A few months ago, I started taking 30-minute walks around my neighbourhood. I always bring my pocket camera. I use the native photo app, Halide by Lux, or Adobe Photoshop Lightroom Mobile app on my iPhone 11 Pro.
Halide is a powerful photography tool for mobile devices with advanced manual controls to fine-tune settings like focus, exposure, and ISO. It has an elegant user interface and high-quality image processing.
I subscribe to the Adobe Creative Cloud Photography suite for $10/month, giving me access to Lightroom, Lightroom Classic, Photoshop on macOS or iPad, and 20GB of cloud storage. I also get the mobile applications Photoshop Express and Lightroom Mobile.

Adobe Photoshop Lightroom Mobile is a pocket-friendly tool that packs powerful editing tools, RAW support, and seamless cloud integration. It allows me to capture, edit, and share stunning photos on the go.

One of the reasons I was excited about my new iPhone 11 Pro is that I would no longer have to carry my ILC1 to bars/taprooms/restaurants to get the “bokeh” shot of the beer glass with my pour of craft ale2. I expected that the iPhone camera app "Portrait Mode" would suffice. “Portrait Mode” uses multiple cameras on the back of iPhones and software algorithms to create an artistic depth effect, whereby the subject is in focus, and the background is blurred. It's an attempt to approximate the “shallow depth of field” photographs one can easily capture with an ILC and wide aperture lens.
The image below was captured with the 6mm (52mm FF equivalent) lens on the iPhone 11 Pro but with all the "portrait mode" software disabled.

The following image was captured in Portrait Mode.

I have experimented with the iPhone 11 Pro and Portrait Mode. The software algorithms need some work. It can’t figure out what to do with the space inside the glass but found the “solid” portion of the water in the glass. I tried shooting some beer in Teku glasses, and the algorithm has the “body” of the beer in focus but blurred the stem badly.
I learned that I need the subject of the photo to be still and 2.5 metres or less from the camera. Good lighting is important. My experience is that the effect struggles in artificial light indoors. This "bug" could be a problem for how I want to use the camera, but this is to be expected for such a tiny sensor. Smartphones take great photos outdoors with good light but are complete shite for indoor images that are no challenge for a modern ILC.
But sometimes, it doesn't matter what you do. Sometimes AI is no substitute. The image below was captured outside in bright light on the iPhone 11 Pro in "portrait mode". There are noticeable artefacts around the outer edges of the can and especially the glassware.

You can see from the details below that the iPhone 11 Pro cameras have a fixed aperture and ISO and shutter speed have a narrow range. Compare to my Fuji X-T2 + Fujinon XF16-55mmF2.8 R LM WR lens. The iPhone 11 Pro cameras have a fixed aperture of ƒ/1.8, ƒ/2.0, ƒ/2.2 and ƒ/2.4. The lenses can not be stopped down. The iPhone 11 Pro always shoots wide open. The iPhone 11 Pro cannot shoot at ISO higher than 3072. The slowest shutter speed is 1s which limits its use for long-exposure photography. Without software trickery, the iPhone 11 Pro is limited in its ability to create long exposure images or aperture priority images or photographs in low light.
