Very good wide angle shoots Wolverine the Black-tipped Fusiliers and coral exposures were right on. I am not so sure this or any other point and shoot can handle a sunball or a large difference in exposure very well, even if the apertures can go down to F22 or increasing the shutter speed.
The reason I believe is that the PS does not have a mechanical shutter curtain and a mechanical aperture like the SLRs. The PS does this electronically by clearing the CCD sensor and constantly reading the data from the CCD chip. Since the over exposed light is always hitting the pixels and cannot adjust quick enough or is beyond its exposure range, the pixels have no choice but to produce “noise”. This probably why PS aperture openings have a limit of F8 electronically.
You may try and experiment with a -2 stop neutral density filter in front of your lens to bring the light levels to a more “workable” level for the CCD chip’s range or not include the sun altogether. Oh and this problem also occurs on land shots as well as UW. And thanks again for sharing those jewels of the Sulu Sea.
Sidenote:
The first image of the Gorgonian coral is the reason that for me personally, including the sun should NOT be a priority in taking the picture. By including the sun in the picture it forces one to shoot at an angle that is not as suitable or fitting to the subject, like a side view of the Gorgonian almost lost in a crowded reef.
I hope you taken other shots of the Gorgonian close up frame filling, edge to edge coral, at an upward angle towards a cobalt blue open water. The colors of this type of coral can be blood red at its branches with some beautiful yellow tips.
