I was a professional sound engineer for many years, working in DDDD (Digital recording, Digital editing, Digital production and Digital post production) in both music and audio for educational CD/DVD
Here's a little outtake from between sessions, we used to record for up to 12 hours a day, smetimes it gets to the artist !! Timgoes madⓘ
I had a printing business, but I specialised in DTP and typesetting (well it wasn't really that but there isnt a name for it in the digital world as far as I know lol)
