This is an interesting question, especially for documentary filmmakers who need to present expert names and titles consistently on screen. I think keeping JR. in uppercase makes sense when the entire lower-third title uses capital letters, while names like McDonald may benefit from preserving their original capitalization for readability. Consistency is probably the most important factor. Another challenge documentary teams often face is finding the right experts and contacting organizations for interviews. An Email Finder can be useful for locating publicly available business contact information on official websites when researching potential interview sources. Great discussion about the small details that make professional productions look polished!
