<p>UW unless you shoot only natural light at shallow depths on very sunny days or limit yourself to silhouettes, you have to bring your own light source with you. Remember that water is denser than air and bends the light rays as they strike. Reds are gone within about 12' of the surface, and son on, ROYGBIV fading in that order until there is nothing but the great deep blues and violets of the ocean. Besides lack of color, there won't be enough light to take a picture (think of taking a photo at dusk with no flash). Carsten is spot on about the SB105 strobe. When I went digital, I put my D100 into a Light and Motion housing. The SB105 and the power cord are compatible with housings for Nikons. I added a Sea & Sea YS60 slave. Both are mounted on Ultra-light arms, which allow maximum flexibility in your lighting. Just remember that UW things looks ~30% larger and closer than they really are, so adjust your strobe(s) accordingly. If you don't, you will see a well-lit, nicely colored area behind the subject, while the subject itself remains in foreground shadow. Also, most strobes don't throw much light beyond about 7' or 8'; the SB105 is a strong strobe and does that easily. As for lenses, I don't know what your housing budget is, but make sure any lens or lenses you get don't require a dome port unless you're prepared to spend the extra money (my DX12-24 wide angle requires a dome port, and the Sigma 105 macro requires an extension ring added onto the dome port). A good basic UW lens is a 60mm if you don't want to get into the expense of accessories yet. You can get nice close-up portraits, good shots of grouper and great macro. You won't get UW vistas, wall shots, tiny, tiny critters (the 105 is great for that, but you gotta have accessories). You will be so much happier with your D70 UW results. Final thought - UW it really is all about the light and learning how to use it - when to not use a strobe, how to shoot natural lighting, how to adjust your strobes...and digital flattens the learning curve and eliminates the wait and expense of E-6 processing!</p>

In the Galapagos life can be harsh. In the wild, nothing can be altered by man; all must

be left "as is."<div></div>
