What did the photographer try to focus on? The middle
section of this dented member is in focus, but not the
portion closest to the camera. A f-stop setting of 1.4 was
used. A higher f-stop should be used to increase the
distance range that is in focus. Of course, this will require
higher light levels too.
A decent shot of a break in a pipe. Notice how the diver
started rotating his hand when the upper half of the picture
was exposed (SharkEye was using a rolling shutter), so a
shorter exposure time / more light would help.
A scientific instrument photographed with 6.5 mm lens. The
field of view exceeded the beam width of the ROV light.
Perhaps a second light could have filled in the background.
ROV operates a core sampler. More even illumination than
the last picture.
