Excellent pics, Graeme. The light and depth of field on the final picture is superb. Here is my Rotala rotundifolia in my 120l taken before the tank was stripped down. The pictures were taken with a Nikon D40 on a tripod. The white balance was on auto and I just used exposure compensation to underexpose it a little. All I need to do now is start learning some Photo Shop techniques....and buy Photo Shop. Dave.
