Schlieren image of a pond skater (Gerris sp.) and its reflection. The indentations where the pond skater is in contact with the water are clearly visible (black). Schlieren photography is a technique for visualising density changes in transparent fluids. Light passing through a density change is refracted (bent). The imaging method alters the brightness and colour of this refracted light to make such areas visible | |
