I have an MA in Digital Media and objectively they’re technically decent, bar small things like not using a diffuser to get the sun out of Alex’s eyes, but the photographer who shot Perrie and Alex for Vogue also didn’t bother with that!
Subjectively, I think they’re just alright, they don’t go to anything beyond glamour shots so there’s no big concepts being reached for anyway.
And as far as getting the gigs, I understand they either turn up to premieres or run a services at events? Like the NTA’s as an example, they have people book time slots with them for social media content and there’s essentially enough people that want that, the uptake in influencers being invited to events has essentially given them a job market.
