the original car.
12. I used the Levels tool to slightly adjust the brightness.
13. Finally, I just cropped the photo and merged all the layers.
