Image manipulation and the question of ethics.

In a world of changing technology, image manipulation has become easier to achieve than ever before in the history of illustration. The quality of computer-generated images is such that it is difficult to distinguish them from a conventional photographic image. This article asks whether the industry can, and should, set controls to regulate itself before regulations are set for it by outside agencies. It discusses possible conflicts between ethical questions associated with image manipulation and the rights of image makers to produce creative images. Reference is made to historical incidents of image manipulation for propaganda; and technological advancements which make possible seamless montages of images using computer software programs and colour printers.

A SCUBA-diving fatality.

An investigation by a Naval Board of Inquiry into the circumstances of a fatal naval diving accident is presented. Although drowning contributed to the fatal outcome, massive arterial gas embolism is thought to have been the principal cause of death, and the value of post-mortem computed tomography scanning for its detection is demonstrated. The possibility is discussed of diver error due to unfamiliarity with equipment and procedures, compounded by nitrogen narcosis. The shortfall in expertise of coronial inquiries into diving deaths is emphasized against a background of increasing popularity of sports diving around Australia. The implications for the offshore industry are obvious and suggest the need for a federal diving inspectorate.
