These pics are not made using Photoshop.
To make one, you will need:
- Glass container or anything transparent
- Anything flat and colorful (in this case, a door rug)
- Macro lens (I used a Raynox DCR-250 macro conversion lens)
- Put the glass container on the rug.
- Pour the water and oil in the glass container. Stir a little.
Tip: Avoid places that has wind and dust unless you want tiny specks in your water+oil macro shot.
