Red Coral grouper.
Color loss while diving, so how do professional divers get colorful underwater photos ?
👉 As you sink into the depths of the water, light and colors become scarce.
Light is made up of a set of colored light rays. We can observe it by breaking it down more visually using a prism.
This is what happens with the rainbow and its stack of bands of different colors. Each of these colors has a specific wavelength and, to summarize, not all of them penetrate water in the same way.
👉 Using clear water as a reference, it is estimated that: - red is lost from 3 m,
- orange at 5 m,
- yellow at 10 m,
- green at 25 m.
- Blue is the only color that stays at 400 hundred meters and ... in the abysses.
👉 You can take photographs in shallow calm waters and at a short distance from the subject to keep a maximum of light.
👉 The use of an orange filter accentuates the warm tones and preserves the reds and oranges, provided that you stay at a depth where they are still present.
👉 The solution lies in the use of a flash, which will compensate for the lost light and restore the colors in good proportion.
⚠️ Our children and grandchildren will be able to admire this lush life and these shimmering colors, if we preserve the ocean and the life it shelters.
