What does it mean when someone describes a flash as deported?
Is it the same thing as saying a flash is "off camera?" Or is there something else which is also needed to qualify it as deported?
From context, I think it just means "off-camera flash", or "remote flash".
I think this is an accidental import from French (le flash déporté), and not a common term in American or British English photography usage today. Particularly, the person who used it on this site, prompting this question, is a native French/German speaker. And, many of the quotes Rob found also appear to be from native French speakers. That in itself doesn't mean that it isn't legitimate English, but it may be more something common to French speakers of English than to American or British English.
Meanwhile, the phrase "deported flash" is not found at all in a Google Ngrams search. I did find "deported ring-shaped flash or with deported satellite flashes" in a book about finger- and toenail diseases (warning: gross!) — but, hey look, at least one of the editors of that book has a decidedly French name.
Of course, English doesn't have any ruling body dictating what words are legit or not, and we borrow words from other languages with gleeful abandon. So, it's possible that this is emerging usage, or will be soon. To me, though, the word has decidedly negative connotations, and particularly in today's political world with migration being a sensitive topic, I don't think it's likely.
To position the flash precisely and off-camera in a manner such to enable more than 'simple lighting' but also enhancement of surface features (such as in the photography of embossed glass or reflective surfaces).
I've found a few references to that terminology.
From a webpage about a course on underwater photography:
"During our PADI Digital Underwater Photographer course, you will learn when to use a red filter, how to use an integrated flash and a deported flash, the rules of composing a beautiful photo, ...".
"What are you needs ? Are you shooting in a studio or anywhere ? Only one deported flash or do you plan to get more later ? Do you need TTL metering or manual flash is Ok ? – Olivier Sep 18 '16 at 17:35".
Comment by Zorak on the DPReview Forum:
"Fact is I do not plan to use complex or deported flash systems, I just want a good and small flash for the parties, birthdays, etc, and all the Sony Flash are big. It defeats a bit the purpose of the camera, being small and "unobtrusive" (yeah, I know, a flash is never discreet).".
"The macro mode allows you to get very close to the front lens (something like less than 2cm), but the wide angle is not too adapted for macrophotography, and the deported flash even less.".
