The sea is a fundamental element of life. Writers, poets, and philosophers use its image in all its fluid and metaphysical aspects. Human beings are constantly challenged by the sea. They cross its surface to go deeper. Immersed, they surrender guided by sensations and nature. The images presented here reproduce the perspective of someone contemplating that universe. The photographs were taken underwater with the aim of experiencing various sensations such as lack of balance, vertigo, tension, harmony, continuous movement, the sound of the sea, and the taste of salt. To photograph underwater, vision alone is not enough. The whole body is involved, utilizing all five senses. The camera is positioned low on the horizon, and the waves become moving mountains. In this way, physical and psychological aspects are affected. The pure landscape and the expressive idea are not resolved. One enters a world of subjectivity. In the water, equipment and lenses take on new forms, creating new interpretations.
