Nikon D7000 underwater settings

I have finally put together a page of all my settings with brief explanations.

This is for Nikon D7000, Ikelite, Inon Z220 strobes, macro, wide angle, split levels and video.


Ikelite housing with Inon Z220 strobes, one triggered by wire sync cord and the other slaved via fibre optic cord. Manual Aperture, Shutter speed and flash power.

Initial setup

Movie Settings - Manual Movie settings
ON (for manual video exposure) or OFF (for auto exposure)
Custom Setting Menu
a8 - Live view/movie AF - Autofocus mode - AF-S (AF-F does not work well enough)
f6 - Menus and Playback OFF (Control dials change A and S rather than image displays when image review is still on)
f7 - Release button to use dial (Activates sticky buttons. Tap and release a button, like ISO or WB, and then make changes with the control dial)
White Balance - 5260K for stills. Auto or manual WB for movie

Macro
Lens - Nikon 60mm f/2.8D AF Micro Nikkor and flat port
Quality - RAW 14bit plus fine jpeg (Often just use the jpegs)
Aperture - f/22 (For max depth of field)
Shutter speed - 1/125th (Fast enough to avoid camera shake in ambient light areas)
ISO - 100 (Plenty of light available from close strobes so use lowest ISO)
Flash Power - Adjust as needed (Usually around -3.0)
Focus - AF-S with Single or Auto 39 AF points (I often pre-focus on something then hold down the AF lock lever then recompose with the most important feature in focus)

Wide angle

Lens - Tokina 10-17mm DX fisheye with 6" dome port and cut away shade
Quality - RAW 14bit plus fine jpeg (RAW much more useful for wide angle. Captures smoother tonal gradation in background water and sunballs. Also allows colour cast adjustment without loss of tonal smoothness)
Aperture - f/8 (Depth of field is not a problem, especially with fisheye lenses)
Shutter speed - 1/60th then adjust to balance ambient exposure with flash
(Shooting towards the sun will need faster shutter speed and smaller aperture)
ISO - 200 (Or higher for deep ambient light shots)
Flash Power - Adjust as needed
Focus - AF-S with Auto 39 AF points
WIDE ANGLE photo gallery

Split level

Lens - Tokina 10-17mm fisheye with 8" dome port. (The extreme wide angle of view and larger dome port are essential for sharp split levels. Need to spit on the dome and rub around to reduce drips in the top half. Dip under water then shoot as you lift up out of the water)
Quality - RAW 14bit (Allows exposure adjustments in Photoshop without reducing the image quality too much, especially the underwater half)
Aperture - f/16 (Need the depth of field to keep above and below sharp)
Shutter speed - 1/125th (or faster to freeze water movement and avoid overexposing the brighter above water areas, like clouds)
ISO - 400 (To allow f/16 and faster shutter speed)
Focus - AF-S with Auto 39 AF points. (Pre-focus on the underwater subject then hold the AF lock lever)

Video - Wide angle
Lens - Tokina 10-17mm fisheye with 6" dome port and cut away shade
Quality - 1080 24fps high quality
Aperture - f/5.6 (Have to exit live view to change aperture)
Shutter speed - 1/50th (or as close to 2 times the frame rate as possible)
ISO - Adjust as needed (This is your main exposure control for video)
Light - Diffused UK Light Cannon HID torch. (Proper lights would be better)
Focus - AF-S with Auto 39 AF points.
(Prefocus for each scene. Continuous AF (AF-F) is too slow and lens focus noise is intrusive)
VIDEO gallery

Video - Macro
Best done on a tripod to avoid camera movement.
Lens - Nikon 60mm f/2.8D AF Micro Nikkor and flat port
Quality - 1080 24fps high quality
Aperture - f/22 for greater depth of field
Shutter speed - 1/50th (or as close to 2 times the frame rate as possible)
ISO - Adjust as needed
Light - Diffused UK Light Cannon HID torch. (Proper lights would be better)
Focus - AF-S with single point. Prefocus carefully for each scene.
