Click on a button for each column to see the two types side-by-side. This tool is designed to help differentiate the nuances of the 16 types and their baseline appearances. Practice by examining adjacent types (i.e. FiSe & FiNe) and try to look at what sets each apart from the other in a holistic manner. Please note that static photos alone are unreliable for discerning type, and this tool is meant only to act as an initial primer as to what the differences are between the types in the most straightforward manner.
Once these 16 vultologies have been archived into memory, this tool is meant to be put aside and forgotten in favor of a dynamic analysis of vultology signals.
