>>4500238To be honest, I don't think you can really fuck it up. A lot depends on what the organizers expect, of course but you can check their official profiles/media beforehand to get a grasp on what kind of photography they like to post later. But using actual camera with good lenses puts you ahead already. You don't have to apply right away, when I was starting I was just shooting from the crowd, learning along the way (and was surprised how many people treated me as "official" solely because my camera looked "professionally" enough), when I felt more confident I sent organizers some photo on my own, as happy participant sharing his work. When I finally applied, they remembered me because of that, later I could use this whole "...and I was shooting for X guys before" as an argument for other applications.
>Was your IG enough to get brought on or did you require your own site?Site is much older than my IG, which I made literally few months ago so I rather provide site link as it makes much better impression than pitiful IG account with 5 carousel posts and low amount of followers. I think any kind of online portfolio works well.
