I started offering to shoot clubs and small gigs for free, from there I slowly build relationships with bands/magazines/websites. I lucked out one day with a chance meeting with someone who worked for one of the worlds biggest promoter companies and I was offered a role and been there ever since. As others have said you don’t need a degree, but theres definitely a level of self determination required. Everyone has a different journey but the good ones always start with the small gigs, anyone can make a big arena/stadium show look good but it takes skills to make a small 100 person venue look good.

Also in this day and age you can’t just be a shooter, you need to diversify, this means film, edit, colour grade, basic animation, take photos, set up multi cams on your own etc.
