What aspect of visual information is outlined in DoDINST?

The aspect of visual information outlined in DoDINST refers specifically to the alteration of official imagery. This focus emphasizes the importance of maintaining the integrity of official graphics and images used in communication, which is crucial in ensuring that representations and modifications align with established guidelines.

In military and official communication contexts, the alteration of imagery must be approached with caution to avoid misrepresentation or degradation of the original message. Ensuring that any modifications adhere to specific policies safeguards both the reputation of the institution and the accuracy of the information being communicated. This is particularly critical when images serve functional or symbolic purposes within military documentation and public representation.

While the other choices suggest relevant topics related to visual communication, they do not directly connect to the core regulations established in DoDINST regarding how official imagery may be appropriately altered. Thus, the emphasis on alteration reflects guidelines necessary for preserving the authenticity and intended impact of visual communications within the specified context.
