A pro photographer is unlikely to care about their phone camera. Or at least those that are also hobby photographers and bring a camera regularly.
For example: https://www.gadgetmatch.com/time-covers-shot-iphones/
- Such an important moment is something you often wanna blow up in a large/hi-res print.
- An ultrawide lens is suboptimal for portraits and usually makes the face look puffy from the perspective.
- Unless you know the exact color & aesthetic for the cover you want to preserve the raw capture for changes in post to match the vibe.
While I can certainly appreciate the casual and intimate vibe she’s going for, as a pro she could have brought any decent camera with a portrait lens and keeping the shoots equally short without compromising quality and adding risk for the poor layout person who has to work with it later.
