Thanks for responding to this – I appreciate it. What I mean by sub-category, such as Zoology, Botany and General in Nature, is that while the Nature competition is considered a single competition, the image scores are ranked separately within each sub-category and awards are determined separately in each sub-category and for each member Division (Beginners, Advanced and Masters) as far as Honourable Mentions and Runner Ups go. There is still only a single Top award per member Division, and a single Best of Show award selected from the 3 Top images.
