Do you guys think it's feasible to take your own photos with a newer iPhone (like 12 or 13, something with three cameras) and a tripod, nothing else?

I don't really know anyone that I'd want to ask for help, and I don't want to invest in a bunch of lighting or other equipment that I'd have no use for otherwise. I'd feel like a retard paying for a photoshoot, plus I think it's going to make more sense to iterate as I slowly upgrade physique, clothing, grooming.
