We are working on a "remove objects from photos" app, where the users highlight/select a part of an image they want to remove and the app takes care of it.

Precision is sort of important here, on one hand, it's not for Pro users, it's a classic B2C mobile app.
On the other hand, we assume users want to remove specific objects, sometimes very subtle.

Currently, when the users move their finger they'll "paint" the same location on the image, which can create issues as the finger "hides" the content underneath it.
We thought about two mechanisms to improve it:

• Add Offset to the finger location:

• Same location, but you Maganfier to showcase what's below the finger:

Would love to hear you suggestions, thanks!
