Propriety release

You're welcome to ask your questions... but I moved this to the right place: Adobe Stock Contributors​, so that the right people can answer.

Not literally but really unrecognizable: No. Exception: Nudes, there you need always a model release and you need to enter proof that the model is 18+. But be careful: people may be recognisable because of tattoos or other marks.

filipap91999922  wrote Second, should I get it propriety release for photographs of logos, for instance, a bottle of an alcoholic beverage like Aperol or Finlandia?

You even do not need to try to submit. Logos are an absolute refusal reason. Also, if the bottle is of a special design (Coca Cola), do not submit as it will be refused. iPhones will be refused on specific design elements like the round knob. Fendt machines will be refused on the green and yellow colour etc. Cars will be refused on specific design elements... All those things would make it impossible to generally use the pictures.

filipap91999922  wrote Third, do you need these kinds of releases for editorial images? Can I submit the photograph solely as an editorial without getting a release? Thank you in advance

No you will not need model or property release for editorial pictures. But there is a different difficulty: Adobe stock does not accept editorial pictures from standard contributors but only from selected press agencies. Other providers allow also for submission of editorial pictures.
