I look forward to this shoot as its very sciencey. Essentially I've ordered a childs toy but no one has to know that. I plan to setup an infinity curve using black paper rather than white this time, in the hope that the photographs will look different. I'll set my camera up on my tripod and place it right infront of the tank. From there the rest should be simple. Once I have the sand I can construct the different shapes and sculptures before I take the photographs and then I can experiment with different shutter speeds etc. For this shoot I will have to use a small aperture as I'll be up really close to the tank. The small aperture will allow for a narrow depth of field, which will help with the focus and sharpness of the images.
