Nikon D300 & D90 Best Underwater Settings for Macro
This is the first part in a series where we discuss camera settings when shooting fish, wide-angle or macro underwater photography, with a Nikon or Canon setup.

Initial Settings for the beginner dSLR underwater macro photographer
Shutter Speed: 1/320th for the D300 or D300s, 1/200th for the D80/D90. 1/250th for the D7000. If you are using a D300, Check your E1 custom menu setting, see the bottom of this article.
ISO: 200, ISO 100 for the D7000
Strobe power: Set it manually, or use that TTL converter that you paid dearly for! I've done both, each has their pros and cons.
Understanding the finer points of adjusting Aperture, Shutter-speed and ISO are best covered in an in-person underwater photography class. But we will talk about changing these settings in a future article.

Quality: I like to shoot in RAW + small fine JPEG, on a SanDisk Extreme memory card. This doesn't take up much more space than shooting only in RAW, but I have a jpeg ready for a quick posting. Read about choosing raw or jpeg.
Focusing mode: Spot focus. Learn how to move your focus point around.
Light metering: doesn't matter
White balance: Auto. Effects JPEGs only. Read more about color temperature.

Focus priority mode - single-shot focus.
If your camera has continuous focus mode, also called servo-focus mode, that means the camera will continuously focus, and allow you to release the shutter at any time. I often use this mode with low-contrast subjects, in low-light, and when doing supermacro. This article on low-contrast underwater photography may be helpful. I adjust this with my C/S/M switch on my Nikon D300, and I use this switch often.
Less important Nikon D300 / D90 underwater settings:
Color space (for dSLR users, effects JPEGs only)
dSLRs have the option for shooting in adobe RGB, or sRGB. Adobe is a larger color space, is better for printing, and is the recommended color space. However, you might have to convert to sRGB for posting photos to the web. sRGB is the color space used on monitors. There are also other color space options, but these are beyond the scope of this guide. There are entire books out on color spaces.

Vivid mode (effects JPEGs only)
When shooting in JPEG, underwater photos can often look better in vivid mode, especially since color saturation is sometimes reduced lost when light travels underwater. Give it a try, you can always turn it off if you think your photos are coming out too saturated. Objects that are very red can get oversaturation, so if you are shooting JPEGs, you might want to turn this setting off, or make sure you don't overexpose.
High ISO noise reduction (effects JPEGs only)
Many dSLRs have a setting for High ISO noise reduction, which will be turned on only for ISO above a certain number, e.g. ISO 800 or above on the D300. I leave mine on normal, but some people prefer low or off, since the noise reduction is in effect slightly blurring the photo.
Sharpness (effects JPEGs only)
I usually keep this at normal.
Custom Menu Settings
I turn off my AF-assist light (A9 on my D300)
I turn my flash-sync speed to 1/320th (E1)
My dynamic auto-focus area is on 51 points (A3).
My LCD illumination is turned on (D8)
