Many
times, we simply want to capture our reef system without the surrounding
cabinetry. In capturing our little slice of the ocean, we simply need
to add a couple of techniques to those we picked up from shooting the
entire tank.
When shooting the entire tank, we shot at an angle to give the viewer a feel for how it looks in three dimensions. Although we went through pains to ensure the tank was properly exposed, the composition was meant to be viewed holistically. Therefore, we were not overly concerned with depicting the contents of the tank in the best possible manner.
Taking care to line things up perfectly will result in less perspective distortion and avoid a downhill slant or skew to the image.
If using interchangeable prime lenses stay around 50-85mm to reduce these effects.
When cropping our shot try to avoid the surface or a break in the water's surface as light may shine through and become a distracting element. If the surface of the water and the water column above the top of the reef ecosystem does not add anything to the photograph, crop it out. We also want to crop out the walls and the deep sand bed as they add nothing to the photograph, either. The result is a photograph of a slice of ocean that appears open and self-contained, rather than being a piece of ocean thrown in a cramped up box.
