With the iPhone SE, you get an array of attributes given its pricing; however, a strong portrait mode doesn’t come with these features. Similar to the XR variant, you will be stuck clicking portrait pictures of the people with the use of your default camera. This is a major problem when one is supposed to stray away from human contact.
However, you might not have to subside for the plain old shots in case you have plans to get the 3rd party tools. Halide has now updated its chief Camera app along with the long-exposure Spectre application to help enable the portrait mode for all non-living objects, & not simply humans.
If you have been planning bokeh for the pet shots & flower close-ups, this particular combination is all that is needed. The Spectre app and halide camera in total would cost you $9 with $3 and $6 for each, respectively. This is a bargain pricing compared to the extra $300 that you might invest in order to bring home the iPhone 11 packed with scope for native portrait-type shots.
Also, you get access to a series of features and manual controls that you won’t get with any generic iPhone.
