I was washing the dishes while seeing the reflection of the sponge though the glass of water. I put the glass of water on the sponge. It was a little bit dark inside the house so I tried on the grey wooden floor. However, the wood was so visible darkening the pic. Therefore I used a sheet of white paper under the sponge instead. I resized the pic and finally changed the color. It is fun to experiment on the things around you. And why not?
