All symbols that are italicized in the text or tables should be italicized if they appear in the figures. The same size and font of lettering should be used for all figures of similar size in any one paper. Photographs - For accepted manuscripts, one set of all photographs is required. Prints must be of high quality, made on glossy paper, with strong contrasts. Prints for reproduction should be trimmed to show only essential features.
Color photographs are acceptable but black and white is preferred.
