Ssssso... As a fresh possessor of this device who has played a little bit in the last week, I would like to share my thoughts.

Settings that I now use on the camera and explanation for my choices

- Formats: High Efficiency
I compared it with the JPEG (most Compatible) and there is no real gain in terms of details, colour balance, reducing the overprocessing: I indeed prefer my images to take less space, so the HEIC sounds a good compromise for me

- Apple ProRAW: ON (it adds the switcher in the camera app)
ProRaw Resolution: 48 mp
images are unreally good in terms of details, colour, exposure and general quality of the image: the comparison with the 12mp ProRaw is sometimes not even possible. OK, I know that the RAW images are meant to be post-processed, but most of the time I am quite satisfied of the "raw" result without modifying it at all.
The big con is, as many of you already know, the size of the photos. A workaround is using a Shortcuts tool that converts a RAW into a HEIC, and I find it the best way to reduce the over processing of the image: in this case the file will occupy 4mb instead of 1,5 / 2 mb of the "normal, non ProRaw" 12mp shot, but I find it a really good compromise. The resulting image will be categorised as 48mp, will have the quadruple of the resolution for only the double of the space occupied. I REPEAT: RAW photos are technically not meant to be used like that, but I am quite confident on the final result for the use that I have taking amateur street photography that will stay only on my phone and not showed at the next Photo-Gallery in New York.

- Preserve Settings: ON for Macro Control, Exposure adjustment, Portrait Zoom and Live Photo
Macro Control: I want to decide when I need the Ultrawide lens with close objects, as the Main sensor is always qualitative better as the Ultrawide
Exposure adjustment: Sometimes in some light conditions I notice a behaviour of the sensor that tends to overexpose the images. In these cases I set the exposure fixed to -0,3 and I leave it as long as I need it
Portrait Zoom: I find the 2x zoom the most practical so I basically leave it so
Live Photo: Always find it a nice feature but I basically leave it off as it takes more space as the normal nonProRaw 12mp one.

- Use Volume Up for Burst: ON
as I use Quick-Take for short videos instead of Live Photos, I need a quick command to take also burst photos without going always back to settings to change it

- Grid: ON
Always useful to take a straight pic of panoramas and landscapes

- Mirror Front Camera: OFF
I like to preserve the reality as it is, not the mirror of it ahah

- View Outside the Frame: OFF
Cool feature, but often confusing as I not immediately understand what will be in the picture and what not

- Photographic Styles: RICH WARM (Tone -20, Warmth 15)
Austin Mann a famous photographer that has reviewed the cameras of the 13 Pro and now the 14 Pro, said that of course he normally shoots in RAW and post-processes it, but when he needs quickly a final product he uses this photographic Style combination as the most versatile and for true-to-life results in terms of colours. Actually his suggestion is Tone -30, but I sometimes found it a little bit more aggressive with shadows and lights, so I reduced it.

- Prioritise Faster Shooting: OFF
From Articles about previews iPhones, I learnt that when this option is turned ON, sometimes the quality of the images is reduced and the processing is more aggressive in order to compensate shacky hands, blurry parts and so on. But I didn't find yet an accurate article about it. I normally take my time to shoot the image, so for me a faster shooting is not a priority and that's the main reason I left it off.

- Lens Correction: ON
I'm not so much a fan of the fish-eye effect of the Ultrawide, so a Lens-Correction is in my use always welcomed.

SO:
- I normally leave the ProRaw OFF, as for the everyday use the 12mp shoots are more than enough. When I am a tourist or when I need more details, i turn it on simply from the camera app and then I decide if I convert it to HEIC with the tool or I leave it as it is;
- I don't feel this "OVERprocessing" situation that much, with these settings I reached a compromise in terms of image quality, colours and general outcome. Only sometimes in some situations (low-light scenarios or strong light contrasts between the subject and the background) the Auto-Post-processing of the phone struggles giving an artificial effect, but with my last iPhone 8 I remember it was basically similar but worse);
- we were used on the practical point and Shoot of the previous iPhones, that generally gave us good images (for the time) without having to modify every time the settings of the camera. I think that this is the main difference that we are not already used to: computational photography is getting more and more complex (not complicated) and sometimes it does not match our tastes on the final image, but that's where the settings come for helping us: it takes more time as before, I know, but the final result is better as years ago in any case.

I appreciate other suggestions from you! How do you find the overall experience? What are the settings that you use by default?
