Gcam portrait mode is a feature built into some Android phones, including Google Pixel devices and some other manufacturers, that allows users to take highly detailed and professional-looking photography by separating the background and the subject of the photo in order to create a beautiful bokeh effect. Generally speaking, this mode has been primarily used to take photos of people and pets, with success.
However, while this mode can work with other – non-human – subjects such as landscapes and flowers, the photographic results may not be as dramatic as when using it with people. Moreover, it largely depends on the camera’s hardware capabilities, so it may not always be possible to replicate the same quality of results with all devices, even with the same model. Furthermore, certain features may not be available in all devices, such as the ‘Auto’ mode, which works best with human subjects.
To sum up, while Gcam portrait mode can work with non-human objects, the results may vary significantly depending on the specific phone model and its hardware capabilities.
