Hi Vivid-Pixers,
In many respects digital photography has a lot in common with analog photography, meaning the use of film. For example both digital and film cameras use f/stops, shutter speed and ISO to govern exposure. Another commonality is that at depth the use of strobe light is required to “paint in” colors back into foreground elements. If not for the use of strobe light those colors would be lost from the selective filtration of...
While there are many techniques for sharpening, some yield better results than others. We have selected one with a counterintuitive name...Unsharp Masking. Why? Because it tends to accentuate the important parts to the image without increasing visual noise or graininess.
As Marshall McLuhan said, "The medium is the message."
While I'm not so sure he was talking about underwater photography, the principle is similar. The medium in which a signal travels influences the information received. This not only happens underwater, but topside is well. The sky tends to be blue (where you dive...not here in Rochester, NY, where gray is the dominant color) because of the differing interaction between atmospheric molecules and wavelengths of light....
