i pad pro and portrait pics

Apple iPad doesn’t support the iPhone’s Portrait photo mode. More details here:

Use camera modes on your iPhone, iPad, and iPod touch - Apple Support

The so called Portrait mode emulates/renders a shallow depth of field - to produce a synthetic bokeh effect that you would otherwise only be able to achieve using proper photographic lenses.

There are many Camera Apps in the Apple App Store - as there are professional post-processing Apps (e.g., Affinity Photo and multiple Abobe Apps) - from which to choose - each with their own strengths.

The perceived benefit of the iPhone Portrait mode is the Apple proprietary processing - that produces acceptable results without the need for post-processing. Apple do expose this functionality to post-processing Apps by way of API. However, to my knowledge, the Portrait photo mode found in recent models of iPhone are not available to the iPad Camera hardware.

I hope it was helpful in guiding your search for a suitable solution.
