A word or expression to describe photographers, film makers

Solution 1:

The informal lensman (American-English, Oxford Dictionary):

(A professional photographer or cameraman.)

Otherwise there is no formal alternative; you'll just have to combine:

Photographer+Videographer

Compound a new word: photovideographer or photo-video-grapher or (photo/video)grapher

If we google some of these options:

"photographer/videographer" 490,000 results

"photo/videographer" 67,000 results

"photovideographer" 2700 results

(note, 'photo' should go before 'video' because a video photographer is actually still just a videographer.)

You could use cinematographer but a cinematographer doesn't physically operate the cameras, he directs others to do that.

You also wanted an option for all of that + audio; for that you could use multimedia producer or multimedia creator, although videography can encapsulate post-production audio editing as well.
