I am pondering the following question, is there a typographical convention for which of the following choices should be prefered?
The background is:
- I want the title style in small capitals.
- fMRI is a common abbreviation where the first letter is always lowercase (which in other font styles is a minuscule).
- Small capital f might be the representation for lowercase f in the chosen font style, but it makes thee abbreviation less recognizable.
- Whereas most words are capitalized or not depending on the surrounding punctuation, fMRI is never capitalized, therefore the word recognition is more affected by the switch from a minuscule to a small capital.
If there is no such thing as a convention, which would you recommend?
