Working secretly on the Death Star???
Glad you asked!
I’m working on a video documentary from scratch. The base material contains gobs of home videos and stills, I mean lots of them. Then there are CAD drawings, word docs and spread sheets.
It all comes together with a multi part video.
To prove copyright, I’m not deleting any trial efforts, which are in the multitudes.
It boils down to what others have just said, photography can be a real hard drive hog.
