Here is my attempt at shooting both bubbles (washing-up liquid in water) and oil drops (cooking oil in water). The setup was simple using my EF-100mm macro, a glass dish suspended between two chairs and some coloured paper on the floor lit by a desk lamp. The amount of dirt and lint that gets into the water is very annoying and required some spot healing to remove it.
